Some patients develop blisters filled with blood or bloody fluid, especially on the arms and legs. These blood blisters are extremely rare and can burst, causing bleeding or oozing of the bloody fluid. Healthcare providers are not sure if the cause of these blisters is related to the bug or the human but have found groups of patients that were all bitten by bugs on the same train exhibiting this sign.
You can develop a skin infection if you scratch the bites. Rarely, a more severe allergic reaction to the bites could produce larger welts, blisters, or anaphylaxis. Bedbugs may also trigger asthma attacks and getting too many repeated bites could lead to anemia. Anxiety, insomnia, and sleep disturbances are common due to the stress of discovering bedbugs.
First, remove all affected areas such as bed linens, clothing, sheets and pillowcases and wash them in borax. For non-washable surfaces, as in drawers or cabinets, dust talcum powder on the affected area. Vacuum the area thoroughly and purchase an enzyme cleaner to clean all possible surfaces. If there are open spots or crevices in the wall, dust them with talcum powder and caulk them shut. This cleaning process should be repeated as often as possible to rid your home of the infestation.
If you suspect an infestation, experts recommend finding a professional exterminator who has experience dealing with bedbugs. Sprayed insecticides are commonly used to treat infestations, and exterminators may also use nonchemical methods, such as devices to heat a room above 122 degrees Fahrenheit (50 degrees Celsius), a lethal temperature for bedbugs, according to the Mayo Clinic. Freezing infested items for a few days at temperatures below 0 F (-18 C) may also put bedbugs to permanent rest, according to the University of Minnesota. But you may have to throw out heavily infested mattresses and other items of furniture.
Bites on dogs and cats will look much like bites on people, and the pet owner may actually suspect a mosquito or flea bit the pet. As with people, bed bugs do not stay on pets, but return to a protected harborage site after feeding. In addition to bites, the presence of the bug’s feces, cast skins and the animal’s irritation at night are also indicators of bed bugs biting pets. Therefore, one of the best things to do is inspect the pet’s bedding and frequently groom the animal while being vigilant for the telltale signs of bed bug presence.
