Bedbugs may enter your home undetected through luggage, clothing, used beds and couches, and other items. Their flattened bodies make it possible for them to fit into tiny spaces, about the width of a credit card. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy access to people to bite in the night. 

Bedbugs are most often found in hotels, hostels, shelters, and apartment complexes where lots of people come and go. Because bedbugs hide in small crevices, they can hitch a ride into your home on luggage, pets, furniture, clothing, boxes, and other objects. Bedbugs are found worldwide, but are most common in developing countries. Once rare in North America, they may be on the rise due, in part, to increases in international travel.

However, low-level infestations are also much more challenging to find and correctly identify. Other insects, such as carpet beetles, can be easily mistaken for bed bugs. If you misidentify a bed bug infestation, it gives the bugs more time to spread to other areas of the house or hitchhike a ride to someone else's house to start a new infestation. Learn about identifying bed bugs.
Bed bugs are active mainly at night. During the daytime, they prefer to hide close to where people sleep. Their flattened bodies enable them to fit into tiny crevices--especially those associated with mattresses, box springs, bed frames and headboards. Bed bugs do not have nests like ants or bees, but do tend to congregate in habitual hiding places. Characteristically, these areas are marked by dark spotting and staining, which is the dried excrement of the bugs. Also present will be hatched and un-hatched eggs, the tannish shed skins of maturing nymphs, and the bugs themselves. Another possible sign are rusty or reddish smears on bed sheets or mattresses from crushed engorged bed bugs. Although it’s often stated that bed bugs have a telltale “buggy” odor, the smell is seldom evident except in extreme infestations and should not be relied upon for detection.
Bedbug bites can lead to anxiety, sleeplessness and even secondary infections, but there have been no reported cases of bedbugs transmitting disease to humans. They do, however, harbor human pathogens: At least 27 viruses, bacteria, protozoa and more have been found in bedbugs, although these microbes do not reproduce or multiply within the insects. Canadian researchers announced (pdf) in the June issue of Emerging Infectious Diseases that bedbugs isolated from three individuals in a Vancouver hospital carried methicillin-resistant Staphylococcus aureus, aka MRSA. Still, there have been no reported cases that the bugs actually transmit human disease.

After repeated bedbug bites, a person’s skin may become sensitized to the saliva of the bedbug, and subsequent bites may cause an allergic response, resulting in itching and inflammation. It is important not to scratch the red, itchy spots, as they can become infected. If you think you may have been bitten by bedbugs, talk to your doctor. They may prescribe antibiotic or antiseptic creams to prevent infection and corticosteroids and antihistamines to treat allergic reactions.[25]
Bed bugs are one of the most difficult pest problems to eradicate quickly. By far, the best solution for bed bugs is to hire a pest control company with experience successfully controlling bed bugs. Unfortunately, this can be expensive and beyond the means of many people. If you feel you cannot afford to hire a professional, and want to attempt do-it-yourself bed bug control, there are some things you can do. With diligence and patience and some hard work you have a fighting chance of getting rid of bed bugs in your home.
Insecticides might also have their work cut out for them: Entomologists have known that the common bedbug has built up resistance to some typical insecticides such as those containing certain pyrethroid chemicals like deltamethrin, according to Entomology Today. Deltamethrin apparently paralyzes an insect's nervous system, according to Cornell University.
Desiccant dusts.  Two low toxicity dusts with good effectiveness include silica aerogel and diatomaceous earth (DE).  Both of these dusts are low risk to humans, and work by desiccating, or drying out, bed bugs that come in contact with it. Silica aerogel is, in some studies, superior for this purpose.  It is sold under various trade names including Tri-Die™ and CimeXa™.  Diatomaceous earth can also be effective.  Look for DE for insect control–it is not the same product as diatomaceous earth used in swimming pool filters, which is dangerous to breath. Some pest control companies now use desiccant dusts extensively in bed bug control. These relatively inexpensive dust can be purchased online or in garden centers or hardware stores. Look for products labeled for indoor use and lightly dust all accessible crack, crevices and voids.  A paint brush is useful for applying these dusts to seams and crevices in sofas and mattresses, along baseboards and inside drawers and dresssers.

Vacuum your house. This will remove bugs and eggs from mattresses, carpet, walls and other surfaces. Pay particular attention to seams, tufts and edges of mattresses and box springs, and the perimeter edge of wall-to-wall carpets. Afterward, dispose of the vacuum contents in a sealed trash bag. Steam cleaning of carpets is also helpful for killing bugs and eggs that vacuuming may have missed.[14]
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:
Next, apply a bed bug powder into confined areas where it won’t be stirred up into the air. Places like the edges of carpeting, inside deep cracks and wall voids, and inside electrical outlets and light switches (accessed by removing the faceplate with a screwdriver) are good candidates for powders, as sprays can’t reach into these areas quite as well. We recommend using a professional powder applicator, which offers better control when applying the powder.
Some people have no reaction whatsoever to bed bugs. In addition to not having much of an effect on the elderly, some are just not allergic. Since the irritation and welting appears as the result of an allergic reaction, it is possible to not even know that you were bitten at all. It is entirely possible for several people to live in the same house, and have one person not be affected.

