Treatment for bedbug bites is typically supportive. Local antiseptic lotions or antibiotic creams can be applied for secondary infections, whereas corticosteroid creams and oral antihistamines can be used for allergic reactions. Bedbugs can be eliminated through the use of permethrin insecticides, baited traps, special bedbug-free beds, and bed nets. Homemade methods, such as wrapping duct tape around bed legs as shown, may be effective, but bedbugs have been known to climb other objects and then fall down onto a bed.

It was stated in 2012 that no truly effective insecticides were available. Insecticides that have historically been found effective include pyrethroids, dichlorvos, and malathion. Resistance to pesticides has increased significantly over time, and harm to health from their use is of concern. 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. Boric acid, occasionally applied as a safe indoor insecticide, is not effective against bed bugs because they do not groom.
First up is the most commonly recommended tool by far: rubbing alcohol diluted in water. This is suggested because alcohol can kill bed bugs on contact, and evaporates shortly after, so it’s considered safe for use pretty much anywhere in a home. A recurring theme in these recommendations are household items that are considered to be safer for people than mainstream chemicals.
Avoiding bed bugs is most challenging in hotels, apartment buildings, and other places where there are many people, high turnover and ongoing opportunities for introduction of the pests. Periodic, preventive inspection by tenants, housekeeping/maintenance staff, or pest control firms is the best way to detect infestations in their initial stages when they are easiest to control. Visual inspections can be supplemented by using various monitoring devices to capture and reveal bed bugs that may have been overlooked by occupants.
A definitive diagnosis of health effects due to bed bugs requires a search for and finding of the insect in the sleeping environment as symptoms are not sufficiently specific. Bed bugs classically form a line of bites colloquially referred to as "breakfast, lunch, and dinner" and rarely feed in the armpit or behind the knee which may help differentiate it from other biting insects. If the number in a house is large a pungent sweet odor may be described. There are specially trained dogs that can detect this smell.
You’ll likely only see them in their hiding spots or crawling across the floor since, unlike other insects, bedbugs cannot fly or jump. Durham says to check along the edges of your mattress. You may see the exoskeletons that bedbugs have shed as they matured, or you may notice a musty smell, both of which indicate there could be bedbugs in the area. It can also be helpful to check your bed with a flashlight during the middle of the night (since these crawlers tend to be more active at night.)

Visit your doctor. You can also see a doctor for diagnosis if you do not find signs of bedbugs in your bed and cannot identify the source of the bites or rash. However, there is a very good chance that your physician will not be able to firmly diagnose that you have been bitten by a bedbug because the symptoms look so similar to those that result from other insect bites and skin conditions. Nevertheless, you may feel comforted by going to see your doctor, who can confirm for you that bedbugs pose little physical threat to humans.
The first sign of a bed bug problem is obvious: the bed. After bed bugs feed on humans, they'll leave behind blood stains resembling small rust spots. These will usually be found near the corners and edges of the bed. Bed bugs also shed their skin, or molt, several times as they mature, so you may find their oval brown exoskeletons during your search.
Scrub infested surfaces with a stiff brush to dislodge eggs. Vacuum the room extensively. Use a vacuum hose attachment to thoroughly vacuum cracks and crevices on furniture and along baseboards on the walls. Vacuum along baseboards, furniture, bed stands, rails, headboards, foot boards, bed seams, tufts, buttons, edges of the bedding, as well as the edges of the carpets (particularly along the tack strips). A good vacuum cleaning job may remove particles from cracks and crevices to encourage greater insecticide penetration. Bed bugs cling tightly to surfaces, so it is best to vacuum by scraping the end of the vacuum attachment over the infested areas to pull out the bed bugs. Caution: It is not good to use a bristle attachment, because you may transfer bed bugs to other areas since they cling to the brush. Dispose of vacuum cleaner bags after you are finished in an outdoor trashcan.
My husband works for a garbage company (this is how we think the invasion started) and at the moment they are localized to our bedroom and our bathroom. However, the first place we found them was in our headboard & footboard. It is wood with an intricate carving. We checked the mattress and box spring and didn’t find a thing. But they LOVE that wood.
Bed bugs can survive more than a year without feeding, but most adults and nymphs probably do not live more than six months without a meal. This ability lets them wait for transient hosts that periodically inhabit camp cabins, apartments and temporary housing. It also helps them survive transportation. Today, bed bugs “hitchhike” more easily than ever, via public transportation and luggage, and in secondhand furniture, mattresses, bedding and clothing. In multi-unit buildings, bed bug infestations that are not adequately attended to often spread between units with or without human help, making eradication much more difficult and costly.
If at all possible, pull up the carpet where it meets the wall and puff powder around the whole perimeter of the room. Inside outlet boxes is a great place to use powders because sprays and electricity don’t mix. Bellow dusters work great for spreading residual insecticide powder. An old makeup brush is a good tool to spread the dust around on hard surfaces. Bed bug powders are available the same places you’ll find the spray pesticides.
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.
It often seems that bed bugs arise from nowhere. The bugs are efficient hitchhikers and are usually transported into dwellings on luggage, clothing, beds, furniture, and other items. This is a particular risk for hotels and apartments, where turnover of occupants is constant. Bed bugs are small and agile, escaping detection after crawling into suitcases, backpacks and belongings. Acquiring secondhand beds, couches and furniture is another way that the bugs are transported into buildings. Bed bugs also can be carried in on one’s clothing, shoes or wheelchair. Once bed bugs are introduced, they can crawl from room to room or floor to floor. They can also be transported throughout buildings on people and their belongings.
Consider using insecticides. Residual insecticides (usually pyrethroids) are applied as spot treatments to cracks and crevices where bed bugs are hiding. Increased penetration of the insecticide into cracks and crevices can be achieved if accumulated dirt and debris are first removed using a vacuum cleaner. Many readily available aerosol pesticide sprays will cause bed bugs to scatter making eradication more difficult. Dust formulations may be used to treat wall voids and attics.
After the bugs developed resistance against many of the most powerful pesticides, such as DDT, exterminators had been increasingly relying on two chemicals—chlorfenapyr and bifenthrin. But until now, no one had looked at whether bed bugs were developing defenses against these chemicals too, says Ameya D. Gondhalekar, one of the study authors and a research assistant professor at the Center for Urban and Industrial Pest Management at the Department of Entomology at Purdue University.
Abrupt temperature change is best when attempting to kill bed bugs, so the bugs do not have time to adjust to the new temperature. Because it can take many hours for heat or cold to penetrate objects, the process of killing bed bugs is complicated by the density and depth of the items to be heated or frozen. It may take 15 days at 32 F to kill bed bug adults and 30 days to kill bed bug eggs that are unprotected, and much longer to kill those that are hidden inside items. Temperatures below freezing will kill quicker, but less is known about killing bed bugs with cold compared with using heat against them.
They also have the ability to travel beyond the bedroom, so all adjoining rooms should be checked for infestation. Any area that offers a layer of protection, e.g. dark, isolated areas, should be checked. They do leave excrement droppings behind, so even if they are not seen, you can often see where they have been. The best method to find them is to check only at night, and with a red light.
Can you catch some bed bugs with traps? Yup. There are many products that can catch bed bugs. One trap that is quite effective is a trap that is put under the legs of a bed to kill bed bugs as they climb up to feed. If a mattress and box spring have been protected, this method can add another layer of protection. The problem is, bed bugs don't need you to be sleeping in order to feed on you. If you take these measures, an infestation could grow in your home and begin to plague you while you're watching television, working on your computer, or even relaxing on your porch.
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.
After bedbugs find a food source, they bite down with their mouths and inject anticoagulant and anesthetic compounds into the skin. Depending on the species, these parasites feed on the host blood via 1 of 2 mechanisms. Vessel feeders directly insert their mouthparts into superficial capillaries, whereas pool feeders damage the superficial tissue and feed on the accumulated blood. As bedbugs feed, their color may change as they swell with the host blood, as shown in this picture of a larval bedbug feeding on a volunteer host.

