Bed bugs are small, oval and brownish insects that live on the blood of humans while asleep. Immature bedbugs which are called nymphs, shed their skins five times before reaching maturity and require a meal of blood before each shedding. After feeding, a bed bug's body swells and becomes a reddish color.
Over a lifetime, a female bed bug will lay hundreds of eggs; each of which is about the size of a speck of dust. Under favorable conditions, bed bugs can develop completely in as little as a month and they will produce three or more generations each year. Although bed bugs are a nuisance, they do not transmit diseases.
Bedbugs may enter your home undetected through luggage, clothing, used beds and furniture. Their flattened bodies make it possible for them to fit into very small spaces. Bed bugs do not have nests like ants. They generally live in groups that are found in secure hiding places. Their typical hiding places include mattresses, box springs, bed frames, and headboards; where they have easy access to people to feed on during the night.
Over time, bed bugs may scatter throughout the bedroom, finding refuge within furniture, curtains, clothing and any crevice or protected location. They may also spread to nearby rooms or apartments.