Vigilant travelers may also want to elevate suitcases off the floor on a stand, tabletop or other hard surface rather than storing them on the floor or another bed. Hyper-vigilant travelers may further opt to keep belongings in sealed plastic pouches and their suitcase in a zippered tote — however each traveler must decide how cautious they wish to be. 
Skin reactions from bed bug bites vary from person to person. Bites may go unnoticed or may be mistaken for flea or mosquito bites or other skin conditions. The most common skin reaction to bed bug bites are itchy red bite marks that appear clustered or in a straight line, often along the edge of clothing or where sheets were pulled up to a person's skin. Small swollen red bumps are also common. In rare cases, people may develop large, often itchy, red welts. A single bed bug bite is similar to a flea bite, except that a red area does not occur in the center. Flea bites tend to be found around the ankles while bed bugs tend to bite any exposed area of the body while a person is sleeping, such as the face, neck, arms, hands, or legs.
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.

Well, among others, you would want to purchase Bed Bug Bully. As stated in FIFRA 25 (b), it is a minimum-risk pesticide. That’s because it is made with organic-based products. More than that, pest-control companies already proved that they truly work withtheir continuous use of it. And with its new licensing agreement, you could also now enjoy its effectiveness, safety and affordability.
Oil-based products have been so frequently touted as natural bed bug killers that they’ve even attracted government intervention. The Federal Trade Commission has charged multiple companies with deceptive advertising for overhyping their cedar oil-based products’ ability to treat an infestation. By claiming that their products can stop and prevent bed bug infestations, these marketers opened the door to government lawsuits for misleading their customers.
We recommend spraying Steri-Fab in areas where live bed bugs are visible. Steri-Fab combines a synthetic pyrethroid insecticide and isopropyl alcohol to kill bed bugs fast on contact. Steri-Fab also acts as a sanitizer. Steri-Fab does not leave any residual, meaning it can be applied virtually anywhere. Simply shake well, then apply to desired treatment areas. Insect mortality is imminent, generally within 10 minutes of spraying.

Once the mattress and box spring are dry, encase them in sealed bed bug encasements. Encasements are crucial, as they prevent bed bugs from entering or escaping the mattress and box spring, cutting off key hiding places. Remember to leave the encasements on for at least 18 months to ensure that any bed bugs already inside have starved to death. Once the encasements have been applied, you can put your mattress and box springs back on your treated bed frame, and put your laundered bedding back on your bed.
It should also be noted that pest management professionals are subject to state regulation, licensing and regulation, while bed bug dog teams are typically unregulated. In Illinois, for example, bed bug detection dogs are regarded as inspection tools, not devices that facilitate the application of pesticides. A few private organizations certify dogs and their handlers as bed bug detectors, holding them to certain standards before awarding certification. But at present, these organizations, like dogs and handlers, are not subject to regulations that govern those who apply pesticides to control bed bugs. Nevertheless, the National Pest Management Association (NPMA) recommends that bed bug detection teams be independently certified and adhere to the minimum standards found in the NPMA’s Best Management Practices for Bed Bugs (see RESOURCES for more info). 
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. 

Bedbug bites themselves are typically painless. However, the subsequent allergic reaction that may develop can cause intense pruritus. While feeding, bedbugs may inject one of several pharmacologically active substances, including hyaluronidase, proteases, and kinins. These compounds may induce different skin reactions, such as erythema, wheals, vesicles, or hemorrhagic nodules. Repeated bites may sensitize individuals, leading to more pronounced cutaneous manifestations or systemic hypersensitivity reactions. The local trauma from bedbug bites can lead to secondary bacterial infection, causing ecthyma, cellulitis, or lymphangitis. There is some evidence that bedbugs may also be a vector for hepatitis B and Chagas disease. Histologic findings from bite-site biopsy specimens typically show eosinophilic infiltrates, which are indicative of the allergic nature of the reaction. The image shown is papular urticaria, which may develop from bedbug bites.
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]

While your laundry cycle is running, use a vacuum cleaner to remove any bed bugs, shells, fecal droppings, or eggs that might be along the seams of your mattress, pillows, box spring, and along the cracks and crevices in the bed frame, headboard, and footboard. Follow up the vacuuming with a high pressure steamer to penetrate deep inside mattresses, box springs, bed frames, headboards, and footboards to kill bed bugs and eggs on contact.
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. 

A hair dryer might seem like a safer way to kill bed bugs with heat. Unfortunately, their maximum temperature is rarely more than 150 degrees. That heat level can kill bed bugs, but only if you maintain the heat over them for several minutes. So unless you want to follow each bug you see around with a hair dryer until they eventually die, you’d probably be better off just hitting them with the thing.
Bring in only what is needed, and avoid sitting or placing coats and other items on beds, floors and sofas where the bugs commonly reside. Essential items can be placed on a tabletop or other hard surface, preferably away from bedrooms and sleeping areas. Better to sit on a hard (non-upholstered) chair than on sofas and recliners. Also try to avoid leaning or brushing against beds and upholstered furniture. If such items are carried out of infested dwellings (e.g., by sanitation workers or firefighters), it’s best to wrap them in plastic or at least not hold them against your body during transport. Emergency Medical (EMS) personnel may need to take additional precautions, such as removing a patient’s bed bug-infested shoes or clothing, or installing plastic sheeting before transporting them in the emergency vehicle.
