But singing is usually the farthest thing from one's mind when these hardy pests become invaders. Cockroaches are the most important insect pests in Nebraska households and public places. These insects are oval, flat-bodied, dark colored, with chewing mouth parts, three pairs of legs and usually two pairs of wings. The newly emerged nymphs are identical to their parents except for their smaller size and lack of wings. The nymphs grow into adults by periodically shedding their skins, and may appear white for a few hours until their new skin darkens.
Cockroaches can be present in almost any place inhabited by humans.
They move quickly and are especially active at night. Characteristically, most roaches hide in cracks and crevices or between surfaces that provide darkness and cover. Inside buildings, roaches move freely between rooms or adjoining apartments using wall spaces, plumbing and other utility installations. They can be carried into structures in food and beverage boxes, grocery sacks, animal food and other household goods. Cockroaches can eat almost anything, but they are especially partial to starchy foods and meat products.
