"By every metric that we use, it's getting worse and worse," says Coby Schal, an entomologist at North Carolina State University in Raleigh. Health authorities and pest control operators are regularly flooded with calls, and the epidemic may not have yet peaked. And because bedbugs are indoor pests, there are no high or low seasons throughout the year, he adds, only continual bombardment. "It's just the beginning of the problem in the U.S.," Schal says.
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.
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. 

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:
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.
RID Home Lice Control Spray has always contained the same active ingredient, Permethrin, to kill lice and their eggs on bedding, furniture, car interiors and other non-washable items. Permethrin is also effective at killing bedbugs and dust mites. That is why RID Home Lice Control Spray has been renamed and is now called RID Home Lice, Bedbug & Dust Mite Spray.
Probably chiggers -- they are very small, red mites that usually cannot be seen with the naked eye. They are about as small as the period at the end of this sentence. To stop the itching, use OraJel (usually sold for teething babies), which contains benzocaine (an anesthetic). Also, rub in hydrocortisone cream. To prevent chigger bites, wear long pants and stuff the cuffs into your socks.
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.
According to the Texas A&M University, there are no “magic” insecticide sprays for bed bugs. However, both natural and chemical sprays have a measure of effectiveness against bed bugs. One of the benefits of chemical sprays is that they are stronger and will kill off bed bugs quicker. However, the drawback is that many populations of bedbugs have become resistant to pyrethrins and pyrethroids – the 2 main chemicals in many chemical bed bug sprays. Therefore, they may not be effective in reducing many bed bug populations.5
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”.
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.    
Pesticides should always be used with caution, and especially when used indoors.  Never use a pesticide for bed bugs that does not bear clear directions stating that it can be used indoors.  Never spray yourself, children or pets with a pesticide.  And follow the label safety directions carefully.  Pesticide labels contain directionsfor use that are not merely suggestions.  Failure to follow directions exactly is illegal and can result in poor control and possible harm to yourself and family.  For more information, see the EPA Consumer Alert on pesticides and bed bugs.

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.
Bed bugs are an increasing cause for litigation.[69] Courts have, in some cases, exacted large punitive damage judgments on some hotels.[70][71][72] Many of New York City's Upper East Side home owners have been afflicted, but they tend to be silent publicly in order not to ruin their property values and be seen as suffering a blight typically associated with the lower classes.[73]

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.”
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.
Checking beds for bed bugs was a common practice long ago, especially while traveling. Travelers today should consider doing the same, preferably before unpacking. This would entail examining the bed sheets and seams of the mattress and perhaps box spring for signs of bed bugs, especially along the head (pillow end) of the bed. Experts also remove and check behind headboards since this is a frequent hiding place for bed bugs in hotels. Headboards are heavy and cumbersome, however, and untrained persons should not attempt removal themselves.
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.
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.
Should I worry about a tick bite? Ticks are parasites that feed on blood, and although their bites are harmless they can still transmit diseases, such as Lyme disease or Rocky Mountain spotted fever. Learn what ticks are and how to recognize the signs and symptoms of a bite. This MNT Knowledge Center article also explains how to prevent tick bites. Read now
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.
Bed bugs are annoying insects that hide in soft, warm places like beds, couches, and clothing. These bugs feed on their hosts at night, leaving small bite marks that, though rarely dangerous, should be treated right away to prevent unwanted symptoms and potential allergic reactions. To prevent more bites in the future, you’ll need to get rid of your bed bug infestation completely.

Some pest control firms utilize specialized heating equipment to de-infest furnishings, rooms, and entire dwellings. The procedure involves heating up the infested item or area to temperatures lethal to bed bugs. Portable heaters and fans are used to gradually heat the air to about 120 - 130°F while monitoring with strategically placed sensors. By carefully controlling the temperature, bugs and eggs are killed wherever they may be without damaging household items. 
You can check bedding, mattresses, furniture, and crevices in walls for bed bug infestation. Do your inspection just before dawn, which is when they are the most active. The bugs will be larger and slower after feeding. Bedbugs will quickly flee from light, so live bugs are best located in the folds and seams of mattresses and sheets. Bedbugs are about the size of an apple seed, about 1/4 inch long. They change from light brown to purple-red after feeding. You may also see their eggs, which are about the same size as the adults. The eggs will often be in seams, cracks, or crevices.
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
These nocturnal creatures can hide in beds, floors, furniture, wood, and paper trash during the day. We humans usually become their dinner during the night, with peak biting activity just before dawn.They can obtain their meal in as little as three minutes, after which they are engorged and drop off the host, then crawl into a hiding place to digest their meal. Bedbugs can live for 10 months, and can go weeks without feeding.
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.
Ticks are known transmitters of disease to humans and animals. Tick-borne diseases include Lyme disease, Rocky Mountain spotted fever, Q fever, tularemia, babesiosis, and Southern tick-associated rash illness. Infected ticks spread disease once they've bitten a host, allowing the pathogens in their saliva and mouth get into the host's skin and blood. Tick bites are typically painless, but the site of the bite may later itch, burn, turn red, and feel painful. Individuals allergic to tick bites may develop a rash, swelling, shortness of breath, numbness, or paralysis. Tick bite treatment involves cleaning and applying antibiotic cream.

Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
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.
While alcohol can kill bed bugs on contact, it’s not going to kill nearly enough of bed bugs to be considered effective. In lab studies, even 99 percent concentrations of alcohol only killed between 40% to 60% of the adults that were sprayed. On top of that, alcohol has no long-lasting residual effect, and doesn’t affect bed bug eggs. 60% sounds good, but a contact killer should be able to kill a lot closer to 100% of the bed bugs you see. Otherwise, a shoe or a blowtorch would be the more reliable tool for the job. (Editor’s note: please don’t use a blowtorch.)
Hiring a pro to wipe out bed bugs isn’t cheap. Expect to pay about $200 per room to kill bed bugs, and you’ll likely need a few chemical treatments in order to eradicate bed bugs. Professional heat treatments will cost even more. And even if you hire a pro, you’ll still have to do lots of work yourself (moving furniture, washing all clothes, etc.). So consider declaring a DIY war on bed bugs. If you’re willing to spend $100 to $200 and do things right, your chances of success are excellent.
Flea bites are caused by the parasitic insect, the flea. The most common species of flea in the US is the cat flea, Ctenocephalides felis. Signs and symptoms of flea bites in humans include itching, hives, a rash with bumps, red spots with a "halo," and swelling around the bite. Treatment for flea bites includes over-the-counter medicine and natural and home remedies to relieve and soothe itching and inflammation. The redness of a flea bite can last from a few hours to a several days.

Bed bug infestations have resurged since the 1980s[43] for reasons that are not clear, but contributing factors may be complacency, increased resistance, bans on pesticides, and increased international travel.[44] The U.S. National Pest Management Association reported a 71% increase in bed bug calls between 2000 and 2005.[45] The number of reported incidents in New York City alone rose from 500 in 2004 to 10,000 in 2009.[46] In 2013, Chicago was listed as the number 1 city in the United States with the worst bed bug infestation.[47] As a result, the Chicago City Council passed a bed bug control ordinance to limit their spread. Additionally, bed bugs are reaching places in which they never established before, such as southern South America.[48][49]

Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
