How can I treat a bedbug bite?

Bedbug bites should go away within 2 weeks. In the meantime, you can try an over-the-counter (OTC) hydrocortisone cream or lotion on the affected skin to relieve the itchiness and swelling. An OTC antihistamine pill or cream called diphenhydramine (brand name: Benadryl) may also relieve itchiness caused by bedbug bites.

Its important to avoid scratching your bites as much as possible. Scratching can damage your skin, which makes it more likely to get infected.

If an OTC cream doesnt relieve your itchiness, you may need to ask your doctor about a prescription-strength medicine to treat your symptoms.

If your bedbug bites become infected, talk to your doctor. You may have an infection if the skin around your bites becomes red and swollen, you have a fever, or your bites blister or become sores. Your doctor may prescribe an antibiotic to treat your infection.

If you have a severe allergic reaction to a bedbug bite, see your doctor right away.

If you have bedbugs in your home, wash all of your pajamas and bedding in hot water and dry them in a hot dryer, or freeze them for at least 24 hours. Vacuum all of your furniture, especially your mattress and its seams. If your mattress is infested, either replace it or cover the mattress and box springs in plastic covers. Fix any cracks in your furniture. Fill and seal any cracks or holes in the walls or floors.

If your infestation is severe, you may need to contact a pest control professional. Ask questions about what chemicals they use, and be sure to keep children and pets away during spraying.

Bedbugs | Treatment

common name: bed bug scientific name: Cimex lectularius Linnaeus (Insecta: Hemiptera: Cimicidae) Introduction - Distribution - Description - Life Cycle - Survey and Management - Selected References Introduction (Back to Top)

Sometimes referred to as red coats, chinches, or mahogany flats (USDA 1976), bed bugs, Cimex lectularius Linnaeus, are blood-feeding parasites of humans, chickens, bats and occasionally domesticated animals (Usinger 1966). Bed bugs are suspected to carry leprosy, oriental sore, Q-fever, and brucellosis (Krueger 2000) but have never been implicated in the spread of disease to humans (Dolling 1991). After the development and use of modern insecticides, such as DDT, bed bug infestations have virtually disappeared. However, since 1995, pest management professionals have noticed an increase in bed-bug-related complaints (Krueger 2000).

Human dwellings, bird nests, and bat caves are the most suitable habitats for bed bugs because they offer warmth, areas to hide, and hosts on which to feed (Dolling 1991). Bed bugs are not evenly distributed throughout the environment but are concentrated in harborages (Usinger 1966). Within human dwellings, harborages include cracks and crevices in walls and furniture, behind wallpaper and wood paneling, or under carpeting (Krueger 2000). Bed bugs are usually only active during the night but will feed during the day when hungry (Usinger 1966). Bed bugs can be transported on clothing, and in luggage, bedding and furniture (USDA 1976)/ Bed bugs lack appendages that allow them to cling to hair, fur, or feathers, so they are rarely found on hosts (Dolling 1991).

The adult bed bug is a broadly flattened, ovoid insect with greatly reduced wings (Schuh and Slater 1995). The leathery, reduced fore wings (hemelytra) are broader than they are long, with a somewhat rectangular appearance. The sides of the pronotum are covered with short, stiff hairs (Furman and Catts 1970). Before feeding, bed bugs are usually brown in color and range from 6 to 9.5 mm in length. After feeding, the body is swollen and red in color (USDA 1976).

The two bed bugs most important to man are the common bed bug, Cimex lectularius, and the tropical bed bug, Cimex hemipterus. These two species of bed bugs can be easily distinguished by looking at the prothorax, the first segment of the thorax. The prothorax of the common bed bug is more expanded laterally and the extreme margins are more flattened than that of the tropical bed bug (Ghauri 1973).

Because of their confined living spaces, copulation among male and female bed bugs is difficult. The female possesses a secondary copulatory aperture, Ribaga's organ or paragenital sinus, on the fourth abdominal sternum where spermatozoa from the male are injected. The spermatozoa then migrate to the ovaries by passing through the haemocoel, or body cavity (Dolling 1991). The female bed bug lays approximately 200 eggs during her life span at a rate of one to 12 eggs per day (Krueger 2000). The eggs are laid on rough surfaces and coated with a transparent cement to adhere them to the substrate (Usinger 1966). Within six to 17 days bed bug nymphs, almost devoid of color, emerge from the eggs. After five molts, which take approximately ten weeks, the nymphs reach maturity (USDA 1976).

