A bedbug will pierce the skin of its host with its mouth part. It first injects saliva that is a mixture of an anesthetic, so that the host feels nothing, and an anticoagulant so that the blood flows out freely. It then sucks out blood until it is full. The bites are not noticeable until after the skin reaction has occurred. According to the Centers for Disease Control and Prevention (CDC), it can take up to 14 days for bites to appear.
Human infestation with bedbugs, lice, and mites are common causes of dermatologic symptoms. Although these organisms thrive in conditions of overcrowding and decreased sanitation, Americans of all socioeconomic backgrounds may be at risk for infestation. Clinicians must maintain high suspicion in the appropriate set of clinical circumstances to identify and treat infestations, as they can cause substantial dermatologic and psychological discomfort for patients.

Bed bugs are small, flat insects that feed on our blood, typically at night, while we are sleeping. Adult bed bugs are about 1/4 of an inch long, have flat, rusty-red-colored oval bodies, and look like an apple seed. They feed for about 3-10 minutes and their bodies swell and become bright red. During the bed bug life cycle, a female can lay 200-400 eggs depending on food supply and temperature. Bed bugs don't fly, but can quickly walk across floors, walls, and other surfaces.
Thus, although these insects usually cause mild cutaneous reactions, more severe responses, including anaphylaxis, may occur. [9] Bullae may be noted. Skin responses at bite sites may evolve from immediate, pruritic, edematous macules into bullae within 24 hours. Histopathologically, an urticarial-like reaction can develop into a leukocytoclastic vasculitis, sometimes with a destructive, necrotizing, eosinophil-rich vasculitis with prominent infiltration of CD68+ histiocytes and collagen necrobiosis.
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.
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.
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.
With practice and a flashlight, nonprofessionals can become proficient in finding and destroying bed bugs. The process is made easier by reducing clutter, especially in bedrooms and sleeping areas. Bugs that are spotted can be removed with a vacuum (see previous discussion), or killed with over-the-counter insecticides labeled for such use. Most bed bug sprays intended for householders have little remaining effect after the spray has dried. Therefore it’s important to initially contact as many of the insects as possible with the spray droplets. Insecticide labels should be read carefully as some bed bug products should not be used on mattresses and seating areas. Some insecticides applied as powders or dusts (e.g., diatomaceous earth) will kill bed bugs although boric acid powder will not. However powders can be messy and difficult to apply, especially by nonprofessionals. Total release foggers (otherwise known as ‘bug bombs’) are ineffective against bed bugs and potentially dangerous when used incorrectly (see University of Kentucky entomology fact sheet Limitations of Home Insect Foggers).

The most frequent bed bug encountered in the United States is Cimes lectularius, the common bed bug. However, one other bed bug species occasionally found in the southern United States, is Cimex hemiperus, the tropical bed bug. Both of these species are oval, flat and reddish brown. They range from one-fourth inch to five-eighths inch in length. Nymphs and adults have piercing-sucking mouthparts and are incapable of flight. However, small stubby wing remnants can be observed on the adults.
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.
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.
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]
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.
Susceptibility to arthropod bites depends on many external factors, such as occupation, conditions of employment, cohabitation with a variety of domestic animals, housing, climate, and clothing. An arthropod is usually attracted to its host by body heat, carbon dioxide in exhaled air, vibration, human sweat, and/or odor. The Cimex (bedbug) genus attacks both mammals and birds. C hemipterus (the tropical bedbug) bites mostly humans and is found in warm climates, whereas C lectularius (the common bedbug) also attacks bats and domestic animals, such as chickens.
Kept replacing the sticky traps just in case but never caught anything other than the occasional spider. Always cycled the sheets and such using the car+sun. They were still getting to us. Bed bugs cannot fly or jump. They had to be in the bed frame. I check it over and notice rusty spotting, which is apparently bed bug fecal matter. Luckily ours was from IKEA so it was easy to take apart – and sure enough – there they were. The way my bed works is a metal frame with holes, rubber end caps fit into those holes, and wooden slats run across the frame in the end caps. So every few days I’d mix up a 50/50 mix of bleach and water in a bucket and soak the wooden slats and end caps for ten minutes. The bed bugs were gone a couple of weeks and came back. I started soaking the things longer and scraping them with a disposable spoon, which was hard to do on the end caps. It warped the wood a little but nothing too bad. After a couple of weeks or so, I stopped finding bed bugs in the frame. I was worried they were in the metal too, but I completely stopped getting bites. I think the added time and scraping got rid of eggs. Not a lot can survive a 30 minute bleach bath.
Bed bugs are highly vulnerable to heat; exposing them to a certain amount of direct heat will kill them instantly, while lower temperatures can kill them in a matter of minutes. This is why many forms of heat treatments are recommended. Some methods, such as steamers and portable heaters, have been proven effective through professional use and are quickly becoming standard issue in holistic treatment arsenals.
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”. 

