Blattodea: Blattidae, Periplaneta Americana. 

Due to the large size and slow development of American cockroaches, large infestations of these insects are not common within houses. However, during certain times of the year, these cockroaches may move inside a house from outside sources. For example, in winter these cockroaches may move indoors, seeking warmer temperatures and food. Cockroaches may enter houses via sewer connections, under doors, around utility pipes, air ducts, or other openings in the foundation. Adult cockroaches can live up to one year, during which females produce an average of 150 young.
