How Do Bed Bugs Travel from Room to Room -Keep Them Out

(Newswire.net — July 17, 2019) — Bed bugs can be a real nuisance when they invade your home. A bedbug infestation often means you’ll struggle to sleep in peace because they like to feed on blood by sucking through your skin when you’re asleep. Have you ever wondered how do bed bugs travel from room to room? They spread fast and also breed at a high rate. Before taking any pest control measures, it’s important to understand how they migrate, so you can have a better idea of how to eliminate them.

How Do Bed Bugs Travel from Room to Room

Just like you want to know the signs of a rat infestation and how to eliminate them, it’s the same when it comes to bed bugs. Bed bugs can spread rather quickly, so it’s important to be prepared so you can eliminate the bed bugs before they spread too much. Below are various ways bed bugs can travel to your home and spread to multiple rooms.

Through Breeding

Bedbugs mature fast and the females can lay eggs at a rate of four to seven eggs daily. The eggs are laid in dark places and will usually stick on any hard surfaces such as wood. This makes them spread fast, especially if the eggs are laid on furniture and you move to a different place. Female bed bugs can lay a total of 200 eggs, especially in dark, isolated spaces. The eggs will usually hatch within a week or two.

Through the Movement of Infested Items

Bed bugs live in furniture, beds, bedding or clothing. If you move any of these infested items, then it can carry the bugs, and they’ll continue breeding in the new room or place where the furniture was moved to if the conditions are favorable.


Bed bugs are very good at crawling. They can crawl very fast when it’s dark. For instance, if you feel some bites while you’re asleep and decide to turn on the lights, the chances are you won’t even find one as they travel fast to their hiding places. If you live in an apartment, bed bugs can spread to every home through cracks. They’re also resilient to many pesticides and should you decide to spray an infested home, they simply move to the next room or home.

Movement of People

Whenever people put on clothes that are infested by bed bugs, they move them to other places where they land. For instance, one can collect bugs from one room to another or from a friend’s house to their home. These pests can also spread through traveling with infested packaging boxes and suitcases when one is moving from one residence to another.

Resilience and Resistance

Bed bugs are extremely adaptive and resilient. They can survive for up to seventy days without feeding and can live for several months if well fed. They’re also very sensitive and search for their prey by sensing heat from the human body and carbon dioxide from the mouth. When feeding, they pierce the human body through the skin and spit some saliva that contains chemicals that make you insensitive until they have finished.

Bottom Line

It goes without saying that bed bugs spread fast and their ability to hide in dark spaces encourages their spread. A single infestation can turn into a full-blown infestation in no time, which is why it’s important to keep them awayfrom your home. Once you have an answer to the question: how do bed bugs travel from room to room, you can take necessary precautions and measures.

Nashville among worst bed bug infested cities in the U.S.

“Goodnight. Sleep tight. Don’t let the bed bugs bite.”

NASHVILLE, Tenn. (WTVF) | Emily Luxen |June 3, 2019 — On a week where thousands of visitors from around the world will come to Nashville for CMA Fest, the city is ranked as one of the worst in the country for bed bugs.

A new survey by pest control company Terminix finds Nashville is the 18 th most bed bug infested city in the country. Music City was ranked 21 st last year.

Philadelphia was ranked number one in the report, followed by New York City. Memphis was ranked 17 th .

Terminix said the rankings were based on the number of services the company has performed in the city in the past year.

“A lot of the problem we have here in Nashville is driven by the fact we are a transient city,” said Chris Bryant, a Service Manager at Terminix. “Summer tourism is starting to peak this time of year.”

To prevent transporting or being bitten by bed bugs, Bryant recommended people check headboards, mattresses, and sheets in hotels or Airbnbs for any signs of bed bugs.

“What you are going to be looking for looks like small black dots, like someone tapped it with a black ball point pen,” said Bryant.

Bed bugs are visible, and when fully grown are about the size of an apple seed.

Bryant also recommended hanging all clothing rather than putting it in drawers, and to keep your luggage away from the bed. When you return home from a trip, wash all your clothes in hot water.

The bugs can bite and leave behind red itchy marks on your skin. Bed bugs do not transport disease.

“Especially if it’s at night and you are in bed and you are being bitten by bed bugs, it will wake you up and cause you to itch,” said Brian Todd with the Metro Health Department.

Todd said any bed bug sighting in a hotel should be reported to management immediately. Problems can also be reported to the Metro Health Department at (615) 340-5630. It is helpful to provide the name of the hotel and the room number. The Department’s Environmental Health Bureau will look into the cases.

