Vector Information

Bed bugs leave clear evidence of an infestation. Bed bugs are small (the size of an apple seed), parasitic insects that are reddish-brown in color and feed on the blood of humans and animals. Bed bugs are found around the world. Infestations typically occur near the areas where people sleep and are often found within eight feet of the host. The presence of bed bugs is not determined by the cleanliness of the living conditions they are found. During the day, bed bugs hide in crevices of walls, mattresses, or furniture. Bed bugs do not transmit disease, but their bites can lead to itching and an increased risk of a secondary skin infection. In general, humans may not even notice a bed bug bite, but in individuals with an allergy to bed bugs, the allergic reaction can result in enlarged bite marks, painful swellings at the bite site, or anaphylaxis. Infestations can be identified by finding the exoskeletons after molting, identifying bed bug in the fold of mattresses and sheets, identifying rust-colored blood spots on sheets due to bed bug fecal excrement, and finding bite marks on a person. Bite marks may develop 1 to 14 days post bite, and in some cases, may not develop at all. Bed bugs are normally transported from one location to another as people travel.

*Disease transmission varies locally. This map depicts where vectors can be found geographically and provides information about diseases these vectors might carry. Vectors might be present in a state or locality, however, and not be carriers of any particular disease. In addition, identified vectors may have a presence in a state, but may not be found throughout that state.
