Often, bedbug bites are clustered along lines usually following arms and legs. Theories range from the idea that bedbugs are feeding along blood vessels to the idea that bedbugs remain with their bodies touching the bedding while they feed, and the bugs are left to feed only along lines where the skin is touching the bedding in just the right manner.

Traditional methods of repelling and/or killing bed bugs include the use of plants, fungi, and insects (or their extracts), such as black pepper;[54] black cohosh (Actaea racemosa); Pseudarthria hookeri; Laggera alata (Chinese yángmáo cǎo | 羊毛草);[15] Eucalyptus saligna oil;[55][56] henna (Lawsonia inermis or camphire);[57] "infused oil of Melolontha vulgaris" (presumably cockchafer); fly agaric (Amanita muscaria); tobacco; "heated oil of Terebinthina" (i.e. true turpentine); wild mint (Mentha arvensis); narrow-leaved pepperwort (Lepidium ruderale); Myrica spp. (e.g. bayberry); Robert geranium (Geranium robertianum); bugbane (Cimicifuga spp.); "herb and seeds of Cannabis"; "opulus" berries (possibly maple or European cranberrybush); masked hunter bugs (Reduvius personatus), "and many others".[58]
The bites usually last about 7 days, even if they are treated correctly. However, if you have sensitive skin like myself, they can last a couple weeks or in my husbands case, they last only a few days. As mentioned, if you scratch the bites its going to make things worse and besides running the risk of a bacterial infection, they will also take longer to heal so keep your nails away from them!

The safest and most effective approach to getting rid of bed bugs is heat treatment, in which a trained professional heats the home's rooms one by one to a temperature of 50 degrees Celsius and sustains the heat for four hours. Heat does not penetrate well into wall voids, though, so desiccant dusts are often applied to those areas. No single technique can eliminate bed bugs—combinations of approaches are essential to getting the job done.
Bed bugs (Cimex lectularius) are small, flat, parasitic insects that only feed on the blood of humans and animals while they sleep. They are reddish-brown in color, about 1mm to 7mm in size, and can live for several months without a blood meal. Bed bugs are not known to spread diseases, but their presence can cause itching and loss of sleep. Excessive scratching can increase the chance of secondary skin infections. Bed bugs are found all over the world and the cleanliness does not determine the presence of bed bugs.
When it comes to controlling bed bugs, "do it yourself" should not be anyone's motto. Bed bugs are notoriously difficult to eradicate - 76 percent of pest professionals say they are the most difficult pest to control.  As such, people who suspect a bed bug infestation should turn to a qualified pest professional with expertise in treating these pests. The pest professional will evaluate the extent of an infestation and recommend the best course of treatment.  In fact, the Centers for Disease Control and Prevention endorses that appropriate control of a bed bug infestation requires an experienced pest management professional and recommends that victims be advised against attempting to control measures themselves.

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.
Reactions to bed bug bites differ from person to person from none to a full-blown allergic reaction. A mild reaction may reveal flat, red bumps at the bite sites. A more severe reaction may include an irritating itch (as in my case), or swelling. Resisting the itch is incredibly difficult, but giving in to it can cause severe irritation to the skin, increasing your risk for an infection. It’s the chemicals in the bed bug’s saliva that trigger such reactions, some lasting more than two weeks.
Excessively scratching the itchy, bitten areas also may increase the chance of a secondary skin infection. Antiseptic creams or lotions can be used to ward off infection and antihistamines can be used to treat the itching. And an infestation can take a psychological toll on those affected: People whose homes have been infested with bedbugs may have trouble sleeping for fear of being bitten in the night. There are also public health, social and economic consequences; office buildings and schools often have to close if they are dealing with a bedbug infestation.
 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.

Turns out, C. lectularius is also forming a resistance to other insecticides, according to a study published online April 10, 2017, in the Journal of Economic Entomology. The researchers, from Purdue University, found that three out of 10 bedbug populations collected in the field showed much less susceptibility to chlorfenapyr, and five of the 10 populations showed reduced susceptibility to bifenthrin, according to a post on Entomology Today. The scientists defined "reduced susceptibility" as a population in which more than 25 percent of the begbugs survived after seven days of exposure to the particular insecticide.
I work @ a hotel, and just found out that one of the rooms has a bed bug problem. I work at the front desk, and never go into the rooms. But i work third shift, and sleep in the chair in the lobby. Just wanted to know what my chances were of catching them? I will be going home and looking just to make sure. But since i work here, and its un-avoidable, what are some things i can do to protect myself from taking them home?
One bed bug will usually take more than one bite. Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. It’s important to remember that the number of bites a person receives is not indicative of the number of bed bugs that feed on that person.