Bryant said Terminix hoped the study would increase awareness that bed bug sightings are on the rise, and to educate people on how to prevent transporting them.

“It just takes one to hitch a ride on you, and when you go back home, you’ve taken it with you.”

Bed Bugs Don’t Need Beds, or Humans, to Survive. They Never Did…

The rise of bed bugs preceded modern humans by at least 100 million years. They survived the extinction that killed the dinosaurs. Could they outlive us all?

Don’t be fooled by their charming name: Bed bugs don’t need beds to set up shop. These intrepid insects will colonize pretty much any place where people pile up, including hotels, movie theaters, libraries, even the occasional subway—ready and waiting to ruin a human life with their bloodsucking mouthparts and death-defying durability.

It’s easy to dismiss bed bugs as loathsome pests that exist to make humans miserable. But in reality, bed bugs predate humans by leaps and bounds, making us the unwanted interlopers that first crossed into their turf.

According to a newly mapped bed bug family tree, these puny pests have been guzzling the blood of other animals for more than 100 million years, long before the rise of both modern humans and bats, their most common host. The research, published today in the journal Current Biology, shows that the bed bug timeline stretches further back than even the mass extinction that wiped out 75 percent of Earth’s plant and animal species, including all dinosaurs, 66 million years ago.

The surprising longevity of bed bugs means we’re no longer certain of the identity of these bloodthirsty buggers’ first host. But the study’s findings could still offer clues on how bed bugs once made the jump to humans, and if that transition will have an encore act in the future.

“Bed bugs didn’t evolve on humans,” says study author Michael Siva-Jothy, an entomologist and evolutionary biologist at the University of Sheffield in the United Kingdom. “We just happen to be their current host at the moment—which means they’re very good at what they do.”

Bed bug bites are caused primarily by two species—Cimex lectularius and Cimex hemipterus—which pierce human skin and drink blood with their sucking mouthparts. Luckily, neither is thought to transmit disease. Image Credit: smuay, iStock

The scourge of bed bugs on humankind is believed to stretch back to the very dawn of our species. But only three species—Cimex lectularius, Cimex hemipterus, and, less commonly, Leptocimex boueti—routinely spend their nights supping on human blood. At least 100 other types of bed bugs exist worldwide, feeding mostly on bats and, to a lesser extent, birds, and researchers still don’t have a good understanding of these insects’ origins, and how species have split and diversified over time.

To generate a more complete bed bug catalog, an international team of scientists led by Klaus Reinhardt, a molecular and evolutionary biologist at the Dresden University of Technology in Germany, set out to amass insects from around the world.

A handful of specimens weren’t too hard to come by, arriving via the generosity of natural history museums, or scientific colleagues who had seen the team’s requests for help on Twitter. Collecting the lion’s share of the data, however, required some pretty gnarly field trips that featured amateur cliff scaling, treks through knee-deep guano, and hikes into remote mountaintop caves—all in search of nondescript insects just millimeters long.

In all, sample collection alone took the study’s 15 authors the better part of 15 years. But the result was an unprecedented collection of pristine bed bug DNA, representing 34 species hailing from 62 localities around the globe.

“It’s really difficult to collect these specimens,” says Christiane Weirauch, a systematic entomologist at the University of California, Riverside who was not involved in the study. “It’s just so cool that this team has pulled this together.”

By comparing DNA sequences across species, Reinhardt, Siva-Jothy, and their colleagues were able to trace the evolutionary relationships between the bed bugs they’d collected. The researchers then combined their data with evidence from known insect fossils to pinpoint when bed bug lineages had split in the past. And when the bed bug family tree was finally mapped, the team was met with a set of findings that flew in the face of almost everything they’d expected.

Because bats remain the most common host of bed bugs (technically, bat bugs) today, Siva-Jothy says, most researchers have assumed that the first bed bugs to scuttle the Earth also gorged on the blood of these winged mammals. Cozied up to cave-dwelling bats, bed bugs would’ve then had an easy time making the hop to our human ancestors seeking shelter some 2 million years ago, and evolved alongside the genus Homo ever since.

Neither of these theories panned out.

The researchers’ analysis now places the origin of bedbugs around 115 million years ago, during the Cretaceous—a whopping 30 to 50 million years before bats are believed to have come onto the scene. It’s not yet clear what species first drew the bed bug straw, but a good candidate might be a small, social, cave-dwelling mammal, Reinhardt says.

