Besides the fact that the presence of cockroaches in the apartment is simply unpleasant, they can also bite, and quite noticeably - very few people know about this.
Agree, in the modern century it is difficult to imagine an environment in which cockroaches can bite people. Nevertheless, there is incontrovertible evidence that they can not only eat the surface of the skin in some places, but also seriously damage the epidermis, even wounds, blisters and skin erosions.
You can often find a denial of the fact that domestic cockroaches bite. This is indeed a rather rare phenomenon, because in any home for these parasites there will always be sources of food in more or less free access.
However, back in the 60s of the last century, American scientists Roth and Willis were convincingly confirmed about 20 cases in which cockroaches bit through and gnawed small particles of delicate skin on the neck, elbows, eyelids, fingers in sleeping people, especially in children. In strong sleeping small children, they could eat parts of the skin, even in the area of the nose and lips, causing infection in the wound, as well as nibble the cilia on the eyelids.
Over the bite of a cockroach, a crust usually occurs, under which the skin becomes inflamed and does not heal for a long time.
It must be said that these parasites have a well-organized mouth apparatus for eating and nibbling everything that suits them. It includes not only powerful upper and lower jaws, but also hard chitin “lips”, as well as a similarity of tongue, also consisting of chitin, so it is not surprising that not only exotic species, but also domestic cockroaches can bite a person rather deeply.
Of course, cases of cockroach bites are not as common as mosquito bites, flies, ticks and bedbugs, and are largely due to lack of water, without which, as you know, cockroaches can live only a few days. In search of water, cockroaches can bite people when they are asleep and almost immobilized without posing any danger.
Cockroaches try to find water in food debris around the mouth, in saliva and in tears around the eyes. Also, these insects bite (more precisely, eat the skin) sleeping people in cases where their populations become so largethat free food is not enough for them to live. Such cases were repeatedly recorded on ships, when the sailors had to sleep in gloves due to the fact that ordinary cockroaches gnawed the skin on their finger tips around the nails.
Sadly, cockroach bites occur today, in the 21st century, and this happens not only in neglected dwellings, as one might immediately think, and sometimes even in quite decent places like hospitals, hostels, and kindergartens.
Feedback:
In our hostel a lot of cockroaches. In our block we tried to destroy them with various means (from boric acid to aerosols against cockroaches). But on our floor there are students who do not fight at all with these insects, bring food to the block, do not take out the garbage for a long time.
It may seem ridiculous and even fantastic, but lately cockroaches have also begun to bite. In the mornings I see on my body in the area of the fingers and on the face the most real wounds that do not heal for a long time. Before going to bed, she constantly began to be smeared with an anti-mosquito remedy, and, going to bed, I carefully examine it every time for the presence of crumbs.
When I tell my acquaintances about it, in response I hear banterings like the fact that cockroaches have now disappeared altogether, and assurances that bed bugs or ticks cause me to bite. However, once I saw with my own eyes how they crawl over the sleeping girlfriend at night. In the morning, on her body in places where cockroaches crawled, we found small wounds and reddening of the skin. What other steps to take, just do not know anymore!
Cockroach bite hazard
Cockroaches in saliva and other secretions contain a special protein tropomyosin, provoking the occurrence of allergic attacks, respectively, after the cockroaches have bitten a person, he may have multiple allergic reactions, starting urticaria and ending with an asthmatic attack. However, these are not the only possible effects of cockroach bites:
- After weak or small bites, insect-eaten places can become inflamed or covered with a long-standing crust or scar, allergic skin reactions such as redness, irritation and various dermatitis can occur.
- There is a possibility of entering into an open wound (even a small one) of bacteria on cockroach,among which may be causative agents of dysentery or tuberculosis.
- It was all about red cockroaches. But after numerous bites of the American and Egyptian cockroaches, accompanied by severe eating of the epidermis (more typical of people in tropical countries), skin erosion, various blisters and papules can occur, which are accompanied by severe pain, purulent crusts and other pococcal diseases. At the same time, pyoderma (the so-called skin diseases accompanied by abscesses) may, of course, have a rapid course and be completed in a couple of days, but in people with weakened immunity they are able to turn into chronic poorly healing ulcers.
Myths about cockroach bites
In addition to the very real negative effects of cockroach bites, some of the myths associated with these common insects are very popular among the people:
Myth number 1. Due to the fact that these parasites are not afraid of radiation, but accumulate it in themselves, a cockroach bite can cause a mutation.
These insects can indeed withstand radiation exposure that is 15 times higher than the level dangerous for humans, but there can be no talk of any accumulation of radiation, and even more so of mutation transmitted through a bite.
Myth number 2.A cockroach bite can cause anaphylactic shock. Allergy in the form of pruritus, tearing, and even shortness of breath is a fairly common reaction to specific substances found in the saliva of a blood-sucking insect (for example, a mosquito) or in the venom of insects such as a wasp or a bee. In some cases, even the development of anaphylactic shock is possible.
