German Cockroach.
The German cockroach is the cockroach of concern, the species that gives all other cockroaches a bad name. It occurs in structures throughout Florida, and is the species that typically plagues multi-family dwellings.
Latin Name
Blattella germanica
Appearance
The adult is 10-15 mm long, brown to dark brown in color with two distinct parallel bands running the length of the pronotum. The male body is thin and slender, its posterior abdomen is tapered, and the terminal segments of the abdomen are visible and not covered by tegmina (leathery outer wings). The female's body is stout, its posterior abdomen is rounded, and the entire abdomen is covered by tegmina.
Habitat
They are unable to survive in locations away from humans or human activity. The major factor limiting German cockroach survival appears to be cold temperatures. Studies have shown that German cockroaches were unable to colonize inactive ships during cool temperatures and could not survive in homes without central heating in northern climates. The availability of water, food and harborage also govern the ability of German cockroaches to establish populations.
