Allergens present in the feces of the German cockroach can become airborne along with normal house dust, and can also be inhaled or ingested when in contact with food.  The German cockroach is common in warm climates and where heating is maintained in houses and apartments, and particularly common in inner city apartments.  This allergen can be as problematic for asthma patients as dust mites.  Control measures include the following:

• Store food in tightly sealed containers.
• Do not leave food or unwashed dishes out.
• Empty garbage containers frequently, especially if they contain food scraps.
• Limit food in kitchen.
• Use professional pest control services to eradicate insects in cases of severe infestation.
