Because their bodies are flat, they can hide under the smallest spots like the border of beds, under the mattress, edges of carpets, couches, cracks in the walls and ceilings, in your pillows, under your bed sheets, behind electrical plugs and wall sockets, in your cupboards and dressers, or under furniture. In fact, bed bugs prefer any fabric materials. They can travel pretty good distances, too. Expect them to be able to be found anywhere in the room.
Bed bugs are experts at hiding. Their slim flat bodies allow them to fit into the smallest of spaces and stay there for long periods of time, even without a blood meal. Bed bugs are usually transported from place to place as people travel. The bed bugs travel in the seams and folds of luggage, overnight bags, folded clothes, bedding, furniture, and anywhere else where they can hide. Most people do not realize they are transporting stow-away bed bugs as they travel from location to location, infecting areas as they travel.
Bed bugs are very resilient. Nymphs and adults can persist months without feeding which is unusual for most insects. The ability to survive without a blood meal is longer at cooler temperatures ― potentially up to a year or longer at 55°F or less. In temperature-controlled buildings, a more typical duration is about 2 to 6 months. Consequently, it is usually impractical to leave buildings unoccupied in hopes of ‘starving out’ an infestation. When infested dwellings such as apartments are vacated, bed bugs often disperse to nearby units, or reduce their activity until the unit is reoccupied. 
Although bedbugs are generally nocturnal, they're like humans—if they're hungry, they'll get up and get something to eat. "If you go away to visit a friend for a week and you come back and sit down on the couch, even though it's daytime the bedbugs will come looking for you," Schal says. Keeping a light on, then, unfortunately does not keep these tiny vampires away.
If, after everything is thoroughly taken apart and cleaned, you still have an infestation, other measures may need to be taken. If you have an infestation of bats, you may also have a serious infestation of “bat bugs” which are very similar to the common variety. Often, the infestation is not as strong as those caused by their cousins as they are more apt to wander and relocate.
Stripping and vacuuming the mattresses and box springs, and encasing them.  Double bag your bedding and wash in hot water and dry for at least 30 minutes (discard the inner bag after putting bedding into the washer, as it could have bed bugs).  After vacuuming suspected bed bugs from the bed, take your vacuum cleaner outdoors and remove and discard the bag.  Purchase a good quality set of bed-bug-proof encasements for your mattresses and box springs. Bed bug-proof encasements are fabric sacks into which you slide your mattress or your box spring. The zippers on bed bug encasements are designed to be tight enough to prevent even the smallest life stages of the bed bugs from escaping. Also, good bed bug-proof encasements are woven to prevent bed bugs from biting you through the encasement. A good encasement will trap all bed bugs in the mattress and box spring inside, and will be smooth on the outside, providing few places for bed bugs to hide. Sears, Target, Walmart and other stores may sell bed bug-proof encasements, but these can also be purchased online. A good place to look for different brands and reviews of mattress encasements is Amazon.com (whether you buy there or at a local store). Go to http://www.amazon.com and search for “bed bug mattress protectors”.

Bed bug sprays usually act as an insecticide and repellent. The best kind of bed bug sprays should kill bed bugs on contact and need to be used repeatedly to help eliminate your bug problem. According to the Texas A&M University, bed bug sprays are best used in combination with other bug control methods like natural bed bug powders. This is because bed bugs don’t build up resistance to natural bug powders and products like diatomaceous earth which kills bed bugs as long as the powder is dry.5
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]
Apply as a coarse, low-pressure spray to harborage areas including crevices, baseboards, loose plaster, behind bed frames and headboards, beneath beds and furniture, and to bedsprings and bed frames. After removal of bed linens, apply Transport Mikron to mattress and boxsprings. Apply to tufts, edges, seams and folds (do not spray clothes or bed linens). Your may apply it to furniture, but not to areas where there is direct access to seating or arm placements. Infested bed linens should not be treated, but should be removed, placed in sealed plastic bags, and taken for laundering and drying at high temperatures.
Some firms want beds stripped and furniture moved before they arrive, while other firms prefer to inspect first and perform these tasks themselves. Clutter and belongings on floors (especially beneath beds) must be removed since they impede treatment and afford additional places for bugs to hide. Bedding and garments normally will need to be laundered and/or hot dried (120°F minimum) since they cannot be treated with insecticides. An effective and efficient alternative to laundering is to simply place bedding, clothing, toys, shoes, backpacks, etc., in a clothes dryer set at medium-to-high heat for 10 to 20 minutes. This can be done in lieu of washing and will kill all bed bug life stages. 
Low toxicity contact sprays like SteriFab™ or Bedlam® are likely to kill bed bugs only on contact. Alcohol- and soap-based sprays, are only partly effective. All of these products, once dry, are likely to provide no further control. Eggs will not be killed by alcohol-based sprays, so repeat treatments are usually needed. Be careful when using sprays containing alcohol because they may be flammable.
The scientific name for bed bugs is Cimex lectularius. They are small creatures that grow up to 5 mm in size, or about the size of an apple seed. They have a flat oval-shaped body and will become significantly larger if they have fed. According to the United States Environmental Protection Agency, bed bugs start life as a tiny egg, then grow into a nymph before becoming an adult.1
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]

