American Cockroach

The American Cockroach, Periplaneta americana, is the largest of the common peridomestic cockroaches measuring about 4cm in length. 

This is the the second most common type of cockroach in the world after the German cockroach.

The American cockroach inhabits sewers, but can easily move up to buildings, especially commercial and big city residential high rises. The public health risks associated with its presence stem from the eating habits of the insect and its migrant lifestyle.

This pest is omnivorous and will eat anything from sweets, fish, animal hides and paper to decaying matter and dead insects. At least 22 species of pathogenic human bacteria, viruses, fungi and worms are known to be carried by cockroaches. Their excrement and regurgitation also soils garments and surfaces that they pass.

Biology
  • The American cockroach has three life stages: the egg, nymphal instars and the adult. The life cycle from egg to adult averages about 600 days and the adult life span may be another 400 days. The nymphs emerge from the egg case after about six to eight weeks and mature in about six to twelve months. Adults can live up to one year and an adult female will produce an average of 150 young in her lifetime.
