Description

General name for flat, oval-shaped brown insects of the family Blattidae. They are common household pests and can grow to 9 cm long. Cockroaches are nocturnal and sensitive to light. They have highly sensitive antennae that enable them to detect tiny amounts of food and moisture. Their ability to sense air movements allows them to flee from danger. Both the nymphs and adults feed on almost anything, such as starchy, sugary, and proteinaceous foods. They will eat cloth that is sized with starch or glue. Common desiccating powders such as boric acid, Dri-die and sulfur are used along with pesticides to exterminate cockroaches. Pyrethrin powder is also commonly used but it is most effective as an attractant and knock-down agent, not as as insecticide.

See also American cockroach, brown banded cockroach, German cockroach and oriental cockroach.
