Bed bugs remain a problematic pest across the United States, beyond just bed bug bites. In fact, one out of five Americans has had a bed bug infestation in their home or knows someone who has encountered bed bugs. Reflecting the increasing problem with bed bugs, a survey of pest management professionals found that prior to 2000 only 25 percent had encountered bed bug infestations, but in 2013 an amazing 99.6 percent of U.S. based professional pest management companies encountered bed bug infestations. Bed bugs are found in places beyond homes and hotels, such as hospitals, schools, doctors' offices, public transportation, college dorms, day cares, offices and any other places where humans live or gather.
My boyfriend is staying with a man who rents a room out in his house. The last tenants had bed bugs and the living room couch and everything is infested and theyve been gone for a month. The bugs were dormant until a week or two ago. The man has sprayed the house with something that is supposed to kill bed bugs yet my boyfriend is continuously being bitten. We counted around 100 bites. They are swollen and the itching is making him crazy. He is unable to sleep at night. We are trying to convince the man to just throw the couch out. Since he has no carpet we believe the couch is their main breeding ground and the sprays DID NOT WORK.
Avoidance is the best means of preventing bedbug infestation.8 While traveling, sleeping quarters and bedding should be closely inspected for signs of bedbugs. Suitcases should be placed on metal racks away from walls and furniture. Frequent travelers might consider obtaining a portable heating unit for luggage and clothing (e.g., Packtite) as an additional precaution. Items at yard sales and secondhand stores should also be carefully examined before purchase.8 All potentially infested items should be sorted and sealed in plastic bags and removed only when ready to be disinfested (see Table 36 for instructions regarding effective care of infested items). Wearing long-sleeved nightclothes can minimize exposed skin, and although insect repellants have not been shown to be reliably effective, oil of lemon eucalyptus or diethyltoluamide (DEET) might help deter bites.44,45
Bed bugs are annoying insects that hide in soft, warm places like beds, couches, and clothing. These bugs feed on their hosts at night, leaving small bite marks that, though rarely dangerous, should be treated right away to prevent unwanted symptoms and potential allergic reactions. To prevent more bites in the future, you’ll need to get rid of your bed bug infestation completely.
Specks of blood on bedding, mattresses, or upholstered furniture such as couches and headboards: Look carefully at your blankets, sheets, and mattress pads and then check the mattress and box spring. Are there specks of blood anywhere, especially near the seams? If so, there could be a bed bug infestation. You should also check for specks of blood on all upholstered furniture, including couches and headboards.
Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus. These insects feed exclusively on blood and may survive a year without eating. Adult Cimex are light brown to reddish-brown, flat, oval, and have no hind wings. The front wings are vestigial and reduced to pad-like structures. Adults grow to 4–5 mm (0.16–0.20 in) long and 1.5–3 mm (0.059–0.118 in) wide.
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
