bites harmful?
Although Bedbugs bites are not normally harmful, most people become allergic to the bites just as the Bedbugs have established their colony in your home. These bites then leave itchy bumps or welts that can last 1-2 weeks without treatment. Most of the harm is psychological. Just the idea of blood sucking bugs crawling on the bed at night is frightening to most people, keeping them up at night.
