At what temperature do the pinworms die and their eggs die?

There are a lot of parasites in our world, but the most popular are pinworms. This is due to the fact that during his life each person has had an enterobiasis at least once.

Many tools and preventive measures have been invented to fight worms. Another not unimportant factor that makes it possible to eliminate the eggs of pinworms is the temperature.

Favorable for the development of pinworms is a temperature of 35-40 degrees. At the same humidity should be at least 70%.When the level of humidity decreases, egg development stops.

When performing preventive measures, it is necessary to know that pinworms die at the following temperature:

  • If you wash things at 70 degrees, the parasite and its eggs are destroyed after 5-10 seconds;
  • At 60 degrees the worm can live no more than 5 minutes;
  • At 50 degrees the life of the worm stops after 10 minutes.

Knowing at what temperature pinworms die, you can safely take up their elimination. With helminths and their eggs you can fight and at low temperatures, especially this is good to do in the winter period:

  • At -15 degrees, pinworm eggs die after 60 minutes;
  • At -25 degrees — after 30 minutes;
  • At -35 degrees — after 3-5 minutes.

From this it follows that for efficiency, washed laundry can be carried to the frost. If some pinworms do not die at high temperatures, they will surely be destroyed in the cold. Fruits and vegetables are also recommended to be stored in the refrigerator, so that eggs on their surfaces lose invasive properties.

In the event that there is a sick child in the house, it is necessary to process underwear and other things 2 times a day. Knowing, under what conditions, pinworms die, you can easily process and wash things.

Do not forget about toys. Parasites during games can get on both soft and other toys. To kill the eggs of pinworms, you should carefully treat everything with hot soapy water.

If you do not want to wait for helminths to die under the influence of temperature, you can contact specialists. Doctors will advise which medication to cope with a parasite that has settled in the human body. Also, do not forget about disinfection by special means that eliminate the helminth and its eggs, even under normal temperature conditions. Helminthes can not develop in a clean apartment.

What Temperature Kills Bed Bugs?

Just how hot or cold does it need to be in order to kill bed bugs?

Nearly every insect (and animal for that matter) has a maximum and minimum temperature that they can survive. So what temperatures can bed bugs survive?

What Temperatures Will Kill Bed Bugs

100% Death Rate
115 °F or hotter — All bed bugs (and eggs) will die within 7 minutes of exposure.

Most will Die
113 °F to 115 °F — Bed bugs will begin to die out, but a few may survive.

No Effect
61 °F to 112 °F — Bed bugs will be able to survive and flourish.

Enter Hibernation Stage
14 °F to 60 °F — Bed bugs will enter a hibernation cycle which will help the to survive the cold.

Most will Die
-25 °F to 14 °F — Bed bugs will not be able to survive the cold for more than 5 days.

100% Death Rate
-26 °F or colder — Bed bugs will die within 15 minutes.

At what temperature do bugs die and their eggs die?

The last couple of weeks of cold weather that followed unseasonable mild weather brings up some questions as to how insect pests will react to this situation. Spring-occurring insects have adapted to the various situations that can occur with early, late, wet, and dry springs.

Insects are cold-blooded animals, meaning that their body temperature is similar to that of their surroundings. They do not maintain a body temperature as do mammals and birds. Most insects do not develop or function well at temperatures below 50?F. This base temperature varies a few degrees up or down, depending on the insect species, but is near 50? for most insects. When the temperature hangs between freezing (32? F) and 50?F, insects typically go into a dormant state in which body functions are greatly slowed down.

An interesting feature is that plants appear to develop at temperatures somewhere in the 30s and above. When temperatures hang in the 40s for an extended period in the spring, plants continue to expand leaves and grow stems, and they can get ahead of their insect pests that are present but not developing. As a result, insect pest populations may be typical, but plant damage caused by those pests may be much less than normal.

At temperatures below freezing, many insects that are present during the summer die. However, many spring occurring insects survive temperatures in the 20s, becoming active again once temperatures rise above 50?F. Fewer species survive temperatures that drop into the teens. With the temperatures that we have experienced over the past few weeks, many of the insect pests and their natural enemies that are insects will have died. However, many of them will have survived.

Insect populations typically do not emerge at once. Some hatch from overwintering eggs or emerge from overwintering pupae early, and some of the same species emerge later. This is obvious each spring with the different sizes of eastern tent caterpillar tents and corresponding different-sized caterpillars within them. The smaller tents and caterpillars represent egg masses that hatched later than others. A similar feature can be easily seen in the summer with fall webworm.

