Description:
American
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.
American
cockroaches generally live in moist areas, but can survive in
dry areas if they have access to water. They prefer warm temperatures
around 84 degrees Fahrenheit and do not tolerate cold temperatures.
In residential areas, these cockroaches live in basements, around
pipes and sewers, and may move outdoors into yards during warm
weather. These cockroaches are common in basements, crawl spaces,
cracks and crevices of porches, foundations, and walkways adjacent
to buildings. Many times, the American cockroach can be found
under decks, under mulching materials, inside hollow block construction,
or in any cool and damp area. Because of their fondness for sewers,
large populations of American cockroaches will be seen in many
cities after heavy rains or flooding. They may feed on a wide
variety of plant and animal material.
American
Cockroach Life Cycle :
Females
produce egg cases and carry them protruding from the tip of the
abdomen for about two days. Egg cases are then generally placed
on a surface in a hidden location. The female may glue the egg
case to the side of a structure or interior wall of a basement.
These egg cases may sometimes be found lying loosed in mulched
flower beds and compost piles. Egg cases are 3/8 inch long, brown,
and purse shaped. Immature cockroaches emerge from egg cases in
6 to 8 weeks. The nymphs require 6 to 12 months to mature. Adult
cockroaches can live up to one year, during which females produce
an average of 150 young.
