Cockroach Feces

Cockroaches leave feces or droppings that are easily identifiable. The feces of small cockroaches are black and resemble ground coffee or black pepper. Larger cockroaches leave black or brown droppings which are cylindrical in shape and have ridges down the side.

German, American and Oriental cockroaches’ feces and saliva contain problematic proteins and allergens, which may trigger asthma attacks. In fact, in densely populated cities, scientists have identified a correlation between roach presence and the incidence of asthma. Many studies are being conducted to determine the accuracy of this correlation. In one such study conducted in 2005 by the United States National Institute of Environmental Health Sciences and the United States National Institute of Allergy and Infectious Diseases (NIAID) it was proven that among inner city children, cockroach allergens worsen asthma symptoms more than other triggers. However, despite this data, according to a study conducted by the National Pest Management Association (NPMA), only 10 percent of homeowners believe that cockroaches pose health threats to their families.

Should you find cockroach feces in your house, vacuuming and cleaning affected areas with warm water and soap can help lessen allergic reactions. Contact your local pest control professionals to deal with cockroach infestations in the safest, most effective manner.