Thus, when the cold weather occurred, not all spring- occurring insect pests and natural enemies had hatched or emerged from overwintering stages. Even if the early-hatching and -emerging insects were killed by the cold weather, some will hatch or emerge after the cold temperatures. This may result in less damage to plants due to the loss of the early insects, reducing the overall number of insects attacking the plants. This year, much of the plants� foliage was killed by the cold weather, and the later-hatching and -emerging insects will be present to feed on the replacement foliage as it emerges.

In summary, the insect pests will survive but will probably be less numerous. They will be present to feed on the replacement leaves, so that insect damage will be found. However, the damage due to spring-occurring insects will probably be less than normal. This weather will have little, if any, effect on insects that typically emerge later in the growing season.

Does Cold or Heat Kill Bed Bugs?

—> Bed bugs are sensitive insects when it comes to temperature. A fact is that there have been many myths about what temperature to use to kill bed bugs and about various DIY heat treatments.

Furthermore, you cannot eliminate the pest by turning the heater up or down during winter. On the other hand, leaving your items infested with the bug is not a big help. —> —>

Alternatively, you cannot leave the items outdoors on sunny days. So what is there to do? Please read the full article here to find out what temperature you need to achieve to get rid of them. —>

Does Cold Kill Bed Bugs?

Have you tried DIY methods to save costs on expensive treatments get rid of bed bugs and their eggs?

Well, then you know how difficult it is to get rid of them. A fact is that only extreme cold temperatures can kill the eggs and bug with a reasonable success rate. —>

The truth is that the pestilence, according to studies can die at freezing temperatures lower than 3° F. According to these studies, the insect can die within an hour while other researchers suggest sometimes it can take up to a week.

Either way, it is possible to leave infected items outside to freeze them but not foolproof and it is know that in certain conditions bug survived extreme cold. On the other hand, the small blood sucker does not like it when it gets too hot or cold.

—> Here you can view a study by author Joelle F. Olson in the Journal of Economic Entomology. In the study, he looked at different stages of their lives to find out how quick they die when frozen. —>

Joelle found that bed bugs are tolerant to cold to an extent. However, compared to other insects, the bed bug is not good at supercooling to keep the chemical and physical tactics unfrozen.

Therefore, the insect is vulnerable to cold.

So what temperature will kill bed bugs?

In most cases, the pest can die at temperatures that are lower than 3°. Unfortunately, it does take up to 80-hour to kill off the bug.

With temperatures lower than 4° F it can take up to two days while other studies such as the Medical & Veterinary Entomology suggests differently.

—> According to the research, the bug dies within an hour at 4°.

So can bed bugs survive cold rooms?

Yes, they can unless it gets cold enough in the home to kill the bug. The only thing you can do is to lower the temperature that is cold enough to prevent them from biting often. —>

So why does this happen? Here is why it takes the bed bug longer to digest the food and feed less. At the same time, the insect grows slower and lays fewer eggs.

Just the difference in the degrees helps lessen the infestation. However, this is not the solution as you want to rid your entire home of the problem.

The only time they become inactive at 50° Fahrenheit and stop feeding, mating, and laying eggs. Another problem you face is to get all the bed bugs into bags or leaving your furniture outdoors in the cold is not the best solution.

So what is there to do as the bed bug can survive outside in winter and can survive if frozen to death in freezing temperatures at a certain degree.

Can You Freeze Bed Bugs with CO²?

Yes, you can as use this old method but not as widespread as using heat treatment or pesticides. —>

There are kits you can buy online, but it is expensive and not used for this reason. The Cryonite kit comes with a tank placed on wheels with an applicator and trigger.

Using CO² does have it upside as it is environmentally friendly since the carbon dioxides recycled. What you do is to starve the bed bug from oxygen.

However, it does come with some drawbacks as well:

  • It would help if you gauged the carbon dioxide levels and require special equipment to achieve this.
  • You cannot kill bed bug eggs with CO² unless you have a 100% application.

Does Heat Kill Bed Bugs?

One of the most effective pest control methods is to eliminate beg bugs with heat. The reason is that the insect cannot survive temperature above 140° F.

—> With this type of heat, it spreads throughout the home to each room making it hotter as everything heats up killing them.

Therefore, you do not need to hunt them down as the high temperatures do it for you.

So can you use your hairdryer to kill bed bugs with heat?

You may think using your hairdryer is the best way to get rid of bed bugs, but you will need to maintain the heat over them.

