Are Cockroaches Really That Dangerous?

Sure, cockroaches are not fun to look at, and the sound they make when you step on them is spine-chilling, but are they dangerous? Cockroaches are pests that can survive the apocalypse, they have played supporting roles in Hollywood flicks, and they have been around since the dawn of time. What could be so dangerous about that? Are cockroaches dangerous? Yes, but not in ways you may think.

5 Weird Facts about Cockroaches

Cockroaches are little pests that nightmares are made of. These five weird facts about cockroaches explain why:

There are more than 4,000 species of cockroaches worldwide.

Cockroaches can live a week without a head, and they can hold their breath for 20 minutes. Good luck flushing them out.

The largest cockroach is 6 inches long, which means it has a wingspan of nearly a foot. How’s that for a nightmare?

Cockroaches can run up to 3 miles per hour.

Cockroaches can survive more than 30 days without food.

Unfortunately, the weird facts about cockroaches are a few reasons why they are dangerous.

Dangers of Cockroaches

Cockroaches can adapt to any environment, and once they get comfortable, they thrive. This makes it difficult to control cockroach populations. Once cockroaches enter your home, they invade your cabinets, spread disease, and cause a distinct odor.

Remember when we said cockroaches can run up to 3 miles per hour? That is great speed for a marathon, but it’s terrible for your health. The faster a cockroach runs, the quicker they can spread disease throughout your home.

Diseases and infections caused by roaches include:

Cockroach droppings and infestations can also cause significant health risks to those with respiratory issues.

Cockroaches are a common household pest in New Zealand. While they are only a low-level health risk, cockroaches thrive in unhealthy environments and they can transmit a number of diseases.

All cockroaches are pests. The biggest cockroach pests in New Zealand are the American cockroach (Periplaneta americana) and the German cockroach (Blattella germanica).

Where cockroaches live

Cockroaches prefer damp, dark places. They are often found inside walls, behind household appliances and in cupboards.

Cockroaches thrive in warm and damp conditions and will dehydrate if the environment is too dry. However, they can survive in extreme conditions for short periods of time. Cockroaches can survive months without food and up to 4 weeks without water. This makes them very difficult to get rid of.

Health risks from cockroaches

Cockroaches can transmit diseases like dysentery, salmonella and diarrhoea. Their eating habits also expose humans to dangerous diseases. Cockroaches can eat a range of foods, from faecal matter to fresh food intended for people to eat. If cockroaches contaminate your food or the surfaces you use, you could get sick.

Preventing cockroach infestations

You can reduce your chances of a cockroach infestation by:

  • filling cracks in walls and foundations
  • keeping living areas dry and clean
  • disposing of rubbish
  • removing human waste and food waste from the home quickly and efficiently.

If you already have cockroaches, you might need to set baited traps or apply an insecticide to the area. Insecticides work best when applied to areas where cockroaches hide during the day or where they pass through at night time.

It is vital to keep your home clean and dry to stop you from getting cockroaches in the first place.

Cockroach lifecycle

Cockroaches undergo 3 stages of development: egg, nymph and adult.

The egg hatches into a nymph, which looks similar to the adult cockroach. The nymph then undergoes a series of moults before developing into a fully reproductive adult cockroach. The length of this process varies, and may take anywhere between a few weeks to a year to complete the cycle.

Female cockroaches are able to lay hundreds of eggs in their lifetime.

Do Cockroaches Carry Diseases?

Q. It is well known that mosquitoes, fleas, lice and ticks transmit human diseases, but what about cockroaches?

A. The proven health risks of cockroach infestation seem to be predominantly those of filth, food contamination and allergic asthma rather than direct transmission of disease, according to an extensive review of public health risks from all kinds of pests conducted by the World Health Organization.

Because many studies have found that cockroaches feed on human excrement and transfer or excrete pathogens, they have a strong secondary role in the spread of some diseases. But the W.H.O. review in 2008 concluded, “definitive evidence that cockroaches are vectors for human disease is still lacking.”

There is a substantial list of bacteria, funguses, molds and a couple of viruses that cockroaches can carry from place to place, not to mention an amoeba that causes dysentery, another parasite that causes giardiasis and the virus that causes polio.

But asthma caused by allergy to cockroaches themselves is the big public health concern. For example, a 2005 study found that children living in poorer urban areas in the United States were at greater risk of asthmatic illness from cockroach allergy than from allergies to dog or cat dander or to dust mite excretions.

are roaches dangerous for people? i mean, can they transmit a disease?

we have found them in our office ( in the kitchen) and we called the exterminator but it had no effect whatsoever, and most of them are still baby roaches 🙂 so now i am wondering if they could do any harm to our health cause i have heard that they have to do with asthma and other diseases, so please help as soon as possible! i am also worried that i could take them home in my purse or on my clothes and i always have to check which makes me really sick , TERRIBLE!

Some home owners are allergic to roaches, and the pests can contaminate food with certain bacterial diseases that result in food poisoning, dysentery, or diarrhea. Cockroaches can cause childhood asthma.

Yeah , i’ve read where they can cause problems with people who are allergic and asthmatic , and they carry bacteria. Have your boss or whoever go out and get a bottle of boric acid , sold at most hardware stores , etc. It’s not a «corrosive» type of acid , it is a powder (sometimes colored blue) and it will solve your problem in a week or two. you just sprinkle it under sinks , in cracks , behind counters , and anywhere you find the nasty bugs. It’s harmless to humans but it’s like kryptonite to the roaches , and it kills them good. It will kill other hiding roaches too cause they come out to feed off of dead roaches.

