We have been despising them while living in their fear. But like other insects, do cockroaches bite? And if they do, what do the bites look like? Keep reading to find out.

Do Cockroaches Bite?

The answer is yes; they do bite. But it isn’t very common.

The reason for that is that cockroaches like to feast on sweet and starchy things like sugar, milk, cheese, grain products, sweetened chocolate, pastries, etc. This is why they are commonly found in the kitchen including the microwave, dishwasher, and refrigerator.

But, human bites can occur when the population has grown to the point of outgrowing food resources. In that case, when there is less food, roaches will seek out other food sources, and in rare cases, the human flesh.

There are records of cockroaches biting humans, but they are infrequent because it is scarce that a roach will resort to wanting to eat human flesh. But they can indeed do that, both from a corpse or a living person.

What Does a Cockroach Bite Look Like?

A cockroach bite looks like a red bump that is raised on the skin. Like mosquito bites, people can react differently where the bite area may be larger and puff up more on some individuals where it may not be too noticeable on others.

Generally, they look pretty similar to mosquito bites, but the difference is that the former can scab over.

Another visible difference is that mosquito bites are smaller, but cockroach bites are more significant than that.

Is a Cockroach Bite Similar to Other Insect Bites?

Not really. It may look like a mosquito bite, but it will be more prominent in size. Also, it might scab over or produce allergic reactions like rashes or lesions, etc. It may even cause a severe asthma attack in certain individuals.

Is a Cockroach Bite Treatable?

Yes, cockroach bites are treatable. Most of the time, you can just treat it with simple home remedies. If your symptoms continue to get worse, you would want to seek professional help right away to get proper treatment.

How to Treat a Cockroach Bite

The first step is to disinfect the area where the bite is located thoroughly. To do that, rinse the skin with warm water and plenty of soap.

After that is done, you can use other remedies. For example, applying an ice pack or cold compress can help with the swelling and relieve you from itching. You can also use lemon juice or an antiseptic.

Lemon juice is very effective against the itching sensation. In fact, any citrus fruit will do.

For antiseptic, you can either buy ethyl alcohol or hydrogen peroxide, depending upon your skin reaction when it comes into contact with it. To deal with the pain, you can buy over-the-counter medicine from the nearest pharmacy.

What Are the Chances of a Cockroach Biting You?

Very low, or almost next to none. Cockroaches may get plenty of food, so they won’t resort to biting you. Even if they are desperate enough, they would prefer dead skin over healthier, fresh skin.

But if a cockroach bites you, that is a clear sign of a vast roach infestation in your home (or you are the cleanest person on earth and they have no access to food).

This is because now the population of roaches has overgrown the food resources available, so in desperation, they resorted to eating human flesh. After treating the bite, you should probably do something to deal with it ASAP.
