You don’t need to be convinced that getting rid of cockroaches is vitally important. But there is more cause for concern than just the ick factor with these unwelcome pests; they are one of the biggest culprits around when it comes to causing allergies and asthma, especially in children.
Those living in low-income and urban housing are especially at risk due to the close quarters and challenges in maintaining an Integrated Pest Management (IPM) plan.
Cockroaches are not just a nuisance in your home. If you’ve ever wondered, “Can you be allergic to cockroaches?” — the answer is yes. Cockroach allergens can cause sneezing, itchy skin, and even worsen other conditions like asthma. Understanding cockroach allergies and how to prevent infestations can help you breathe easier and maintain a healthier home.
Can Cockroaches Cause Allergies?
Yes, cockroaches can cause allergies. Their droppings, body parts, and saliva contain proteins that act as allergens, triggering reactions in some people. These allergens become airborne when these pests scurry around, breaking down into tiny particles that one can easily come into contact with or inhale. The most common species responsible for allergic reactions is the German cockroach, but the American cockroach and other types can also cause allergies.
Those most at risk include people living in inner-city areas, individuals with seasonal allergies, or anyone already sensitive to dust mites or other indoor allergens. Cockroach exposure is linked to allergic rhinitis and can aggravate respiratory diseases, such as asthma, particularly in children.

How Do Cockroach Allergies Develop?
Cockroach allergens become a problem when there’s an infestation in your home. These pests leave behind waste and detritus that can accumulate, leading to higher concentrations and greater exposure. When proteins from cockroach allergens found in saliva, feces, and other body parts enter your system, your immune system may overreact, causing sensitization and allergic reactions over time.
The higher the level of infestation, the more problematic these symptoms become, which is why it’s essential to address cockroach problems promptly.
Symptoms of Cockroach Allergies
Common cockroach allergy symptoms include:
- Sneezing
- Runny nose
- Nasal congestion
- Watery eyes
- Itchy skin or rashes (commonly known as “roach rash”)
Severe reactions can include post-nasal drip and allergic rhinitis, which can mimic cold symptoms. If you suspect a cockroach allergy, it’s important to visit your healthcare provider to seek medical advice for proper allergy testing and a treatment plan as soon as possible.
How Do You Get Diagnosed with This Type of Allergy?
If you suspect you have a cockroach allergy, the best way to confirm it is by seeing an allergist. They may perform one of the following tests to confirm this type of allergy:
- Skin Prick Test – A small amount of cockroach allergen extract is placed on your skin, usually on your forearm or back. The skin is then lightly pricked to allow the allergen to enter. If you’re allergic, you’ll develop a red, itchy bump within 15–20 minutes.
- Blood Test – This test measures the levels of cockroach-specific immunoglobulin E (IgE) antibodies in your blood. High IgE levels indicate an allergic reaction.
Managing and Treating Cockroach Allergies
If you have a cockroach allergy, there are several ways to manage it. Over-the-counter antihistamines, decongestants, and nasal corticosteroids (nasal sprays) may help you manage symptoms. In more severe cases, allergen immunotherapy (allergy shots) might be recommended for long-term relief.
Homeopathic remedies like eucalyptus or peppermint oil may help relieve symptoms like runny noses and stuffiness, but the problem will likely persist.
The most effective way to prevent allergic reactions is by addressing the root of the problem—cockroach infestations. Getting rid of cockroaches in your home is essential for reducing allergen exposure.
Tips to Prevent Cockroach Infestations (and Reduce Allergens!)
Preventing cockroaches from entering your home in the first place is the best way to avoid allergy triggers. Here are some proactive steps you can take:
Keep It Clean: The Power of a Clean Home
Many of the little household chores you’re already doing really do have a big impact on the presence of pests in your home. However, extreme diligence and attention to detail may be needed when trying to eradicate the most persistent of pests.
Cockroaches are attracted to food crumbs and moisture. To keep them out, start in the kitchen. Sweep and mop regularly, and don’t overlook the areas under cupboards or behind appliances like your stove or fridge. Make it a point to wash dirty dishes promptly and wipe down counters to remove food particles. Lastly, remember to empty trash bins regularly to prevent building up of food waste. Don’t forget to store pet food in sealed containers and clean up any spills immediately.
Deep cleaning areas where cockroaches tend to hide, like under appliances, in basements, and behind cabinets, will further help reduce allergen buildup. These pests are also drawn to moisture, so focus on areas like the kitchen, bathroom, and laundry room and make sure proper ventilation is possible to avoid excess moisture.
Check out the signs of a cockroach infestation so you can act quickly.
Seal Entry Points: Keep Cockroaches Out
Cockroaches can enter your home through the smallest cracks and crevices. Here’s how to seal them out:
- Use caulk or weatherstripping to close up small cracks around windows, doors, and pipes.
- Pay special attention to cabinets, sinks, and bathrooms, which are prime entry points for these pests.
- Regularly inspect basements, crawl spaces, and areas with plumbing for gaps or leaks.
They may also find their way into your homes by hitchhiking in delivery boxes or secondhand items.
By sealing off these entry points, carefully inspecting the items you bring into your home, and a little extra vigilance, you can significantly reduce the chance of a cockroach infestation.
