Why Do Cockroaches Cause Allergies?

No one wants to be around pests and no one wants pests in their home. But, is it actually possible to be allergic to pests? Yes, believe it or not, cockroaches cause allergies. But why does this happen and what can you do about it?


Cockroaches cause allergies: what you need to know

The reason why this happens is simply because the bodies of cockroaches contain allergens. These are found in the discarded skin of cockroaches. These pests are constantly shedding their skin and wings. These end up all over your home and this is why cockroaches cause allergies. These allergens are also found in the egg casings of cockroaches.

This is actually a good way to determine if you have cockroaches in your home. If you’re experiencing allergic reactions, and cannot find the cause, then it may be cockroaches. This can be true, even if you don’t think that you have cockroaches that can pose a danger.

These pests are extremely good at hiding away, and can live undetected for years. They may even be in places where you cannot get to, such as inside of crawlspaces and pipes. So, if you’re having mystery allergic reactions, don’t rule out cockroaches.

What sort of allergies are caused by cockroaches?

What’s also interesting is that you may not necessarily realise that cockroaches cause allergies. Many people do not know that they are allergic to cockroaches. To determine this, you’ll have to look at the symptoms.

These are almost exactly the same as a flu or cold. You’ll experience things like a stuffy head, dripping nose, sneezing, coughing, and other flu-like symptoms. Your skin may also break out in a rash.

What you need to do is rule out everything else. If you cannot pinpoint the source of your allergic reaction, then maybe it’s cockroaches. Also notice what happens when you’re out of the house for a while. Do your allergies clear up, or do they persist? What you should do next is determine if you do actually have cockroaches.

You can do this by hiring a pest control company. They can do an inspection and see what’s going on. You can also look for the kitchen invading cockroaches yourself. Search in areas which are dark and damp, and also close to sources of food. This will include places like kitchen and bathroom cupboards. Also look beneath large appliances like your fridge and stove.

If you do find cockroaches, then clear out the area where they live and breed. Remove all sources of damp and water. You’ll also need to keep your home clean and remove all sources of food for the cockroaches.


In addition, vacuum everywhere, so that you can clean up all shed skin. Remember, cockroaches cause allergies, but it’s their skin that does this, not the cockroaches themselves. Some people can eliminate cockroaches with DIY methods, but usually pest control services are needed.