Others, however, aren’t ready to completely rule out bats, or at least an early bat-like ancestor. “The fossil records for [both bed bugs and mammals] are patchy…that makes it hard to make definitive statements,” says Jessica Ware, an entomologist and evolutionary biologist at Rutgers University who was not involved in the study. “It’s possible bats are older, and we’ve just underestimated.”

Some 70 more bed bug species have yet to be analyzed in this way, and the family tree could still change with the addition of new data, Ware says. “That being said, this is the first and maybe most comprehensive analysis people have done for [this group of insects].”

Regardless of where, and on whom, bed bugs got their start, it appears these insects were hardy enough to weather a mass extinction—and have remained alarmingly adaptable ever since. The researchers’ findings suggest that, throughout their evolutionary history, several bed bug species went from bothering bats to terrorizing birds and vice versa. Along the way, at least three species dipped their spindly legs into human stock. Surprisingly, all three species appear to have evolved independently, with each making a separate jump to human hosts.

In other words, we humans didn’t actually do much to shape the evolution of one of our most iconic pests, who were perfectly content binging on the blood of bats and birds. It just so happened that, when an unlucky member of the genus Homo stumbled onto their path, certain bed bugs were flexible enough to expand their palates.

Bats were once thought to be the first host of bed bugs. But a newly mapped family tree shows that bed bugs predate bats by 30 to 50 million years. Image Credit: Mark Chappell, University of California, Riverside

There’s even a chance another bed bug species might one day develop a taste for human blood, Reinhardt says (in fact, it might already be happening). Based on the historical data, these transitions happen roughly every half a million years.

But the more pressing concern might be the enemies we already know, Siva-Jothy says. “With human populations expanding, and our reliance on animals, and the way cities grow and communicate…there will be more opportunities for the species we’ve already got to become more widespread.”

Given the stubbornness of bed bug infestations, that’s not great news. It’s enough to make us wonder if bed bugs have the apocalyptic armor to outlive us all.

We might not have made our bed bugs. But we still have to lie with them.

Here’s how California could be missing pesticides’ cancer risk – #sayNOtoPESTICIDES!

February 17, 2016 | by Andrew Donohue | Reveal

The local community is concerned about high levels of pesticides used near Rio Mesa High School in Oxnard, Calif., which is surrounded by strawberry fields on all four sides.

California’s pesticide police could be missing a serious health concern for residents and farmworkers by failing to monitor what happens when pesticides get mixed together.

As a new report from UCLA highlighted today, California studies only how each individual pesticide affects human health. Often, however, workers and residents are exposed to a number of pesticides at the same time.

That can happen when pesticides get mixed together before they’re applied to fields or when different pesticides are used in the same field on the same day. A growing body of science is showing that the chemical cocktails could create greater health risks than each pesticide does on its own.

In particular, the report shows how three fumigants – a type of gaseous pesticide central to the strawberry industry and used near schools and homes – might combine to increase the risk of cancer for bystanders. Essentially, once in the human body together, the chemicals can team up to attack and mutate DNA in a way they wouldn’t on their own.

“The regulatory system that is supposed to protect people from harmful levels of pesticide exposure has been slow to deal with interactive effects when setting exposure limits for pesticides,” the report says.

The California Department of Pesticide Regulation’s mission is to protect humans and the environment from the dangers of pesticides. The report’s authors, who come from UCLA’s law and public health schools, said the department must begin studying the combined effects. And they point out that low-income and minority residents are at the greatest risk.

“DPR is required to assess this risk and protect public health, but isn’t doing so,” the authors wrote.

The department already is under fire for how it has managed fumigants, which can spread easily through the air. A Reveal investigation found that department leaders allowed growers and Dow AgroSciences to use heavy amounts of one fumigant despite strenuous objections of scientists because of its potential to cause cancer.

When Ventura County residents subsequently raised concern about the pesticide’s use in strawberry fields near Rio Mesa High School, department Director Brian Leahy responded with a series of exaggerations and contradictions.

The department has curtailed the pesticide’s use and begun drafting rules that would limit pesticide use around schools and require residents to be notified of fumigant use near their homes. However, the state continues to keep open the loophole it created at Dow’s request.

Last week, the department’s second-in-charge, Chris Reardon, left without explanation after nearly 13 years with the agency. An appointee of the governor, Reardon maintained close ties with the agricultural industry, copies of his calendars show.