Since cockroaches as a biological species do not belong to the blood-sucking, then the probability of anaphylactic shock on a bite is quite low.
However, a variety of cockroach excretions (chitin cover discharged during shedding, saliva, feces) themselves can cause a strong allergic attack.
Myth number 3. Human hair, nails and earwax are the favorite foods of cockroaches. Cockroaches are known to be omnivorous, and this myth appeared, obviously, because of the cases of sailors who, during a long voyage, suffered from numerous bites in the area around the ears, eyes, fingertips.
On the other hand, with a large gathering of cockroaches in the room, one of them may well head in search of food directly into the human auricle.Not being able to crawl back, he can create a dangerous health situation, causing pain to a person and creating a risk of damage to the eardrum.
How to treat a cockroach bite?
If, in the morning, traces of bites are found on the body, then first we must determine which insect has left them, and then turn to a dermatologist for the appropriate treatment.
Most often, traces on the skin in the form of a path appear from bedbugs, in addition, the places of bites of blood-sicking insects (bugs, ticks) itch much because of the special substances in their saliva. If there are doubts that it is biting domestic cockroaches, you should pay attention to whether the bite looks like a small open wound in places where the skin is more tender compared to other parts of the body. You can even compare this wound with photos of cockroach bites on the Internet for greater certainty.
In any case, it is necessary to treat the wound with an antiseptic type of hydrogen peroxide to prevent infection, and then use an ointment that removes skin irritation.
From popular recipes: in order to soothe the inflamed skin after insect bites, use gruel from plantain or raw potatoes, lotions from black or green tea.
For allergy sufferers, especially those who have already experienced an allergy to insect bites, it is advisable to take a suitable antihistamine.
Measures for the prevention and control of cockroaches
The most effective means fighting domestic cockroaches will be the destruction of their modern industrial products.
If we are talking about your own apartment or private house, then to prevent the penetration of parasites into the bedroom and other residential areas, you should make it a rule not to eat food and any drinks outside the kitchen, not to allow water stagnation in flower pots.
If the cockroaches were bred in a dormitory, you will have to combine the efforts of several blocks, and sometimes the whole floor for the destruction of uninvited guests. You can use several forms of industrial products at once, including various insecticidal action traps and gels.

I have no cockroaches, but crawling from a neighbor. I’m harassing myself, but after two days I find them again. My neighbor resists categorically. And the whole entrance on the ears. What to do? Maybe someone will tell?
I found houses on the wall of a large black cockroach and wanted to kill him, but it didn’t work, I ran away. Later, I went to bed with the TV on, the blanket was ajar on my back. And someone bit me so hard, it didn’t look like a mosquito. As a result, I found two red spots (pits) on my back. It seemed to me that the cockroaches avenged my revenge for the black cockroach - conspired.
I bought a blocker (balm in a syringe) for 2-3 months enough and economical. It costs about 34 rubles. There are in stores. At the same time, there should be no water sources - they take a rest. Found in a dog bowl with water and inside the bath.
Soon I would go crazy, the cockroaches overcame. I tried to remove them with all sorts of syringes and poison with boric acid, there is no water at home. It does not help, so they also began to bite. Please advise what to do?
Fought with cockroaches in the kitchen, so they went to live in a room, we do not eat in the room, there are no crumbs, they feed on glue in furniture and oil on the fasteners of the furniture door. I found empty eggs in the room, which means that a generation hatched, which does not even know about the existence of the kitchen and lives in peace and breeding in the room.
In the apartment we got cockroaches. Baited - does not help! They also began to bite. What to do? Help.
Bliiin, I was also bitten at a party ... And I saw him on my arm, I can not go to bed now.
Long struggled with reptiles, no expensive tool did not help. I bought a dohlox gel for 32 rubles. - from the first time they died.
I was bitten by a cockroach in my finger and I was worried about what would happen to me and how to remove the itch from the bite, and whether it had an effect on the body. Thanks for the tips!
We have no cockroaches. But our neighbor is drunk and homeless. From it, they climb a pair of pieces. How and what to fight with them, so that they do not want to climb to us?
I will share my advice, it works 100% and not for the squeamish. Buy boric acid in the pharmacy, it says powder, but there are small granules ... Take a coffee grinder,grind to the state of flour our acid and in some vessel, for example, the lid of a can. We remove to a place accessible to you so that if necessary you can immediately take a pinch. Usually you see them in the morning, and so, you don’t need to kill him, but just sprinkle it to get albino)) And let him run. If the cockroach is on a vertical surface, press down a little, but do not kill, and also dust it, it will heat up and run off into its mink. The fact is that boric acid causes terrible itching in cockroaches, and a sprinkled cockroach in its mink infects its fellows. As a result: after about a week of constant hunting, you will be pleasantly surprised by the lack of data on the beasts in your apartment ... Until the neighbor slacks off)) By the way, there is still good advice - cockroaches are very smart, before they move to permanent residence, they send a scout . If you do not have cockroaches and you suddenly saw one, hurt yourself in a tortilla and kill him, otherwise stock up on boric acid, because he will return to his people and tell you how good you are))
Oh, the same story, with only eleven. Sleep there is unbearable.And the nurses still say to me: there is nothing terrible here, they are everywhere, they say, get used to the situation. And the fact that the child was bitten is nonsense, not their children are there ... An hour ago, when I came home, I still cannot move away from what I saw.