Put some ground bug spray on the entrances to your doors and on your windows,for some reason they won’t walk on it.

How Cockroaches Can Harm You

Posted on November 28th, 2016 by Knockout Pest Control

The natural reaction of someone who sees a cockroach is to scream and run away, which is completely understandable. While cockroaches may look harmless (even though they are creepy looking), they are actually quite dangerous. Unfortunately, even just the mere presence of a cockroach can cause harm to your health.

Allergies & Asthma
Not only can people with allergies be affected by cockroaches, but these pests can also cause allergies. Their bodies are covered with thousands of allergens that will more than likely cause an allergic reaction via skin rashes, sneezing, coughing, etc. For those who suffer from asthma, severe attacks can be experienced when cockroaches are present within the house or building.

Not all cockroaches will run after you with the intention of biting you. However, there are some cockroaches that will attempt to chomp at you. Some of these creepy crawlers will go after areas like fingernails, toes, and other parts of the body with soft skin. Even the smallest of nips can become a bite that causes an allergic reaction.

Contamination & Bacteria
Unfortunately, cockroaches will eat almost anything they come in contact with. Food, plants, glue, soap, upholstery, fecal matter — you name it, they eat it! After eating, cockroaches will regurgitate saliva that contains harmful bacterium such as Salmonella. Coming in contact with disease-causing bacteria will cause allergic reactions, while ingesting food that has been exposed to this bacteria will lead to food-poisoning and urinary tract infections.

Is a Bearded Dragon’s Bite Dangerous to Humans?

Bearded dragons have become quite popular as pets, even among children. However, many are still confused about whether these lizards can bite and about how dangerous they can be. This article provides some information on the same.

Bearded dragons have become quite popular as pets, even among children. However, many are still confused about whether these lizards can bite and about how dangerous they can be. This article provides some information on the same.

Generally, bearded dragons do not become aggressive. They do not attack even on being threatened. Instead of attacking, they just freeze, fluff their throat, and change color. Sometimes, they just prefer to run away.

A bearded dragon is actually a lizard, small to medium in size, having a well-muscled flat body. They belong to the genus of reptiles Pogona in the family Agamidae. This genus contains eight species, which are mostly referred to by the common name ‘bearded dragon’. However, the Central Bearded Dragon (scientific name: Pogona Vitticeps) is most referred to by this name and is also the most popular among others. In captivity, these lizards can live as long as 12 to 14 years.

Bearded dragons as pets

They are native to Australia, naturally and more commonly found in the desert regions. Introduced to the U. S. in the 1990s, they have gained popularity since then, mainly as pets. They have also become quite popular as pets among children. They are preferred as pets due to various reasons. They are gentle and quiet in nature, they are easy to take care of or manage, and they enjoy being handled. It is also quite safe to keep them as pets, mainly as they never attack or harm their owner. If at all they get aggressive, it is usually while hunting for food or with other animals.

When can they attack?

At times, when they are extremely stressed out or threatened, and in such cases, if they feel provoked, they may become aggressive. As a result of this, they may tend to attack or bite. This happens in very rare cases. Sometimes (mostly in case of pets), they tend to associate your finger with food and may bite your finger thinking of it as food.

What should you do?

In case you are bitten by a bearded dragon, remember to stay calm. Do not raise your hand instantly as the lizard may still remain on it and wriggle, which could make it worse. Instead, calmly support the lizard and using your free hand, gently move its jaws apart.

What could their bite cause?

Their bites may result in swelling and profuse bleeding, however, there would be no persistent or serious long-term consequences or side effects of any kind. Its bite may even hurt at times, however, the pain is nothing in comparison to that of a dog or a cat bite. Rather a scratch by a bearded dragon could result in a bigger wound as compared to its bite.

Are they poisonous?

Studies have revealed that bearded dragons produce venom. However, it is mild and harmless to humans and most other animals. Furthermore, it is believed that this venom may have been used by their ancestors in the past while hunting. On being bitten, there is no need to worry about getting poisoned. Moreover, it is said that the venom of some of their species like that of the Mexican bearded dragon has been used in the medical field. For example, it has been used in drugs for the control of diabetes. Studies also reveal that the presence of three new amino acids in lizard toxins can be used to treat heart diseases.

Risk of intestinal problems

Even though there is nothing to worry about on being bitten by a bearded dragon, there is one risk that may be a cause of concern. A bearded dragon’s mouth is known to carry salmonella bacteria that may be transferred to humans on being bitten. This may lead to serious intestinal problems. Thus, in such cases, it becomes necessary to scrub your hands with hot water and use an anti-bacterial soap before and after you have handled the lizard in order to avoid infection. In this case, you may even require a tetanus shot, if you have not taken it in the past 5 years.

Signs that they may bite

Recognizing the aggressive behavior of these lizards might prove beneficial to avoid such bites. Some signs include fluffing up of their throat and changing to a darker color tone, or a hissing sound. These are just some signs that have been commonly observed in aggressive lizards. On observation of such signs, it is better that you don’t disturb the lizard. If you notice the signs, while handling, gently place the lizard back into its habitat. It is said that in case of pets, handling them in spite of such aggressive signs may strengthen the bond between you and your pet, however, you need to wear gloves (gardening gloves) for protection.

We can conclude that although a bearded dragon’s bite is not dangerous, it does require attention and minor treatment.
