Extremely secretive,  bed bugs 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 and rarely detected at the time of feeding activity.

Bed bugs prefer living in groups and occupy areas where humans sleep or rest for long periods of time. Efficient hitchhikers, bed bugs are usually transported into dwellings on luggage, clothing, beds, furniture, and other items.  They conceal themselves in the seams and folds of luggage, overnight bags, bedding, furniture, and anywhere they can hide. Favoring cracks, crevices or seams, bed bugs hide in headboards, mattresses, luggage, backpacks, and upholstered furniture. Once introduced, bed bugs can crawl from room to room and from bedding to drapes or furniture.

Bed bugs are one of the most annoying pests that plague people and can be very difficult to eliminate.  Even though they do not spread disease and are not considered dangerous, 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. Bites from bed bugs may be undetected on people who have been bitten, and as a result, questionable welt-like swelling may occur. Bed bugs are resilient, so if an infestation is suspected, it is recommended to consult a professional bed bug exterminator.
