Bedbugs are small, flat, reddish-brown insects about the size of a lentil or apple seed.
Bedbugs get their name because they like to hide in the cracks and crevices of a bedroom or sleeping area.
Before World War II, bedbugs were common throughout the United States. Bedbugs have made a come back since the early 1990s because pesticides have changed, people travel more often and used furniture is more common. Bedbugs can be found around the world -- in resort hotels, universities, cruise ships, homes and apartment complexes.
Bedbugs have even been found in Egyptian tombs dating back more than 3,000 years. Bedbugs do not care where they live. They can live in either a clean or a dirty environment. You are just as likely to find them in a world-class hotel, or anywhere where people rest or sleep.
Like mosquitoes, bedbugs feed on blood from animals or people during the night and hide during the day.