The UCLA report focused on the fields around Rio Mesa High School to make its case. The school is boxed in on all four sides by conventional strawberry fields. Although pesticides aren’t applied during school hours, the gases can linger in the air for weeks after they’re applied without teachers or students knowing.

Combined, the health risk could be much greater than those of the individual pesticides.

“In fact, modeling shows that over the course of about one week people who live and work in the area around Rio Mesa High School in Ventura County were exposed to large doses of multiple fumigants,” the report says. “This level of exposure raises concerns about possible interactive effects.”

The report points out that 35 percent of all fumigants were applied on the same field on the same day as another fumigant, and 26 percent were applied as part of a pesticide mix.

The authors recommend the following changes in California’s pesticide regulation:

  • Pesticides sold as part of a mixture should be tested before being approved for use.
  • When pesticides are mixed at the field or applied near each other, regulators should require testing or create strict restrictions if there’s a reasonable chance of human harm.
  • The combined effects of the pesticides should be considered in the initial health research done by the Department of Pesticide Regulation and the rules it creates around the pesticides’ use.


Misled About BedBugs? Ask Real Estate

Michael Kolomatsky/The New York Times

The New York Times | by Ronda Kaysen | November 21, 2014

Q. My wife and I recently signed a one-year lease for an apartment. It included a rider stating that all apartments in our building had been bedbug-free for at least one year before our move-in date. After we moved in, we learned from the superintendent that an apartment in our building had been infested by bedbugs and treated a few weeks before our move-in date. Needless to say, we were disturbed by this news — and want to know our rights. As we understand it, the landlord is responsible for the costs of fumigating. Who is responsible for other expenses, like replacing mattresses and furniture? Since we were misled (and have the signed rider as proof), can we demand remuneration for any repairs or replacement costs we might be forced to incur?

A. There are two plausible explanations for what happened here, neither of them good. Either your landlord was woefully ill-informed about the state of the building or he lied. In either case, I would be concerned about how effectively the infested apartment was treated for bedbugs, which are notoriously hardy creatures.

“If this is a landlord who is willing to lie on a disclosure form,” said David Hershey-Webb, a lawyer who represents tenants, “then the tenants may not have a lot of faith in the landlord to adequately address the bedbug problem.”

The New York City administrative code requires landlords to disclose whether or not an apartment has been treated for bedbugs in the last year. The measure does not include any penalties for violating the law. However, if you do get bedbugs and incur damage to your personal property, you could take the landlord to small claims court and use that erroneous disclosure form as evidence of negligence. Under normal circumstances, a landlord is required to treat the infestation and a tenant is responsible for cleaning personal belongings, Mr. Hershey-Webb said.

But before we wander too far down the road of future infestations, determine your risk. If the affected apartment is adjacent to yours or in the same line, you have good reason for concern. But if several floors and walls separate you from that apartment, your risk is considerably lower.

“If it’s an immediately adjacent unit or if it’s in that line, it could have an effect,” said Gil Bloom, the president of Standard Pest Management and an entomologist. “Outside of that, it normally does not make a difference.”

Once you have assessed your risk, decide whether you want to stay in the apartment. Ultimately, you might want to consider packing up your belongings and moving out before the bugs move in. You “have the option to try to rescind the lease on the basis of fraud,” Mr. Hershey-Webb said. Consult with a lawyer to see if you can get out of the lease. Otherwise, you may find yourself battling a bedbug infestation with a dishonest landlord.

BedBugs reported in some of NYC’s swankiest hotels. They were always there; and it’s getting worse. More important to follow as BedBugs transmit deadly Chagas disease.


Baby Roaches (Pictures): 12 Simple Ways to Get Rid of It for Good

Most babies in the animal kingdom are adorable, but baby cockroaches? Far from it. It’s not necessarily their appearance that’s alarming – although they can be creepy, too. What’s most concerning is the fact that baby roaches usually mean you have a nest somewhere in the house.

You’re not dealing with an isolated visit from Bob and Nancy Roach. No, the entire family has taken up shop in your home – somewhere you can’t see.

If you’ve never dealt with a cockroach invasion before, you may be wondering what a baby, or nymph, roach looks like and how to get rid of them for good.

Table of Contents

What Do Baby Roaches Look Like?

Like other animals, baby cockroaches are just miniature versions of adult cockroaches. The primary difference between the two (aside from size) is that babies lack the wings their adult counterparts have.

Babies may also be lighter in color than adults. The baby German cockroach, however, is usually darker than adults.

