Bed Bugs are rusty and reddish in color. The unfed bed bug is flat and thin, they become rounder and redder after feeding. During the day they hide in cracks and crevices. They leave those areas to feed on blood sources mainly from humans. Feeding takes anywhere from 3 to 10 minutes and is not usually noticed by the host. Treatment is best completed by a professional. Customers must follow pre-treatment instructions and guidelines in order to have successful elimination.
