Cockroaches have been around for over 350 million years and are found in nearly every part of the world. Cockroaches are most active at night or in the dark and prefer small spaces. Cockroaches like to live in warm, humid environments in protected cracks and crevices, under and behind appliances and in cabinets and drawers. Cockroaches like to eat starches, sweets, grease and meat products; but they also eat things like cheese, beer, leather, baked goods, starch in book bindings, glue, hair, flakes of skin, dead animals and plants. Cockroaches produce an egg case that can survive in very harsh conditions for very long periods of time until conditions improve enough for the egg to hatch. Under good conditions cockroaches multiply very rapidly.