Inspection for bed bug infestations must be very thorough. Your primary tool is a flashlight. Since bed bugs are cryptic insects and spend most of their time hiding, you will need a flashlight to find them. You must move and/or disassemble some items while searching including beds, dressers, carpets and rugs. While you inspect, be alert for a bed bug smell which has been described as an obnoxious sweetness or fresh, red raspberries. You should also look for accumulations of cast nymphal skins and for stains of blood spots on sheets and linens. A common location for bed bug infestations is a box spring. The framework is often made of wood and contains cracks can crevices suitable for harborage. Other common areas include wall voids, behind switch plates, interior corners of bedside tables, under the edges of wall to wall carpeting, couches and stuffed chairs.
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.
Bedbugs bite and suck blood from humans. Bedbugs are most active at night and bite any exposed areas of skin while an individual is sleeping. The face, neck, hands, and arms are common sites for bedbug bites. The bite itself is painless and is not noticed. Small, flat, or raised bumps on the skin are the most common sign; redness, swelling, and itching commonly occur. If scratched, the bite areas can become infected. A peculiarity of bedbug bites is the tendency to find several bites lined up in a row. Infectious-disease specialists refer to this series of bites as the "breakfast, lunch, and dinner" sign, signifying the sequential feeding that occurs from site to site. In some people, the bites can take several days to develop. The signs may become apparent up to 14 days after the bite has occurred.
Both of these types of Hemiptera are sensitive to extreme temperatures. It may be necessary to rid the infestation by exposing the area to extreme heat or cold; they are most comfortable in temperatures around eighty degrees Fahrenheit. Raising the temperature to ninety-seven to ninety-nine degrees may kill off a significant portion of the population.
Because bed bugs have become so prevalent in the past few years, many fear they’ll be their next victim. They became so anxious and paranoid of the possible bed bug presence. If you eliminate the pests though, you could have a certain sense of peace knowing that you would not be bothered or bitten them. However, you wouldn’t be able to sleep well for long if you would not kill bed bugs right and continuously do the bed bug preventive steps.
Bed bugs could be hiding in all sorts of tight spaces in your room, like wood cracks, inside books and furniture, and along the baseboards and the edges of the carpet. In this step, we’re going to clean, vacuum, and steam those areas that bed bugs are likely to be. This will cut down on the bed bug population while making it harder for survivors to hide.
