Medicated shampoos–both over-the-counter and prescription–can help get rid of them, as can combing and re-combing your hair carefully and disposing of the critters. If you do get head lice, don’t share anything that goes on your head (including hats, brushes, headphones, or hair accessories), and make sure you clean bedding and clothing that could have been infested in hot water.
The prognosis for bedbug bites is excellent. The vast majority of people who experience bedbug bites will recover without any long-term problems, and many individuals who are bitten may not exhibit any physical signs at all. However, the recent resurgence in bedbug infestations will require increasing public education and awareness, instituting effective preventive and control measures, and continuing research into the development of more effective, safe insecticides.
The life cycle stages of a bed bug are egg, nymph, and adult. The reason they are called bed bugs is that they readily infest mattresses, bed frames and box springs. Eggs are laid along the edges of or around buttons on the mattresses. Eggs can also be glued to rough surfaces. Bed bug females lay about 200 eggs, usually at the rate of three or four a day. Eggs are placed in cracks, crevices and other isolated and protected shelters. Females lay eggs after a blood meal. Eggs will hatch in one or two weeks into Nymphs. Newly hatched bugs (Nymphs) begin feeding immediately. At room temperature, and with an available food supply, the nymphal period will last 14 to 30 days. They shed their skin (Instar) five times before becoming adults. Bed bugs will mate soon after becoming mature, so the time from egg hatch to egg laying is 4 to 9 weeks, under favorable conditions. The average life span of the bed bug is 6-12 months and they feed every 10 days or so during this time. Bed bugs can survive many months without a blood meal and their reproduction is high.
It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.
Individual responses to bites vary, ranging from no visible effect (in about 20–70%), to small macular spots, to prominent wheals and bullae formations along with intense itching that may last several days. The bites often occur in a line. A central spot of bleeding may also occur due to the release of anticoagulants in the bug's saliva.
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.
