Brown Dog Tick

Adults are flat, about 1/8″ long and uniformly red-brown with tiny pits scattered over the back. Unlike the male, the female enlarges after feeding to about 1/2″ long and 1/4″ wide. The enlarged portion of the body becomes gray-blue to olive in color. Found most often in the ears, between the toes and on the backs of dogs. After feeding they retire to baseboards, molding, around window cord pulleys and protected openings.The most common roach in United States homes. Breeds throughout the year. Favors humid atmosphere and an average temperature 70°.
