Bedbugs feed by biting people when they’re asleep. Some people develop localized swelling or an itchy welt around these bites. Others don’t react to them at all. Bedbugs feed at night and hide during the day. Their favorite hiding spots are where people sleep. Being flat, they can easily slip into tiny crevices in bed frames and headboards. They also like to tuck into areas around mattresses and boxsprings. They don’t nest, but they will congregate in habitual hiding places. Since not all bites or bite like reactions are caused by bedbugs, it’s important to confirm a bedbug infestation before mounting an attack. Signs of one include
Dark spots and stains on mattresses, caused by dried bedbug excrement. Eggs and eggshells, and/or molted skins from maturing nymphs. Rusty or reddish blood spots on mattresses and/or bed sheets. A buggy or sweetish odor. This is typically associated with heavy infestation. The bugs themselves.
Bedbugs are extremely efficient at catching a ride on luggage and clothing. Travel to a foreign country, and you just might bring back a few with you. Other bedbug transports include old mattresses, box springs, and other bedroom furniture. Once in a home, bedbugs easily spread from room to room. Since they only feed on blood, even the most spotless home can harbor them. As such, an infestation typically requires calling a pest-control specialist.
IPM Controls
Nonchemical controls for bedbugs include:
Regularly vacuuming mattresses, carpets, walls, and other surfaces. Pay particular attention to the edges, seams, and tufts on mattresses and box springs, and the edges of wall-to-wall carpets, which are prime bedbug hangouts. Steam cleaning carpets, upholstery and drapes. This will kill any bugs and eggs that vacuuming misses. Throwing away affected mattresses. If this isn’t an option, cover mattresses with zippered cases designed for preventing dust mites. Thinking twice about buying secondhand bedroom furniture. If you do, examine pieces carefully before bringing them home. If traveling internationally, examine beds and headboards for signs of bugs. Keep luggage off the floor.
Bedbugs can’t climb slippery things. Coating bedlegs with petroleum jelly can keep them from climbing up. Placing bed legs in bowls of soapy water or putting the legs inside glass jars or metal cans can also keep bedbugs from bugging you.
Chemical Controls
Residual insecticides containing pyrethroids or natural pyrethrins are commonly used on bedbugs. Dusts containing diatomaceous earth are useful in hard-to-reach places. These products adhere to the hair on pest bodies and causes death by dehydration. Application is best done by a pest-control specialist.
