American Cockroach

At an inch and a half long, the American cockroach is the largest species of cockroach known to infest homes and buildings. These pests have large reddish-brown wings and light markings on their thorax.

Sometimes referred to as a water bug, the American cockroach tends to live in damp, humid areas, but does not choose to enter water and does not actually live in water. Their attraction to sewers is believed to be the reason for the mistaken reference.

They are frequently found in places where food is prepared, but the American cockroach is more likely to be seen outdoors than other species. It also is more likely to be seen during the daytime, while other species are generally nocturnal.

Their populations can grow quickly, as they eat virtually anything and they are excellent scavengers. They have shown a special attraction to alcoholic beverages, especially beer, and they can be aggressive in their behavior.

The American cockroach prefers areas that are warm and damp for hiding and laying eggs. Their egg capsules are typically deposited in warm protected areas.

A female mates only once to produce several egg capsules, each containing about 13 eggs. Nymphs do not reach maturity for about 600 days, and an adult lives for up to 15 months.
