The American cockroach is the largest of the house-infesting
cockroaches.
Habits
American cockroaches are found in food processing areas and food
storage areas, as well as other types of buildings. They are active
when the temperature is 70 degrees or higher, but they can survive
lower temperatures with the right conditions.
Habitat
American cockroaches are often found in sewers and basements,
particularly around pipes and drains.
Threats
American roaches have been reported to spread at least 33 kinds
of bacteria, six kinds of parasitic worms, and at least seven other
kinds of human pathogens. They can pick up germs on the spines of
their legs and bodies as they crawl through decaying matter or
sewage and then carry these into food or onto food surfaces. Germs
that cockroaches eat from decaying matter or sewage are protected
while in their bodies and may remain infective for several weeks
longer than if they had been exposed to cleaning agents, rinse
water, or just sunlight and air. Recent medical studies have
shown that cockroach allergens cause lots of allergic reactions in
inner city children. American roaches were even shown to cause
asthma in children. These allergens build up in deposits of
droppings, secretions, cast skins, and dead bodies of roaches.
