Bed Bugs in Illinois and Indiana

Bed bugs are small, brownish, flattened insects that feed solely on the blood of animals. Found throughout Illinois and Indiana, bed bugs are nocturnal and mainly active at night. During the daytime, bed bugs prefer to hide close to where people sleep. Humans serve as their primary host, however, bed bugs also feed on mammals and birds. These insects are secretive and remain well hidden in cracks and crevices located in places where they are not likely to be disturbed. Bites from bed bugs are essentially painless, so they are rarely detected at the time of feeding activity.

Bed Bug Habitat

Bed bugs do not construct nests like ants or bees and prefer to live in groups in areas where they can hide. Since people are their primary hosts, bed bugs initially hide in mattresses, box springs, bed frames, and headboards. These blood-sucking pests are efficient hitchhikers and are usually transported into dwellings on luggage, clothing, beds, furniture, and other items. Once bed bugs are introduced, they can crawl from room to room and from bedding to drapes or furniture.

Bed Bug Behaviors, Threats or Dangers

Although they do not spread disease and are not considered dangerous, the bites from bed bugs can cause allergic reactions. The first sign of a bed bug infestation is typically bites on the skin or the appearance of small brownish dots on the bed. Bed bugs can survive both low and high temperatures, are known to hide in small spaces, and they can live almost anywhere humans live. Eliminating bed bugs can be complex and difficult, and also requires the use of high heat or chemicals. If an infestation is suspected, it is recommended to consult a professional bed bug exterminator.
