Bedbugs are small insects that are normally brown in color but can be red after feeding. They live off the blood of humans and animals. Bedbugs do not fly but they can move quickly. Their flat bodies make it possible for them to fit into tiny spaces, about the width of a credit card.
Bedbugs can travel from one hiding place to another via luggage, clothing, used beds and couches. Their favorite hiding places are in mattresses, boxsprings, bed frames, and headboards. They like these areas so they can sneak out at night and bite sleeping humans. Because of this many companies are now producing bedbug proof mattress, boxspring, and pillow protectors to keep them from infesting where you sleep. Initially their bites from feeding are not painful but they turn into itchy welts much like a flea bite.
While they do not create nests like other insects bedbugs like to live in groups. Their breeding habits allow them to infest a location quickly. They can reach full maturity in as little as a month and produce more than three generations per year. Their breeding habits are how they spread to other rooms and apartments so quickly.
