Silverfish and Firebrats


Silverfish and firebrats are flat, elongated insects, 1/2 – 3/4 inch long. Silverfish are silvery gray, while firebrats are gray with dark markings. Both have long antennae and three long bristles at the tip of the abdomen; and both are attracted to flour and starches and can damage paper, bookbindings, and fabrics. Silverfish and firebrats are found in damp locations. Firebrats require warmer temperatures than silverfish and tolerate drier conditions.
