Cockroaches

American Cockroach

slider7American cockroach adults are 1 and 1/2 inches long (38mm), making them the largest of the house-infesting cockroaches. With reddish brown, fully developed wings, the American cockroaches have a yellowish margin on the thorax or body region behind the head. When disturbed, they may run rapidly and adults may fly. Immature cockroaches resemble adults except that they are wingless.

Young roaches are wingless and nearly black with a single light stripe running down the middle of the back, and the adults are about 5/8 inch long. Egg capsules are light tan and usually yield about 36 baby cockroaches!

 

 

 

Oriental Cockroach

Oriental-Cockroach-300x197The Oriental cockroach is dark reddish brown in color, so dark that it is sometimes referred to as the “Black Beetle” in Europe and some parts of the United States. When disturbed, it may run rapidly and adults may fly. Females are wingless, and males have wings. Female Oriental cockroaches can be distinguished from large nymphs by the wing stubs which have definite venation.