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.

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.

I was at a motel for a week, and had no problems with bed bugs. I then left to go to a shelter, because I had no more money to pay for a motel. The second day I went job searching all day, and started itching really bad on the back of my neck. At first I thought it was from the heat, and from me sweating. I then looked at my neck and noticed red swelling bites on my neck, and I scratched it to make the itch go away. I then noticed as the day progressed that it was spreading fast up the back of my neck. Now I’m getting worried, what is this, and why is it itching and spreading so fat. I asked the shelter workers what they thought it was and they said, I don’t know, but you can take anti-itching cream. I took the cream and put it on my neck, the itching went away, but the bites still were there. The next day I wake up and I have another bite on my upper right arm, and a bite on my right thumb. That night I talked to a resident staying there, and she said you have bed bug bites. I was so disgusted and scared. She then told me that three other people had the same problem I did, with the red bumps on their neck too, and they had left because of it. I want your advice on if I should persue legal action. Thank YoU
The decline of bed bug populations in the 20th century is often credited to potent pesticides that had not previously been widely available.[44] Other contributing factors that are less frequently mentioned in news reports are increased public awareness and slum clearance programs that combined pesticide use with steam disinfection, relocation of slum dwellers to new housing, and in some cases also follow-up inspections for several months after relocated tenants moved into their new housing.[66]
Never treat any bedding, mattress, etc. with anything other than the treatments listed: borax, enzyme cleaner, Comet, sodium borate. Other pesticides and exterminating fluids can be harmful to humans. Even so, bedding and mattresses treated with chemicals such as borax or Comet should be left outside to dry naturally in the sun, then wrapped in plastic before next use, so as not to irritate the skin.
This question is answered by the condition of the mattress and the size of infestation. If there are holes or tears in the gauze fabric or fabric of the mattress, bed bugs and eggs may be inside, as well as outside. There are restrictions on how beds can be treated with insecticides. We carry both Mattress Safe Bed Bug Encasements and ActiveGuard Mattress Liners.

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.
Check to see if you can identify the rust-colored fecal stains, egg cases, and shed skins (exuviae) in crevices and cracks on or near beds. A sweet, musty odor is sometimes present. You should also look at other areas such as under wallpaper, behind picture frames, in couches and other furniture, in bedsprings and under mattresses, and even in articles of clothing. While fecal stains and skin casts suggest that bedbugs have been present, these do not confirm that the infestation is still active. Observing the bedbugs themselves is definitive confirmation that an area is infested. You may require professional assistance from a pest-control company in determining whether your home has a bed bug problem.
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.

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.   


