More of a nuisance than a health hazard, bedbugs are showing up in hotels, college dorms, and hospitals. Bedbug bites can cause distress, a few people have allergic reactions, and scratching can lead to secondary infection, but bedbugs are not known to transmit infectious diseases to humans. Bedbugs are small, flat, wingless insects with six legs that, like mosquitoes, feed on blood from animals or people. They range in color from almost white to brown, but they turn rusty red after feeding. Bedbugs get their name because they like to hide in bedding and mattresses.
