Itchy swollen bites may be the first sign of a bed bug problem. However, these itchy bites can take as long as 14 days to develop in some people, so it's important to look for other clues if you are concerned about an infestation. Bed bugs typically infest mattresses, box springs, bed frames, and couches. You may be able to find them hiding within the cracks and crevices of beds, furniture, floors, and walls. Bed bugs often leave evidence of small dark stains (fecal droppings) and rusty red spots (bloodstains) on bedding sheets, mattresses, and other areas they hide in or travel along. Heavy bed bug infestations can cause a sweet, musty smell.
Occasionally, you might find other bugs which resemble the common bed bug including the bat bug and swallow bug. Both of these species superficially resemble the common bed bug. However, their primary hosts are bats and birds and there are small but diagnostic morphological differences. Problem infestations with these bugs may occur in attics or unused chimneys. Typically, when one host is gone these bugs seek an alternative host blood meal. This is when humans are bitten. It is important to differentiate between the common bed bug and other bugs that feed on bats and birds because control efforts can be targeted at the wrong sites and infestations can continue.

Insecticides are an effective way to eradicate bed bugs, but not the only way. If you or someone in your house is highly sensitive to chemicals, or you’re just not crazy about the idea of spraying chemicals where you sleep, kill the little blood suckers with heat. Temperatures above 120 degrees F kill all stages of bed bugs. Steamers can be used to treat all the same areas where you would have sprayed contact killers. Steamers like the one shown at (top) cost about $150 and are good for many other projects like removing wallpaper, cleaning tile, removing labels, cleaning engine parts and removing wrinkles from fabric.
Dusts have been used to ward off insects from grain storage for centuries, including plant ash, lime, dolomite, certain types of soil, and diatomaceous earth or Kieselguhr.[60] Of these, diatomaceous earth in particular has seen a revival as a nontoxic (when in amorphous form) residual pesticide for bed bug abatement. While diatomaceous earth performed poorly, silica gel may be effective.[61][62]
Bedbugs are highly resistant to many sprays. There are, however, certain sprays that may be able to kill bedbugs. Check with a professional exterminator about advice using sprays to try and remove the bedbugs yourself. Dead bedbugs usually won't move, may be arched back, or red in color. Ultimately, you may be better off replacing your mattress and bedding and fumigating your home to kill the bedbugs.
Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] These insects feed exclusively on blood and may survive a year without eating.[3] 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.

Bed bugs were mentioned in ancient Greece as early as 400 BC, and were later mentioned by Aristotle. Pliny's Natural History, first published circa AD 77 in Rome, claimed bed bugs had medicinal value in treating ailments such as snake bites and ear infections. (Belief in the medicinal use of bed bugs persisted until at least the 18th century, when Guettard recommended their use in the treatment of hysteria.[51])

As for traps, these capture methods may not be full-proof for all bedbug species. Researchers have found that while both the common and tropical bedbug species have hairy feet, C. hemipterushas denser foot hairs, making this tropical insect an expert climber on slick surfaces. In the study, detailed on March 15, 2017, in the Journal of Economic Entomology, the researchers found that adult tropical bedbugs were much better at escaping traditional pitfall traps, which held onto most of the common bedbugs in the study.
Probably chiggers -- they are very small, red mites that usually cannot be seen with the naked eye. They are about as small as the period at the end of this sentence. To stop the itching, use OraJel (usually sold for teething babies), which contains benzocaine (an anesthetic). Also, rub in hydrocortisone cream. To prevent chigger bites, wear long pants and stuff the cuffs into your socks.
What can I do about head lice? Head lice are tiny, parasitic insects that live on the scalp, usually on young children. They are not dangerous but are highly contagious and can be difficult to remove. Treatment involves OTC or prescription medication, but resistance to these treatments is growing.

Reality: Bedbug control can only be maintained through a treatment strategy that includes a variety of techniques plus careful attention to monitoring. Proper use of pesticides may be part of the strategy, but will not by itself eliminate bedbugs. In addition, bedbug populations in different areas of the country have developed resistance to the ways many pesticides work to kill pests. If you're dealing with a resistant population, some products and application methods may not work. It is a good idea to consult a qualified pest management professional if you have bedbugs in your home.
But the bites will look different from person to person, and some people won’t develop any reaction whatsoever. “The same bedbug could bite two different people and one could have no reaction at all and the other can have an extreme reaction with a swollen arm or itchy rash,” says Eric Braun, a board-certified entomologist and business manager for the national pest control company Rentokil Steritech, who is based in Redding, Pennsylvania. Some people end up developing a rash that looks like eczema. (5) 

If you need to treat items that can’t be laundered or steamed, you can use a portable bed bug heater, like a ZappBug Oven or a ThermalStrike Ranger. These heaters can safely treat household items like books, papers, CDs, and dry clean only clothing. Not only are bed bug heaters an effective part of a bed bug treatment process, but they’re one of the most popular prevention tools on the market. When you come home from a trip, just put your suitcase in the heater, zip it shut, and turn it on. In just a few hours, any bed bugs or eggs hiding in your belongings will be dead.
Apply residual Bed Bug Insecticide Spray. After every crack, crevice, switch plate, electrical switch, baseboard, box springs, mattress, etc, has been treated and everything is put back, it is time for the residual treatment. Using a hand held sprayer such as the Chapin Sure Spray apply Optimate, Cy-Kick, Suspend SC or Demand along the baseboards in the bedroom and closet, under and around the bed, behind the headboard, inside bed stands etc.
The bed bug (Cimex lectularius) has been a parasite of humans throughout written history. Its adaptation to humans is so complete that its bite is not noticed until well after the bug leaves its victim, if it is noticed at all. Attracted by the warmth of our bodies and the carbon dioxide we exhale, bed bugs emerge usually at night from hiding places, seeking human blood. While pathogens have been found in bed bugs, the bed bug apparently does not transmit diseases to humans.

Bed bug bites are caused primarily by two species of the insect Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] Their size ranges between 1 and 7 mm.[7] They spread by crawling between nearby locations or by being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high-density areas.[8][2] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark, hidden locations like mattress seams or cracks in the wall.[2]
Discard affected items. In some cases, infested mattresses and box springs will need to be discarded. Since bed bugs can disperse throughout a building, it also may be necessary to inspect adjoining rooms and apartments. Pay it forward: chop up and/or damage the items you discard so nobody will be tempted to take them home and spread the problem further.[17]
To use sprays effectively to eliminate all traces of bed bugs, you need to know the signs of a bed bug infestation. The first sign that you may have bedbugs are some itchy bite marks on your skin when you wake up in the morning. Dr. Carol DerSarkissian on WebMD says that the bites from bed bugs cause red itchy bumps on the skin.3 You can learn about their other signs and symptoms in my articles on what do bed bug bites look like.
