Cockroaches aren’t just unsightly pests. They can also be an allergy trigger. Their saliva, feces, and shedding body parts can trigger asthma and allergies. These allergens act like dust mites and make symptoms worse when they are kicked in the air. The National Pest Management Association reports that 63% of United States homes contain this allergen. But don’t worry, our allergist can evaluate if you are allergic to cockroaches.
