While the change of seasons may offer some relief for those suffering from seasonal allergy symptoms, indoor allergens unfortunately exist year-round in some form or another. One of the lesser-known indoor allergens also just so happens to come from everyone’s least-favorite houseguests: cockroaches.

How Common Is Cockroach Allergy?

Cockroaches are not only pests but also major contributors to allergy symptoms. 

Studies have shown that cockroaches are a common source of indoor allergens worldwide. Furthermore, health experts have found a link between cockroach allergies and asthma.

One study found that 40% to 60% of people with asthma in urban environments possess IgE antibodies for cockroaches. IgE antibodies trigger immune system responses toward allergens — they’re basically what cause allergies. 

Cause of Cockroach Allergies

In terms of what causes a cockroach allergy, the answer is simple. Cockroaches exist (in some places more than others), and their bodies, saliva and waste contain a highly allergic protein, even in their dead exoskeletons.

Cockroach Allergy Symptoms

Additionally, studies have shown prolonged exposure to allergens, such as those cockroaches produce, causes asthma in some children. So if you have asthma, cockroaches are a potential trigger. If you don’t have asthma but are allergic to cockroaches, you’re at increased risk of developing the condition, especially as a child.

Other cockroach allergy symptoms may include the following:

  • Nasal congestion
  • Coughing
  • Rash
  • Sinus infection
  • Wheezing
  • Ear infection

If you suffer from year-round allergy symptoms, it’s possible that a cockroach allergy is to blame. And for many people suffering from an allergy to cockroaches, their symptoms can become chronic, occurring no matter the season.

Cockroach Allergy Treatment

At the Pasha Snoring and Sinus Center, we rely on allergy tests to determine your sensitivity to allergens. If a physician finds you’re allergic to cockroaches, you can take various steps to relieve your symptoms. 


The first step is avoidance. However, cockroaches aren’t going anywhere, and even when they die, their carcasses become dust components. In fact, many people who have “dust allergies” actually have a cockroach allergy.

Dust Protectors

In the case of cockroach allergies, avoidance involves covering furniture with dust protectors. Don’t worry — dust protectors don’t have to be the crinkly vinyl covers your grandparent used. These days, you can find surprisingly stylish cloth covers with tiny pores too small for dust to travel through.

Many people may consider antihistamines as a treatment for a cockroach allergy. However, antihistamine medications have side effects like dryness and do not offer long-term results. 

HEPA Filters

Another step you can take is purchasing high efficiency particulate air (HEPA) filters to help purify the air in your house. HEPA filters can remove 99.97% of airborne particles with a size of 0.3 microns.

Pest Control Tactics

It also wouldn’t hurt to step up your pest control game — but that doesn’t mean spraying harmful pesticides over every inch of your house. We’re talking about more meaningful (and safer) actions. Here are a few to start with: 

  • Keeping food in sealed containers
  • Reducing clutter around the house 
  • Generally polishing your housekeeping routine


Avoidance isn’t always effective for cockroach allergies, especially in urban environments where a high human population supports much higher bug populations. If avoidance doesn’t work for you, immunotherapy is the remaining option.

Immunotherapy is by far the gold standard for a long-term solution. Allergy specialists expose you to allergy triggers (e.g., pollen, dust, mold) without triggering symptoms by “building up” your immunity. 

The Pasha Snoring and Sinus Center is unique in that we offer different immunotherapy methods, such as shots and oral drops. Both modalities allow you to administer your own at-home immunotherapy.
