Cockroach Allergies

Allergies often accompany asthma. They are separable, although many asthmatics experience flares because of seasonal allergies or other allergen triggers. Interestingly, a common allergen is not often discussed, which most people find quite gross. Most of our allergens would be exterminated if they were exposed to a nuclear blast, however, this one allegedly wouldn’t? I’m talking, of course, about cockroaches. The notoriously evasive and resilient pests that are a trigger for many people who experience chronic allergies.


These pests are a worldwide issue. In fact, there are about 4,000 known species of cockroach, spread across every continent--even Antarctica. Roaches are most commonly found in cities, with as high as 85% of urban homes testing positive for cockroach allergens.1 There is no environment that does not host the roach; even radioactive areas have an infestation. So, moving away from them is not quite like moving away from a pollen allergy.

The allergens of cockroach are a serious issue for asthmatics and are a more common trigger than most would expect. There are 12 known heterogeneous protein structures that are produced by the saliva, body, and waste of cockroaches.1 This can make it difficult to create allergy sensitization treatments and creates levels of complexity for researchers.

There are some ways that you can limit your exposure to cockroaches and their allergens. Being proactive is never a bad idea.

  • Keep food containers and garbage cans sealed.

Cockroaches are undesirable but they are everywhere, literally. As people with asthma, if we have an allergy to the common roach, it will affect us more than most others. Talk to a doctor if you suspect a cockroach allergy so you can make an appointment to confirm. Take action towards limiting your exposure to the allergen as well by being proactive.