In most cases the hairdryer reaches a max temperature of 150° but maintaining the heat is a different story.

Therefore, you need the right tools for bed bug heat treatment, such as a high-pressure steamer. A steam cleaner reaches past 200° and penetrates deep into mattress and box springs, fabric, gaps, and furniture.

Other alternatives are using a portable bed bug heater like the ThermalStrike Ranger or ZappBug Oven to treat household items. —>

So what can you do if you have the bug in your vehicle and will bed bugs die in a hot car?

If you are one of the unfortunate people to have this problem, you can expose them to heat up to 120°. Furthermore, it depends if you live in an area with extreme heat.

You can spread out the seat covers and mat in direct sunlight, or you can use a high-pressure steamer to achieve the best results.

You might want to check out my other post – What do bed bugs eggs actually look like?

Summing It Up

Taking all the information into consideration the lethal method is using heat to burn beg bugs and needs to be up to 120° F.

The bed bug heat treatments method remains the best solution compared to freezing that is below 4°F. As you can see, both the ways are tricky to achieve but not impossible.

Furthermore, it all depends on the equipment you use as using your hairdryer is not the solution. You can use CO² kits, or you can rent or invest in a high-pressure steamer to get the job done.

However, you will need to put an action plan in place:

  • By determining the severity of the bed bug problem using a flashlight.
  • You will need to take action giving the whole house a good cleaning using a vacuum and steamer.
  • Now all that is left is to give it a full week for it to take effect.

Furthermore, if you still find your results did not work, we recommend you call in a bed bug exterminator to help with the pest control problem. There are also pest control companies that allow renting machines to help eliminate bed bugs. If you can’t afford paying a pest management company, there are other various way of doing your own bed bug control, such as using diatomaceous earth or bug spray.

Falling Temperatures Do Not Necessarily Mean Fewer Insects

By Richard Levine

With record-breaking cold temperatures in much of the United States recently, newspaper headlines have suggested that the freezing weather this winter could mean fewer insects next spring. For example:

However, to borrow a quote from Mark Twain, reports of insect deaths have been greatly exaggerated. While it’s true that insects will die if exposed to very cold temperatures for prolonged periods of time, many are able to survive, depending on the insect and the circumstances. Fortunately, the journalists who wrote the articles above balanced the optimistic headlines with more realistic views in the actual text after doing their research and talking to entomologists.

It’s Déjà vu All Over Again …

This is nothing new, of course. In fact, two years ago we faced a very similar situation when an extraordinarily mild winter gave rise to headlines about how the warmer temperatures would mean greater insect populations come spring. Mosquitoes for example would thrive, the thinking went, because of the lack of freezing temperatures.

However, leaders of the Entomological Society of America said “Don’t Bug Out Over Warmer Weather” in a press release, explaining that lots of other factors affect insect populations besides temperatures.

“States like Alaska and Minnesota are famous for their brutally cold winters, and yet they are also known to have extremely active mosquito populations during the summer,” said 2012 ESA President Grayson Brown, who explained that mosquitoes are even more affected by the amount of rain during the spring, since they need water to lay their eggs.

ESA’s 2012 Vice President Robert Wiedenmann said that in some cases the warm winter could even cause harm. “Some insects that emerge earlier than normal because of warm temperatures may not find the appropriate food sources available and could starve,” he said. “Likewise, mild winters may favor the predatory or parasitic insects that help keep pests in check, and result in fewer pests. Insect ecology is affected by a number of factors and is not solely dependent on winter or spring temperatures.”

Long Story Short: It’s Complicated …

Which bring us to our current situation. While it’s true that extremely cold temperatures for prolonged periods of time can decrease insect populations, other factors are at play as well.

The Emerald Ash Borer (EAB) is a good example, since it has received so much press recently. Ironically, the recent cold spell could actually end up helping the EAB in certain areas because the freezing temperatures might harm EAB predators.

A few years ago, scientists in Michigan and other states began releasing tiny parasitoid wasps that help control the EAB by laying eggs into or on the EAB larvae.

“In general, parasitoids are more susceptible to stressors (e.g., pesticides, cold temperatures) than their hosts,” said Dr. Jian Duan, one of the scientists who has been rearing and releasing the wasps. “If this year’s cold temperature kills overwintering EAB larvae, it will surely kill the associated parasitoids — even more so than EAB.”

“Prolonged very cold temperatures can definitely kill off both EAB and the parasitoids, and the parasitoids appear to be less cold-hardy than the EAB themselves,” said Dr. Jonathan Lelito, another USDA researcher.