Baby Roach Pictures

These photos will give you a better idea of what baby roaches look like:

Baby Roaches Multiply Fast

You see insects all over the place and you don’t need to have a meltdown as such, so why is the presence of a baby roach in the kitchen something to fear? We mentioned that seeing one baby roach means there are bound to be more – a baby roach doesn’t suddenly break free from the nest, travel miles and then decide to dwell in a house, they always come in multiple numbers, sometimes highly multiple. Of course, there is the chance that the rogue roach was transported into your home by accident, e.g. in a box, but that is quite an unlikely scenario in the real world.

Cockroaches are fast reproducers. Think about rabbits and put it on high speed and you’re somewhere close! A female cockroach’s egg pouch holds 16 eggs in total, and they produce two of these pouches a week. Can you see how fast that number multiplies? The multiplication goes on, and with half of these babies maturing fast and having their own babies; the risk of a severe infestation is quite high. In addition, if you have German cockroaches, you should worry further, because a female of this type can hatch around 300,000 babies every single year. So, you can imagine the sight of just one baby should have you trying to figure out the best cockroach traps around.

The bottom line here isn’t that a cockroach should have you worried in terms of harm, because they aren’t going to hurt you, other than give you a mild heart attack when you see it scuttling across the floor. The problem is more about the sheer number of them, and how difficult it can be to rid you home of them once the infestation takes hold, which it can do quite rapidly if action isn’t taken.

What Does a Baby Cockroach Look Like?

An adult cockroach has an oval-shaped, flat body that’s oily to the touch. These critters have small heads and are covered by a pronotum. Their mouths are backwards and directed down.

Roaches have six legs that are long and spiny, so they can quickly skitter across surfaces. They also have special little pads at their tarsi that let them walk across ceilings and up walls.

Some roach species have wings that lay flat against their backs, but not all of them use their wings for flight.

Female roaches are usually bigger than males. In some species, the females don’t have wings, but the males do.

To help you get a better idea of what adult roaches look like, here are a few descriptions of the most common species:

  • Baby American cockroaches: Reddish-brown in color and around 40mm in length on average.
  • Baby German cockroaches: Dark brown in color and 13-16mm in length on average.
  • Baby Oriental cockroaches: Black in color and larger than German cockroaches.
  • Baby Pennsylvania wood roaches: Tan in color and about 20mm in length on average.

Identifying (Baby) Cockroach Eggs

If you’re seeing tiny roaches in your home, there’s a good chance there’s a nest in the walls or near your home. Knowing what cockroach eggs look like can help you identify a nest if you’re trying to tackle the problem at its root.

A female cockroach produces an egg case known as an oothecae. A single oothecae can have a large number of eggs, and each is enveloped in a protein substance. That substance eventually hardens to create a protective casing. Some females will drop the egg case, while others will carry it with them until the eggs are just about ready to hatch.

American Cockroach Eggs

Female American roaches will leave dark brown oothecae that are about 8mm long. A single female can make between six and 90 of these cases in her lifetime, and they carry the case with them for anywhere between a few hours and a few days. When she’s ready, the case will be deposited in a hidden location.

Each oothecae contains about 15 embryos. Babies will emerge from the oothecae in 24-38 days.

Oriental Roach Eggs

The oriental cockroach produces a dark reddish-brown egg case that measures 8-10mm in length. These oothecae have a slightly swollen appearance and contain about 16 eggs.

Females will produce anywhere between one and 18 oothecae in their lifetimes.

Oriental roach nymphs take about 600 days to reach full maturity, but the length of their development is largely dependent on their environment.

Brown-Banded Roach Eggs

The brown-banded roach species creates a light reddish-brown egg case that’s about 5mm long. Females can make up to 20 oothecae in their lifetimes, and each one contains between 10 and 18 embryos.

Nymphs are easily identifiable because they have a signature yellow band across their upper abdomen.

It takes three to six months for brown-banded nymphs to grow into full adults.

German Cockroach Eggs

Female German roaches produces an oothecae that’s brown in color and between 6 and 9 mm long. These females will actually carry the eggs inside until they’re ready to hatch.

Each oothecae can contain up to 50 eggs. It takes about 103 days for a German roach to go from egg to adulthood.

With so many eggs in one oothecae, German roach populations can grow very quickly. Because these are the most common species to invade homes, it’s important to tackle the problem early on before the infestation becomes a serious one.

How Long Do Baby Roaches Stay Babies?

