Habits

American cockroaches often enter structures through drains and pipes. They are more active when the temperature is 70 degrees or higher, but they can survive lower temperatures with the right conditions.

Habitat

Although American cockroaches can be found in homes, they are also common in larger commercial buildings such grocery stores, food processing plants and hospitals. American roaches are also known to infest basements, yards and alleys.

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. Recent medical studies have shown that cockroach allergens cause allergies and exacerbate asthma attacks, especially in children and those living in metro-city areas. As with other species of roaches, American cockroaches can pose a threat to individuals with allergies.

American Cockroach Prevention

The best advice for American cockroach control is to practice good sanitation. To prevent American cockroaches from infesting your space, vacuum often, keep a spotless kitchen, seal all entrances around utility pipes and ventilate crawl spaces to prevent moisture buildup. If there is evidence of a cockroach infestation, contact a licensed pest professional to inspect and treat the American roach problem.