Dr. Lelito went on to explain that even in extremely cold regions like northern Minnesota and parts of Canada, where a significant portion of EABs may have died because of the cold, the effect will not extirpate the species completely.

“Even with 50% mortality, the populations will recover in a few years or so and the infestation will continue on,” he said. “But biological control is a long game. Occasional setbacks will occur, and the populations of both hosts and parasitoids will tend to oscillate through time anyway. The long-term goal is the establishment of a balance, and severe weather events are just a step in the long march, so to speak.”

The same holds true for other insects. Once again: It’s complicated.

Temperature Affects Stink Bugs More than Any Other Factors

A new study highlights the role of temperature and its interaction with urbanized areas and deciduous forests in influencing regional distribution and abundance of the stink bug.

Many things can affect the size and range of insect populations, including the climate, the availability of food sources, and the absence or presence of predators. But when it comes to certain stink bugs, researchers have found that temperature is the most important factor affecting regional distribution and abundance.

By using complex spatial and statistical analyses, entomologists from Maryland, Virginia, and Delaware determined that temperature is the primary driver of stink bug patterns, and they identified differences in thermal tolerances among native and invasive stink bugs.

The researchers conducted a survey of three stink bug pests — the invasive brown marmorated stink bug (BMSB) and two native insects, the green stink bug and the brown stink bug — in soybean fields in Maryland, Virginia, West Virginia, and Delaware. They found that the abundance of BMSB became lower as temperatures increased in June. In fact, no BMSBs were found in fields with average June temperatures that were higher than 23.5º C (74º F).

However, in contrast to the invasive BMSB, the abundance of the native stink bugs increased as temperatures rose.

However, people in these colder areas shouldn’t expect to be completely free of the BMSB because some warmer areas will still support them.

“Urbanized areas in these regions could support high abundance of BMSB by acting as ‘heat islands’ because cities tend to be warmer than rural areas,” Dr. Venugopal said. “Similarly, in the southeastern U.S. where warmer temperatures do not support large stink bug populations, BMSB might occur in higher abundance in the western mountains and Piedmont region, where it is cooler than the eastern coastal plains.”

This study is the first comprehensive large-scale survey that quantifies the interactive roles of the environment, resource availability, and distance from the source population on the pattern of distribution and abundance of stink bugs. Previous studies on BMSB examined these factors mostly in isolation.

Additionally, this study clearly identifies the spatial scale at which each of these factors operate, and it is the first to distinguish the roles of environmental and landscape factors on invasive versus native stink bugs.

“This study shows that despite the similarity among BMSB and native stink bugs in terms of their broad host-plant choice and stages of crops they prefer, their environmental and landscape associations are entirely different,” Dr. Venugopal said. “The native stink bugs have a tolerance for higher summer temperatures than BMSB, and that probably explains their broad distribution range in the U.S. However, BMSB is not able to tolerate very high summer temperatures. In pest management programs, similar group of pest species tend to get grouped together for similar strategies for management. Our results show that regional management strategies for stink bugs should incorporate these biological differences.”

What Is The Purpose Of Bed Bugs?

Purposes of Bed Bugs

There are several organisms and microorganisms that give scientists and laypeople alike pause to wonder as to their purpose in the circle of life. Examples of these organisms include insects such as cockroaches and bed bugs.

What purpose do Bed Bugs have?

Could the planet without them?

Do Bed Bugs contribute anything to the ecosystem or are they just simply parasites?

The Life Span of a Bed Bug

Bed bugs are wingless insects that are nocturnal and reddish-brown in color. They feed on the blood, specifically capillary blood, of humans and animals, making the question of what purpose do bed bugs have even harder to answer.

The life of a bed bug begins as an egg that resembles a piece of grain in appearance and is white in color. These eggs are laid in crevices with tight, tiny openings. A female bed bug will lay between 1 and 5 eggs in a day, and up to 500 in her lifetime. About two weeks after being laid, the eggs will hatch and baby bed bugs will emerge to immediately begin feeding on blood.

Upon reaching maturity, adult bed bugs will feed when food is available. They can go for months without feeding while lying in wait for its next food supply.

The lifespan of a bed bug typically lasts from four to six months, although if living in cool conditions they can survive for a year even with no food supply.

So What Purpose Do Bed Bugs Have?

Despite the overall consensus that the earth’s ecosystem could survive without bed bugs, some scientists insist that bed bugs are a food source for spiders, a very necessary element for making the planet habitable.