Yes. Cockroaches really bite. A specialist was called yesterday and he treated the entire apartment with chemicals. Most of them died. But just that something had bitten me by the thigh, and, turning round, I saw that a cockroach was sitting on my thigh. I killed him. Now I have a blister on my leg, like a mosquito bite, only wide. Not itching, but discomfort when I touch it, and slight numbness at the site of the bite. Now I have experienced it myself and now I’m 100% sure that cockroaches really bite.
From strong itching and swelling from a bite, garlic helped me well. Grate with garlic or squeeze out a little and smear well with cream, so as not to make a burn. At hand was "Bepanten", bribed his "wound-healing and antiseptic" effect. In the morning there was only a hole from the bite, itching disappeared in a few minutes, swelling disappeared during the night.
I was bitten by a cockroach on my leg, I combed it, and now the floor of the foot was swollen. How to treat, tell me?
I am afraid that cockroaches are not something that people eat ... But I heard that they willingly eat both wires and plastic, if they have nothing to eat. Well, that did not eat the laptop! Well, 3 years ago there was a case: I bought a cheap poison - gel. Placed in the places of accumulation of these parasites cartons with poison, they devoured, called their "friends", they also ate muck. For 4 days they disappeared, but one thing: the corpses lay around: \ I was not bitten. Dad brought cockroaches in a suitcase ...
But these creatures in 3 years now again.
Horrible insects. Of course, they didn’t bite me, and in general, I heard about it for the first time from a friend, but now it’s very difficult to get rid of them. They even bought this thing with radiation waves. The first day something began to swarm, and on the second, as if nothing had happened, only my head ached. The only thing that cockroaches fear is frost, like other insects. You just have to open the windows in the winter, create a tannery, so to speak, and leave for a while. Just do not try to throw away the corpses in the trash, they can wake up and start crawling again.
At night, I got up to drink water and saw a cockroach behind the stove; he managed to leave, but somehow I didn’t feel at ease. We will be poisoning in all sorts of ways!
I was bitten by a cockroach by the neck, and so far there is nothing.
I was bitten by a cockroach - in the morning I got up, something was burning my side. There was redness and itching, so I treated with 3% peroxide and smeared it with antimicrobial agent (streptocide). Redness was very painful and kept for a long time. Just do not scratch, and so everything went.
Cockroaches were bred from neighbors ... Mom says: "Dichlorvos". And I think it will not help. But we have a small child.
We also have a terrible case: cockroaches crawling over children, I do not sleep at night, I urinate them! Now I lie, the red-haired cockroach crawls on the bed, and the eldest son has a bite on the side, like an eaten skin. Scratches him almost to the blood. What to do, how to poison these creatures?
I beg your pardon, wet them - who is this? Children or cockroaches?
The day before yesterday I stayed with a friend, and these creatures (not friends, but cockroaches — I will call them maxims in the future) bit my elbows! Nothing itches. I don't like maxims at all.But until that moment I didn’t care about them! But the bites of the maxims burn, like an abrasion.
Not Maxims but Stasiki call them. Today I have 15 bites per night, itching is impossible. By the way, I advise everyone to Agran. There was no year, although we live in a hostel, there are many of them in the common bath. See, a year later she brought to the room on plates when she was washing. Again, I will handle this tool.
Lord, 10 years have not seen cockroaches! I thought they were extinct, but no, you bastards! And in the apartment appeared huge black cockroaches. What are they scary and arrogant. Traps do not help, you have to buy an even stronger tool. I also wrote an ad for the whole staircase, so that everyone would unleash everyone on the weekend. They say, otherwise nothing.
Cockroaches can get into the ear, very afraid ...
Yes, cockroaches bite. Bites appeared on the body - at first I thought it was mosquitoes, but one night I watched a movie and saw that it was crawling! Help, how to get rid of them?
There were no cockroaches for 10 years, but after they were poisoned in the next house where the store is located, I simply did not believethat cockroaches can go in the direction of our house - 5-10 cm wide and over the entire length of 20 meters. Among white day! Creatures! Now I can not get rid of them. Give advice. Dichlorvos and syringe with gel do not help!
I had strange events one day. August, when I ride the bus, I suddenly feel that someone is biting into the arm just below the elbow (on the back side). I mechanically take off - and oh, horror, cockroach! I threw him off. At the dacha I am going to bed, I feel that again approximately in the same place someone is crawling. Grab and throw on the floor through a sleeping husband. I get up quickly, turn on the light, but late, no one is gone. I think he was a mustache, the benefit is not bitten. It just became creepy - one day it is. Dragged to the country with a microwave, which was previously at home. Reptiles bred very quickly.