Roaches are just like other insects in that they reach adulthood by going through several molting processes at different stages in their lives. Nymphs hatch from their eggs after 20-60 days.

Eventually, babies will develop wings and complete a series of molts to grow into adults. There’s a transitional phase in between each molt known as an instar. Usually, a baby will go through six to seven instars before becoming a full-grown adult. This process takes between 40 and 160 days, depending on the species of the roach and the temperature of the environment.

The Risks of Having Baby Roaches in the House

No one likes having roaches in their home, but can they be a risk to your health? What about baby roaches? Can they cause damage, too?

Yes, yes and yes.

Baby and adult roaches can both carry disease, which can spread quickly throughout your home if you don’t act swiftly.

Roaches feed on garbage and they breed in sewage. Babies can just as easily carry viruses and bacteria on their bodies, and spread these germs around your home. They can contaminate food and food surfaces in the blink of an eye.

And in case you didn’t know: roaches can carry up to 30 different species of bacteria that can cause: plague, diarrhea, viral diseases, cholera, dysentery, leprosy, typhoid fever and other diseases.

The last thing you want is to have your family get sick because some roaches decided to invade your home. Tackling the problem early on (and keeping your home clean) can help prevent this from happening.

Along with disease, baby roaches can also affect people who suffer from respiratory conditions, like allergies and asthma. You may notice that you’re coughing and sneezing more than usual because of the roaches in your home. Roaches produce a type of protein that can trigger an allergic reaction in humans.

Baby and adult roaches can cause these symptoms because of their molted shells. Baby roaches leave these shells in large numbers as they go through each stage of molting. They can be left all over the house, which can trigger symptoms at any time and virtually anywhere in your home.

Roach saliva, waste and even dead bodies can all trigger allergic reactions or asthma attacks in certain people.

And if you fail to take care of your baby roach problem, you’re going to wind up with a serious infestation in the very near future. If you’re seeing small cockroaches, it means the adults are reproducing and there’s a nest nearby. They certainly won’t stop reproducing because you ask them to. You’ll need to take care of the problem – sooner rather than later.

You know that German roaches can lay up to 50 eggs at a time. Imagine having 50 new baby roaches suddenly emerge in your home – not a pretty picture. And females will produce several egg cases throughout her lifetime.

Baby roaches are a sure sign that you have an infestation somewhere in your home or building. The roaches are obviously reproducing, and the babies are hatching. It’s only a matter of time before you have a serious infestation and potential health hazard on your hands.

Every baby roach that’s in your home has the potential to produce hundreds of more roaches. Populations can easily get out of hand – and quickly – if you don’t take steps to remedy the problem now .

The bottom line? Don’t wait around to see if these risks emerge. Get rid of the roaches as soon as you see them to prevent a serious infestation.

Understanding Baby Roach Behavior

Now that you understand the risks of letting roaches hang around, it’s time to start taking steps to get rid of them. Having a good understanding of how roaches behave and operate will help you find the best strategy to chase them out of your home for good.

Roaches Live in Groups, but Aren’t Social

Cockroaches aren’t particularly social creatures, but they do prefer to live in groups. Interestingly, roaches make the decision of where to live as a group. In one study from Free University of Brussels, researchers found that when a space was large enough, the entire group stayed there. When a space was not large enough, the larger group split up into two smaller groups to fit into the enclosures comfortably.

Roaches May Have Collective Intelligence

Other studies suggest that roaches may actually have collective intelligence that’s based on the decisions of individual roaches.

A group of researchers in Europe created a roach robot that mimicked their behavior. Pheromones were applied to the robot, so the other roaches would accept it as one of their own.

The researchers found that that act of the robot roach influenced the behavior of the group overall. For instance, the robot roach convinced the group to move from darker areas to lighter areas.

Researchers say they may be able to use this to their advantage to control roach populations.

How to Get Rid of Baby Cockcoaches for Good

Want to learn how to get rid of roaches in the house? The process is no different than what you’d do for adult roaches, and every method will work just as well no matter whether the roaches are in the kitchen, bathroom or bedroom.

Use the methods below to effectively kill and get rid of the roaches in your home.

1. Seal Up Holes and Cracks

Caulk and foam will keep new roaches from getting into your home. And if they haven’t set up a nest inside your home yet, caulking may be the only thing you need to do to get rid of them.

