Cockroach allergies are remarkably common, and some researchers believe the incidence is rising. One-third of people with other documented allergies are sensitive to cockroaches, but so are up to 12 percent of individuals without any other known allergies. Cockroach allergies may be dangerous to people with asthma, as exposure may cause severe attacks in over half of those diagnosed. Even if you've never seen a cockroach in your home, the allergen may be present.
It is not necessarily a reflection of the cleanliness of your home. Cockroaches live in walls and other places you cannot see or easily clean. The bugs thrive in moist, humid climates, and abide in cracks, crevices and spaces between walls.
Cockroach allergens behave like dust mite allergens and stick to heavier particles that quickly settle. These allergens do not remain airborne for long.
Activities like vacuuming may stir up allergens that have settled in dust or fabrics. The most common way to inhale cockroach allergen is to breathe in dust or allergens that have collected in pillows, bedding or other dust-trapping fabrics. Not only do cockroach allergens trigger asthma and allergies, researchers are exploring evidence that early exposure to cockroach allergen can actually cause asthma to develop in preschool-aged children. Cockroaches don't need to be present for there to be cockroach allergen in your home.
One in five homes with no history of cockroach infestation has a significant level of allergen in dust and fabrics. Allergen concentrations are generally highest in kitchen areas where there is plenty of food and water to support cockroach infestations.
However, bedroom allergen concentrations may be more relevant. People spend significant time in close contact with their pillow, where they can inhale the allergens that have settled into bedding.
Socioeconomically disadvantaged people are more likely to be exposed and allergic to cockroach allergens, whether they live in a city or rural area. Cockroach allergens spread widely throughout homes, schools and other public places. Simple precautions can protect individuals who are particularly sensitive to cockroach allergens.

Atopy is typically associated with asthma, allergic rhinitis similar to hay fever and atopic dermatitis. Allergens from cockroaches have been shown to trigger all three of these reactions. Asthma attacks make it difficult for a person to breathe. These attacks can be fatal, so the lung disease must be treated by a doctor. According to the University of Colorado Health website, other symptoms experienced by those who are allergic to cockroaches include chronic stuffy nose, itchy eyes, repetitive sneezing, postnasal drip, sensitivity to light, frequent sinus and ear infections, decreased sense of taste and smell, wheezing, chronic coughing and a skin rash atopic dermatitis.
