During the summer months, alley ways and yards may be badly infested.They eating the list includes bark, leaves, paper, wool clothes, sugar, cheese, bread, oil, lemons, ink, soap, flesh, fish, leather, other roaches (dead or alive), or their own cast-off skins and egg-capsules.
Life Cycle: A female American cockroach produces 6 to 14 egg cases during her lifetime. She carries her egg case for a few hours or days after it is formed, then she drops or glues it in a sheltered site, often a crack or crevice, near a food source. The eggs hatch within 38 to 49 days. Early instar nymphs molt at approximately monthly intervals. Older nymphs molt at more variable intervals, usually every 1 to 6 months.
The nymph’s body weight approximately doubles between molts. There are 10 to 13 nymphal instars. Development time (egg to adult) of the American cockroach is greatly influenced by temperature; it averages about 15 months . The adult life span may be 1 year. Adult American cockroaches can continuously reproduce when conditions are favorable.
Damages: Cockroaches typically are not tolerated by humans,and the mere presence of these insects is considered a nuisance. Furthermore, American cockroaches often are responsible for significant fouling of food products and other items. American cockroaches also produce a strong, unpleasant odor, which they convey to harborage sites and food items.

Eliminating cockroach harborages involves caulking in closets and cabinets, caulking under the sink, etc., or making similar structural repairs in the kitchen, bathroom, and other areas of the house.Cockroaches typically enter homes via boxes, grocery bags, suitcases, furniture, etc. To prevent the insects from establishing a breeding population, clean up all spilled food materials, including crumbs on the floor.