We are often asked, "How do you kill bed bugs?" While we would love to give a simple answer, this is actually a loaded question. There are many ways to kill a bed bug but, if you want to kill all of the bed bugs in your home or business, it is important to pay attention to the details. Here are some ways you can kill bed bugs, and what you should know about each.

In the case of beds, a more economical option is to encase both the mattress and box spring in a protective cover like those used for allergy relief. Encasements specifically designed to help protect against bed bugs are available through retail or pest control firms. Higher quality ones tend to be more durable and comfortable to sleep on. Once the encasement is installed and zipped shut, any bugs which happen to be inside are entombed and eventually will die. Encasements also help protect newly purchased beds, and make it easier to spot and destroy any bugs residing on the outer surface during subsequent examination. Encasements will not, however, keep bed bugs from crawling onto a bed and biting a sleeping person.
It was stated in 2012 that no truly effective insecticides were available.[6] Insecticides that have historically been found effective include pyrethroids, dichlorvos, and malathion.[4] Resistance to pesticides has increased significantly over time, and harm to health from their use is of concern.[3] The carbamate insecticide propoxur is highly toxic to bed bugs, but it has potential toxicity to children exposed to it, and the US Environmental Protection Agency has been reluctant to approve it for indoor use.[33] Boric acid, occasionally applied as a safe indoor insecticide, is not effective against bed bugs[34] because they do not groom.[35]
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.
Alcohol. 90% works best. On contact … also…they go where the blood is…. you must wash everything in very hot water. Then put freshly washed and folded clothes in clean plastic bags. Store for as long as possible… spray Carpet.. baseboards..clothes bedding..mattresses.. etc.. etc.. you can buy a large sprayer at walmart for $5.00 . Saves time… do not spray alcohol on some items. It will ruin. Your leather…shoes. Luggage purses..etc..
To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.
Heat treatments of this type are advantageous because they present no pesticide hazard. However, they also provide no residual activity. That is, they do not prevent a structure from being re-infested after it is heat treated. For this reason, residual pesticides are often applied in conjunction with heat treatments. Such applications may not prevent re-infestation, but help control any bed bugs not killed by the heat. A certain percentage of heat treatments, perhaps 10 to 20 percent, fail to kill all the bed bugs present. Often this is due to residents failing to adequately prepare the premises for heating.

As mentioned earlier, applying insect repellent at bedtime will probably not deter bed bugs from biting. When working in severely infested dwellings, there may be some benefit to spraying tops and bottoms of shoes with DEET-based repellents. Those working in bed bug-infested environments may also want to hot wash or run clothing, etc. through a dryer upon returning home or to the office.     

