Doctors often misdiagnose those afflicted because it is nearly impossible to tell, if you are experiencing an allergic reaction, what bit you. Often healthcare providers and individuals that have been bitten by a member of the Hemiptera order mistake bites for those of a mosquito. The only way to discern, with complete surety, what your bites are from, is to get a sample of what has bitten you.
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.
Discourage bed bug infestation by keeping clutter picked up, washing bedding and upholstery routinely and not buying used furniture. When you’re traveling, lower your risk of bringing bed bugs back home by opening your suitcase on a hotel desk or luggage rack instead of on the bed; keeping your belongings in your suitcase, not unpacked in dresser drawers; sealing dirty laundry in plastic bags that can be taken straight to the laundry room at home; and inspecting your luggage for bed bug activity before you bring it into your bedroom.
In order to get rid of this pest, you need to understand how it works. Getting rid of bed bugs can be a tricky task because they are expert hitchhikers. The best thing you can do is to entrust the task with an experienced pest control professional. However, if you are planning to do it yourself, I've provided you great tips and information about bed bugs to help you in your battle. That way, you can use your knowledge to eliminate them and keep them away.
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 bites themselves don't usually pose any major health risk since bedbugs are not known to spread diseases, but an allergic reaction to the bites may require medical attention, CDC officials say. There have also been some strange cases linked to bedbug infestations. Researchers reported in the Canadian Medical Association Journal in 2009 that they treated a 60-year-old man for anemia caused by blood loss from bedbug bites. Another study published in 1991 in the Journal of the Egyptian Society of Parasitology found that people with asthma might be more susceptible to allergic reactions from bedbug bites.
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.
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.
You can make a natural bed bug bite treatment by putting 1 cup distilled water in a spray bottle and adding 10-15 drops tea tree oil. Shake well and spray on areas of skin that have clusters of bed bug bites. Or, you could spray the remedy on a cotton pad and apply to the itchy bumps on your skin. You can also dilutes tea tree oil with a carrier oil, such as coconut oil or sweet almond oil (a few drops of tea tree per one tablespoon of carrier oil).
Application entails treating all areas where the bugs are found or tend to hide or crawl. This takes considerable effort and follow-ups are usually needed. Companies typically treat seams, folds and crevices of bed components, chairs and sofas, but usually will not spray the entire sleeping surface or seating area. They also do not spray bed sheets, blankets or clothing, which instead should be hot washed or heated in a dryer.
Insect bites, including those from the bedbug, have been proposed as a factor contributing to the formation of a cutaneous reaction termed papular urticaria. Patients with papular urticaria have been shown to demonstrate immunoglobulin (Ig) G antibodies to bedbug (C lectularius) antigens.  Thus, IgG against C lectularius, Cimex pipiens, and Pulex irritans in patients with papular urticaria may contribute the pathogenesis of this condition.
While most of the bed bugs were wiped out by the chemicals, three groups continued to thrive after being treated with chlorfenapyr, and five groups were still kicking after being treated with bifenthrin. That means that while some bed bugs will respond to these chemicals, others won't—and it's likely that more and more bugs will become resistant over time.
Research has shown that some bed bugs are resistant to the pyrethroid pesticides that have been most commonly used in recent years by pest management professionals. Likewise, pyrethroids such as deltamethrin and permethrin have been among the active ingredients most commonly available in pesticides at retail stores. The ongoing use of pyrethroids has undoubtedly contributed to the resistance we see today in some bed bug populations.
Prior to World War II, bed bug infestations were common. Since the development of synthetic organic insecticides such as DDT and chlordane almost 70 years ago, bed bug infestations in buildings have declined significantly - almost disappeared. In fact, in the United States, bed bug infestations have been exceedingly rare - almost non-existent - until a few years ago.
Select and use insecticides safely. There are no magic sprays that kill bed bugs very well. Most commercial insecticides will kill bed bugs if applied carefully and directly to the insects and their hiding places. An exception is “Bug bombs”, or aerosol foggers. Foggers are mostly ineffective in controlling bed bugs. Because bed bugs hide in crevices and voids where aerosols do not penetrate, they are able to avoid contact with these insecticides. Their use is not recommended. Some of the products you may find helpful include:
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.
DIY bed bug sprays are mostly ineffective in dealing with a large bed bug infestation. This is because a do-it-yourself method lacks proper knowledge on pest behavior to fully control the infestation. For example, bed bugs are real flat and tiny; they hide very well at unexpected places which you may not know. A pest control professional is able to identify key hotspots to treat effectively.
Some pest control firms also employ commercial steamers or spot-freezing equipment to treat areas where bed bugs are found or suspected. Used correctly, they kill bugs and eggs on contact. Neither method, however, affords residual protection against bed bugs which may have been missed. Steaming and spot-freezing equipment also have limited ability to penetrate fabric, wood, and other materials where bed bugs often reside.
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.
The exact causes of this resurgence remain unclear; it is variously ascribed to greater foreign travel, increased immigration from the developing world to the developed world, more frequent exchange of second-hand furnishings among homes, a greater focus on control of other pests, resulting in neglect of bed bug countermeasures, and increasing resistance to pesticides. Declines in household cockroach populations that have resulted from the use of insecticides effective against this major bed bug predator have aided the bed bugs' resurgence, as have bans on DDT and other potent pesticides.[medical citation needed]
