Droppings and remains from cockroaches may cause an allergic reaction and asthma symptoms in some people.

Although cockroaches scurry away when the kitchen lights come on, they leave behind droppings in the form of tiny pellets. The feces contain a digestive enzyme that is thought to be an allergen. And if that is not enough, consider this: Dead roach body parts, which are known to be allergens, adhere to dust particles. These, in turn, become airborne and can cause an allergic reaction when they enter the lungs, eyes and nose. Extermination can increase the problem because there will be more dead body parts in the dust. For allergy-friendly roach control, it's best to use traps.