An adult bed bug is about 1/5 inch long and 1/8 inch wide. Its reddish brown to mahogany-colored body is greatly flattened and oval shaped. After feeding, the bug's body enlarges considerably, becoming longer and much less flattened. Although the body is covered with tiny hairs, these hairs are so small that they are almost invisible to the naked eye, so the general body appearance is shiny. Bed bugs have piercing-sucking mouthparts that enable them to pierce the skin and suck blood from their hosts.
We are often asked, "How do you kill bed bugs?" While we would love to give a simple answer, this is actually a loaded question. There are many ways to kill a bed bug but, if you want to kill all of the bed bugs in your home or business, it is important to pay attention to the details. Here are some ways you can kill bed bugs, and what you should know about each.
It’s perfectly natural to want to eliminate a bed bug infestation without spending a ton of money on professional-grade products or a treatment by a pest control operator. When people discover that they have bed bugs, they often turn to do-it-yourself recommendations from discussions on the Internet. These suggestions might include household items, some of which are recommended more often than others. Let’s take a closer look at some of the most popular items and how they might be used against bed bugs:
Heat Remediation For this method, the area is heated to about 130 degrees F and maintained so the heat moves into the furniture and everything else in the room. Lazarus says there’s less preparation needed with this method (you’ll likely just need to remove things that are sensitive to heat, like medication and plants). It usually takes just one treatment to effectively kill all of the bed bugs at their various life stages. Sometimes heat remediation is used along with insecticide for an extra-thorough approach.
Bed bugs can exist singly, but tend to congregate once established. Although strictly parasitic, they spend only a tiny fraction of their lifecycles physically attached to hosts. Once a bed bug finishes feeding, it relocates to a place close to a known host, commonly in or near beds or couches in clusters of adults, juveniles, and eggs—which entomologists call harborage areas or simply harborages to which the insect returns after future feedings by following chemical trails. These places can vary greatly in format, including luggage, inside of vehicles, within furniture, among bedside clutter—even inside electrical sockets and nearby laptop computers. Bed bugs may also nest near animals that have nested within a dwelling, such as bats, birds,[22] or rodents. They are also capable of surviving on domestic cats and dogs, though humans are the preferred host of C. lectularius.[25]

Start in the corners and along edges of an open wall.  With the card, see if you can dig things out of the cracks and crevices. Work your way along the cracks and crevices. For example, if you are checking a baseboard along the floor, see if you can get the card between the baseboard and the floor, as well as the top of the baseboard and the wall. If you have a bare tile or wood floor, consider using a damp cloth or map to wipe the floor.  Don’t use too much water as floors can be slippery.  Look for anything moving after you wipe the floor. If you have carpeted areas vacuum the clean area. See Vacuuming Items to Capture Bed Bugs.  Don’t forget to check pictures and other items on this wall.
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.
Considering how time-consuming and costly it can be to eradicate bed bugs, it’s prudent to take precautions and avoid infestations in the first place. Householders should be vigilant when acquiring used furnishings, especially beds and couches. Discarded items should be avoided, and secondhand articles should be examined closely before being brought into the home. Look carefully in the folds and seams of furniture for signs of bed bugs (see the previous section entitled "Description and Habits" for more details). There is no reason to stop shopping in consignment stores, yard sales, etc., but it would be prudent to run clothing and fabric items through the washer or dryer before storing them in the home. The risk of acquiring bed bugs from items purchased in antique stores would generally be insignificant.      

Inspection requires knowledge, dedication and time. At minimum an inspection should involve a detailed examination of mattresses, box springs and bed frames, as well as likely hiding places for bed bugs within 20 feet of beds and other places where residents may sleep or rest, e.g., on couches). Clutter-free space will be needed to allow furnishings to be moved and manipulated for inspection. In general, rooms with more furnishings will take more time to inspect.
Minimize its spread. First, notify your landlord if you rent in a building to control its spread to other units. Thoroughly vacuum any infested areas, including carpets and mattresses, and then empty the vacuum bag into a plastic bag, seal it, and throw it in the trash outside. If you can’t get the bed bugs out of your furniture, discard items in a responsible manner. To avoid someone else from salvaging infested furniture or mattreses, rip, remove stuffing, or spray paint with the words “bed bugs.”
In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. "Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says. Those spots are left behind after a bedbug has been smashed.
Pay attention to when the bites occur. Consider, for example, if you notice the bites after waking up when previously you hadn't noticed them. However, this can also be difficult to determine because each person's reaction time can vary significantly. Symptoms that result from the bite can manifest at any point from a couple of hours to more than a week after the bite occurred.