To know it's bedbugs, it's important to find the bugs themselves. Look at bedsheets and mattresses for little spots of blood, rusty-looking stains (crushed bugs), or black dots (bugs' poop). You might see live bugs around the seams or tags of mattresses and box springs, or in cracks of bed frames and other furniture. They can even hide in books, carpet edges, and electrical outlets.
Individual responses to bites vary, ranging from no visible effect (in about 20–70%),[5][3] to small macular spots, to prominent wheals and bullae formations along with intense itching that may last several days.[5] The bites often occur in a line. A central spot of bleeding may also occur due to the release of anticoagulants in the bug's saliva.[4]
Bed bugs like to travel and are good hitchhikers. They will hide in suitcases, boxes and shoes to be near a food supply. They are elusive, nocturnal creatures. They can hide behind baseboards and in cracks, crevices, and folded areas of beds, bedding and adjacent furniture, especially mattresses and box springs. Bed bugs can also hide in electrical switchplates, picture frames, wallpaper and nearly anywhere inside a home, car, bus, or other shelter. Bed bugs usually come out at night for a blood meal. However, they are opportunistic insects and can take a blood meal during the day, especially in heavily-infested areas. Bed bugs usually require 5-10 minutes to engorge with blood. After feeding, they move to secluded places and hide for 5-10 days. During this time in the bed bug life cycle, they do not feed but instead digest their meal, mate, and lay eggs.
Are there pesticides that kill bed bugs? Yup. There sure are. Pest control companies often use pesticides to exterminate these bugs as part of a heat treatment, and also by themselves. But chemicals have some drawbacks that pest professionals are aware of. These products can drive bed bugs into walls, like an improperly applied heat treatment, and they can be ineffectual if bed bugs are deep inside furniture. There are also safety considerations that need to be considered when applying any pesticide.
Bed bugs will also succumb to cold temperatures below 32°F, but the freezing temperatures must be maintained for a longer period (e.g., one to two weeks). Consequently, heating tends to be a better option throughout much of the country. Efforts to rid entire dwellings of bed bugs by raising or lowering the thermostat will be unsuccessful, although pest control firms are able to achieve lethal temperatures with supplemental heaters (see the subsequent section entitled "Heat Treatments" for more details). 
Alcohol will kill bed bugs but not their eggs and will need to be used often to control infestation. It is not an effective way to get rid of bed bugs permanently. If you want to use this bed bug treatment you need to mix nine parts 91 percent isopropyl (rubbing) alcohol with one part water. Place the solution in a chemical sprayer to cover large areas. Use a spray bottle for small areas and to get into crevices. Spray all areas including head/foot boards, hard surfaces, base boards, door jams and any other bed bug hiding spots.

It's possible that your son is just the only one showing a reaction to them - or the bedbugs are in his room somewhere. Thoroughly examine the bedding, mattress, under the bed, and the room in general. Usually it's best to call an exterminator to completely get rid of bed bugs. As for where they came from in the first place, there's usually numerous ways for bugs to get into a house or apartment - cracks, open doors/windows, unknowingly bringing into the home something with bedbugs, etc.

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.)
Use precautions in your own home. Keep the plastic covering that comes on your mattress when purchased new. Purchase special bedbug covers for you mattress and box spring. Make sure that they are quality ones with heavy duty zippers and constructed with special fabric that doesn't rip easily. Don't buy the cheap versions which are not thick enough to prevent the bedbugs from sticking their feeding tubes into the skin through the cover.[19]

Steaming is a great option in rooms and areas where the use of pesticides must be limited due to health or other concerns. When using the steamer, take your time and slowly move the steamer across the item you are treating for the best possible treatment. We still strongly recommend you follow-up with an insecticide labeled for bed bugs in areas where it is permissible to do so. All steaming should be done prior to covering a mattress or box spring with a protective cover and applying insecticides.
If you arrive home and discover that you have brought some unwanted guests home with you, immediately notify the hotel of your discovery. Having a possible infestation in hotels and motels can be a public relations nightmare for the owners. Politely ask them to pay for any and all costs incurred to rid your clothing and home of a possible new infestation.

CrossFire Bed Bug Concentrate has two different active ingredients for dual modes of action (both a quick kill and residual activity). Mix 3 oz of CrossFire Insecticide with one gallon of water or 0.75 oz per quart (Remember to use what you mix-within 24 hours.) Adjust the spray pattern to a mist by turning the nozzle. A low fine mist is best for most spraying, but you may need to use a stream to get into some cracks and crevices. If you can't get into the cracks and crevices use one of the aerosols described below with it's crack and crevice tips to reach into these areas.


Dust every crack and crevice. Every crack and crevice, electrical switch plate, wall switch - EVERYTHING - within 10 to 15 feet of the bed should be treated, particularly those closest to the bed. Use the "running method" of moving the application tip along the length of the crack. Look for cracks from the ground level to the ceiling as you treat each section of the room. Use Cimexa Dust or Delta Dust. If you make a mess, simply wipe it up. To much insecticide is better than too little for bed bug control.
Insecticide Application This is the most common way to get rid of bedbugs, Lazarus says. Oftentimes, the professional will use several different products to effectively treat the area, though it may take a few rounds to ensure removal. “The advantage to this method is that the residual insecticide will continue to offer protection for a period of time,” Lazarus says. “The biggest drawback is that the preparation for service is time-consuming and must be repeated prior to each service.”