See also:  Ant Emoji

The first thing you need to do is locate any potential entry points for the roaches. These are areas that may have cracks or gaps that these critters can crawl through, including:

  • Baseboards and molding
  • Interior pipes
  • Walls and floors
  • Decks, porches and steps
  • The roof
  • Doors
  • Windows
  • Exterior pipes
  • The home’s foundation

Go through each of these areas with a fine tooth comb to look for cracks or holes, and mark off which areas need to be treated.

The next step is to fill in the gap with either caulk or foam. Which one should you choose?

  • Use caulk for gaps that are smaller than 1/2”, areas that require a flexible seal (such as joints), areas that are easily visible and require detailed work.
  • Use foam for larger gaps that are bigger than 1/2”, cavities that are hard to reach, dry areas with little-to-no moisture, or instances where insulation is needed.

How to Use Caulk to Seal Cracks and Gaps

  1. Clean the surface area. Remove any old caulk from the area and clean off dirt or loose debris with a caulk-removing tool or cloth.
  2. Apply masking tape on each side of the crack to create a straight edge.
  3. Prepare the caulk tube. Start by cutting the nozzle to the appropriate length and piercing the inner seal with a knife or stiff object. Place the tube in the caulking gun.
  4. Squeeze the gun with consistent pressure for even application of the caulk.
  5. Use your finger or a smoothing tool to smooth out the caulk.
  6. Remove the masking tape.

How to Use Foam to Seal Cracks and Gaps

  1. Put on the appropriate safety gear, including gloves, goggles, protective clothing and respiratory protection.
  2. Shake the foam can vigorously for about a minute.
  3. Screw the dispenser onto the can valve, taking care not to activate the valve.
  4. Invert the can and depress the trigger to apply the foam to openings.
  5. Release the trigger about five seconds before you reach the end point, making sure you keep the straw moving all the way to the end.
  6. If the crack or gap is deep, allow the foam to cure completely before applying a new layer. Leave uncured foam untouched.
  7. Trim excess cured foam as needed.
  8. If the foam is exposed to sunlight, it must be stained or painted.

2. Clean Your Home

Once you’ve sealed up all the cracks and gaps in your home, it’s time to tidy up the place. Keeping your home clean is the first (technically, second) step to getting rid of cockroaches.

Roaches are only in your home for three reasons: food, water and shelter. You have plenty of each. If you eliminate food, they have little reason to stick around. And if you can also keep them from getting to any water sources, they’ll be out even quicker (or they’ll be dead).

  • Don’t leave food out in the open – ever. Keep all opened bags or boxes of food in sealed, airtight containers or Ziploc bags.
  • Wash dirty dishes immediately. Do not leave any leftover food on your plate – scrape your plates into the garbage.
  • Take out the trash regularly. Garbage will keep the roaches around, so make sure you take out the trash on a regular basis.
  • Clean thoroughly underneath and behind appliances, like the oven and refrigerator. Food crumbs have a way of sneaking into these areas, and roaches love to frequent these spots because they’re so dark.
  • Wipe down your counters at least once a day, but particularly after eating or preparing food.
  • Sweep and clean the floor after cooking to remove any leftover food particles.

3. Use Roach Traps

Experts suggest using traps before you run around spraying roaches with bug spray or laying down powders. Why?

Traps will let you see if you’ve caught any roaches, and how many you may be dealing with. If you haven’t caught any of these critters, you can move the trap to a new location to find out where they’re coming from.

Once you’ve figured out where the cockroaches are coming from, you can use powders or sprays if you like.

4. Use a Natural Roach Repellent

If you’re not keen on the idea of spraying poison or laying down powder throughout your home, there are natural roach repellents you can use. Research has shown that the following repellents are actually effective:

  • Eucalyptol, or ceneole, which is found in bay leaves. Leave dried bay leaves in areas where the roaches are frequenting to keep them away.
  • Nepetalactone, which is found in catnip. Leave catnip where the roaches are hanging around, or place it inside cracks or gaps to keep them out of the home.
  • Osage orange oil. Scientists still aren’t sure which active ingredient in this oil repels roaches, but they do know that it works very well for this purpose.

Natural repellents are great for keeping roaches out of your home, but do be advised that this is not the best route to take if you’re dealing with an infestation.

5. Borax

Borax is another simple solution that can get rid of roaches relatively quickly. This simple powder, which is typically used as a household cleaner and laundry booster, dries out the roach’s exoskeleton, so they dehydrate and die.

Borax isn’t an instant killer, but they will drag the powder back to their nest where they may infect other roaches.

