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.

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.