Bed bugs have evolved to live off of us, so they are here because we are here too. Like many species low on the food chain, bed bugs can nourish other organisms, such as centipedes. Animals like birds and toads, in turn, eat centipedes. Parasites can also get parasites, such as parasitic bacteria, which would bite the dust if their host went extinct.

Regardless of which side of the argument you may find yourself, it is important to remember that if you find yourself with a bed bug infestation, it is possible to get rid of them as well as their unhatched eggs. The best mode of action is to assess the problem, kill the bugs and their eggs, and possibly retreat to prevent recurrence.

Getting a bed bug infestation is certainly not the end of the world, but it will be some work to get rid of them. At the end of the day, I would like to think that bed bugs serve a purpose, even if we don’t see it or know it. Same thing can be said about roaches and they have existed for a long time as well. Bed Bugs at the least serve as a meal for another organism, bug, or critter.

Bed bug life stages

If you have a bed bug invasion at your home, it is important to know the stages of the bed bugs. So, you can learn how to fight with bed bugs.

What are bed bugs?

Bed bugs are commonly mistaken with other household insects like ticks, fleas, cockroaches or other carpet beetles.

To identify bed bugs, you should know basic physical properties of them. We posted about what bed bugs look like earlier: bedbugdetected.com/what-is-bed-bug-and-how-it-lives

They can be identified as 3 to 5 millimeters length, brownish, oval and flat shaped. They have no wings and can’t fly. Bed bugs also can’t jump like ticks. They can crawl rapidly like spiders and this is the way how they move to the walls or clothes.

Can you see bed bugs?

Yes, bed bugs can be seen by naked eye. They are 4 millimeters length in average and this is not enough for them to hide around.

The problem is that they do not prefer to move around at daylight. Bed bugs usually feed at night or early in the morning. Night helps them keeping from the eyes.

Bed bug life stages

A bed bug has three life stages: Egg, nymph and adult. So, let’s see the evolution of bed bugs in these stages.

First stage: Egg – Where do bed bugs lay eggs?

Egg may be defined as the first stage of a bed bug’s life. So, it is important to identify and find them. Bed bugs eggs are small, only about 1 mm length and has the size of a pinhead.

Bed bugs lay their eggs in to the cracks, holes or clothes and other stuff where they hide and is close to their feeding sources.

So, if you are looking for bed bug eggs; you should look every corner where they can hide: Furnitures, behind the pics, mattresses, beds, cracks, old stuff and clothes.

Bed bug eggs are sticky and glued to the surface. For example, cockroach eggs are rectangular, but bed bug eggs are oval-shaped.

The more blood a female beg bug can take, the greater number of eggs it can produce. The number of new eggs depends how the female bed bug feeds.

When a bed bugs lay eggs, the number of the male and female eggs will be equal, in a 1:1 ratio. Under normal conditions, most of the eggs (more than %90) survives and hatches successfully.

Second stage: Nymph (5 instars) – How fast they grow?

Nymph is the stage just after the hatch. They are about 1 to 5 mm length. A nymph will become very pale first, then after it feeds, they will be filled with blood and turn to red in color.

Nymph stage is not very short. If a nymph succeeds in feeding and the room temperature is suitable for them, about 70ᵒ F, they will get the next stage in about 35 days.

Nymph stage consists of five instars. They get bigger and bigger in every instar, from 1,5 mm to 4,5 mm at all. At the end of the fifth instar, they turn into an adult.

Recently hatched nymphs are tiny and they will not be able to travel to long distances. So if these tiny nymphs are away from a host, they will die because of dehydration before they access to their host.

Third stage: Adult – How long they live?

An adult bed bug is just like an apple seed. It sizes about 3 to 5 millimeters and up to 10 millimeters in some cases.

Adult bed bugs are dark red to brown due to their feeding facilities. While a bed bug is brownish, after its feeding, you can see it becoming reddish. A bed bug which hasn’t fed for a long time, may be for several months, will become lighter.

Adult bed bugs can survive without feeding for about 1 year which means you can still find some bed bugs when you move to a new house even a it was left vacant for several months or a year.

But recent researches show that bed bugs at homes in United States are not so tough and they usually die after a 2 or 3 months of hunger.

What bed bugs eat in every stage?

A bed bug only feeds by blood. But it must be a mammalian’s blood. So, they feed by human, dogs, cats or bats.

They don’t need to feed while they are eggs, at the first stage. In the second and third stage, where they are called as nymph and adults, they need to feed.

In other words, bed bugs do not eat, but they drink blood.