Sprinkle borax where roaches tend to frequent – behind or underneath appliances, kitchen counters, etc.

While borax is mostly non-toxic, you should not leave it out where kids and pets can reach it.

6. Soap and Water

If you’re dealing with just a few roaches, you can use a simple soap and water spray to kill them. Yes, roaches can survive in water, but it’s not the water that’s supposed to kill them.

The soap clogs their pores, which causes them to suffocate and die.

7. Boric Acid and Sugar

Boric acid is another excellent roach killer, and it works in a similar way that borax works. But boric acid is more toxic than borax, so keep that in mind and do remember to keep it out of reach of kids and pets.

The boric acid will kill the roach, but the sugar is what will attract him to the area.

Once the acid comes in contact with the roach, it will dry out its exoskeleton, causing it to dehydrate and die.

The only downside to using this method is that you’ll have to clean up a lot of dead roaches in the morning.

Tip: Please do take the time to clean up the dead bodies. Other living roaches have no problem eating their dead, so you’re leaving behind a food source for nest mates to come feast on. Also, dead roaches can produce a stench that no one wants to deal with.

8. Get Rid of All Standing Water

If the roaches aren’t after food, they’re definitely after water. If you have standing water anywhere in your home, you’re basically inviting roaches to come inside and stay awhile.

Something as simple as soaking water in the sink or forgetting to let the water out of the bathtub can attract roaches. And if you have leaky pipes, you’re just asking for an invasion.

Fix any leaks and stop leaving standing water in your home to deny roaches the water they desperately need to live.

You can also go the extra mile by using a dehumidifier in your home to get rid of any moisture in the air that may be attracting these pests.

9. Hire an Exterminator

Sometimes, the DIY approach does not get rid of the problem – especially if you have a serious infestation. In this case, you’ll need to hire a professional exterminator to get rid of your roach problem once and for all.

And if you live in an apartment building, an exterminator may be your only real option.

A professional will have the tools, skill and knowledge to know where to find the nest and the best possible strategy to eliminate roaches from your home.

Please note that exterminators will use chemical sprays, or poison, to get rid of the roaches. Let them know if you have pets or children, so you know how to proceed without putting anyone at risk.

Some exterminators may offer alternative solutions, but most will go with the tried-and-true chemical spray to get rid of the roaches.

10. Use Cockroach Sprays

These sprays are designed to work on small nests and infestations, so that means you need to know where the roaches are coming from in the first place. If you have figured it out, a killer spray could be a good option, and one which is very readily available and quite lost cost. You should certainly target the popular areas for roaches to hand out too, such cracks, doors, windows, and crevices. If you see a roach running free, spray it too – bear in mind they are very fast, despite their size

11. Buy a Cockroach Bait (Read Review Here)

The word ‘bait’ gives it away. You’re basically luring them out so you can kill them from the source. This method is also much cheaper than hiring an exterminator to come into your home, so this is a good first option before you realize you need to up your game even further. Cockroaches aren’t the easiest things to kill, so it could very well be that you need to enlist the help of the professionals in the end, if your efforts haven’t worked, and if the infestation is growing.

Cockroach bait works on the idea that when baby roaches come out of their nests looking for something to eat, they will take the bait and go back to their nest with it. Not only will this be poisonous to that particular baby roach, therefore killing it, but it will also go back to the nest with them, and kill even more, therefore targeting the source. We should also mention that it is not unusual for adult roaches to kill their own offspring if they are hungry enough, so if a roach has gone back to the nest and died, eating that dead roach will mean that particular roach also dies, by proxy.

Of course, you will need to set the bait around your kitchen, or wherever they are, and you will need to be careful that small hands, e.g. children, or pets don’t come into contact with the bait accidentally. Gel baits are very popular and they are quite low cost too, so this is something you could think about, provided you’re careful with the aforementioned pets and children around your home, of course.

12. Use Insect Growth Regulators (IGRs)

An IGR won’t kill the roaches outright, but it will prevent them from reaching maturity and reproducing. IGRs play such an important role in extermination because they keep the problem from getting worse.

Let’s say that you use a roach fogger in your home, but there are a few stragglers left behind. Those few roaches can easily repopulate the dead roaches, compounding your problem and forcing you start back at square one.

But if you use an IGR, those straggler roaches won’t be able to reproduce. Once they’re dead, your roach problem is dead.

IGRs work by providing roaches with juvenile hormones, which prevent babies from molting and turning into adults.