Bed bugs are most active at night, so their infestations are not easily located (Snetsinger 1997). However, when bed bugs are numerous, a foul odor from oily secretions can easily be detected (USDA 1976). Other recognizable signs of a bed bug infestation include excrement left around their hiding places (Dolling 1991) and reddish brown spots on mattresses and furniture (Frishman 2000). Good sanitation is the first step to controlling the spread of bed bugs. However, upscale hotels and private homes have recently noted infestations, suggesting that good sanitation is not enough to stop a bed bug infestation (Krueger 2000).

If bed bugs are located in bedding material or mattresses, control should focus on mechanical methods, such as vacuuming, caulking and removing or sealing loose wallpaper, to minimize the use of pesticides (Frishman 2000). The effectiveness of using steam cleaners or hot water to clean mattresses is questionable. Heat is readily absorbed by the mattress and does no harm to the bed bug. For severe infestations, however, pesticides may be used. Care should be taken not to soak mattresses and upholstery with pesticides. Allow bedding and furniture to dry thoroughly before using. One study shows that over-the-counter foggers are not effective for controlling bed bugs (Jones and Bryant 2012).

Bed bug bites look very different from one person to another. Some bedbug bites are larger, some smaller, some have a red dot in the center, or a scab, others dont, some look like mosquito bites or pimples. Some bed bug bites are in groups of 2 or three (a pattern known as breakfast, lunch, and dinner), or in a line, or in a circle. Others are single bites.

Ive heard from experts that whether you get multiple bites in a pattern may have to do with whether the bed bug is disturbed while feeding (if you move, they may move and start over) and also whether your veins are easily accessed by the bed bugs (if they are, they need pierce only once).

Dermatologists and PCOs cannot identify a bed bug bite or distinguish it from something with another cause.

A dermatologist can test a skin reaction and determine its an insect bite, but cannot be certain its from bed bugs.

Many people dont even react to bed bug bites.

For this reason, you cant be sure you have bed bugs unless you find visual evidence (bed bugs, a cast skin, bed bug eggs, or fecal stains). See this gallery for pictures of bed bugs and signs of bed bugs.

However, people still do ask what bed bug bites look like, so below are some examples.

Note that we have a FAQ on remedies for itching caused by bed bug bites, and additional posts about bed bug bites, photos of bed bugs bites and bed bugs biting, and other related topics.

bed Bug Bites: Photos And Information

By Dr. Jorge Parada National Pest Management Association Sunday, April 21, 2013 Bed bugsremain a problematic pest across the United States, beyond just bed bug bites. In fact, one out of five Americans has had a bed bug infestation in their homeor knows someone who has encountered bed bugs. Reflecting the increasing problem with bed bugs,a survey of pest management professionalsfound that prior to 2000 only 25 percent had encountered bed bug infestations, but in 2013 an amazing 99.6 percent of U.S. based professional pest management companies encountered bed bug infestations. Bed bugs are found in placesbeyond homes and hotels,such as hospitals, schools, doctors offices, public transportation, college dorms, day cares, offices and any other places where humans live or gather. Bed bugs are active in summer and winter and are not considered seasonal in the same sense that mosquitoes, ticks and stinging insects are. Still, many consider bed bugs to be a greater problem in the warmer months, however it is not the bed bugs that are more active in the summer months the humans are. In warmer weather we typically travel more, often sleeping in hotels and motels, using various modes of transportation, and thereby increasing our risk of exposure to bed bugs. The bed bugs themselves are year-round pests. Becoming a victim of a bed bug infestation is certainly devastating, but the public can rest easy knowing that these pests are not known to transmit any diseases. While it is true that some pathogens have been detected in and on bed bugs including hepatitis B, and exotic organisms such as Trypanosoma cruzi (cause of Chagas Disease, rarelyfound in the United States) or Wolbachia species, unlike mosquitoes and ticks, bed bugs have not been associated with disease transmission. Bed bugs do not transmit MRSA. Although there have been reports of persons developing methicillin resistant Staphylococcus aureus (MRSA) infections, such as boils or abscesses associated with bed bug bites, it turns out the bed bugs really werent directly at fault. Rather, the cases of MRSA infections associated with bed bug bites are actually an example of scratching leading to minor skin trauma and subsequent secondary bacterial infections. In these cases, people who are carriers of MRSA scratch at the itchy bite sites and provide a port of entry for the MRSA (which was already present on their skin) to get in and under the skin and cause the secondary infection. While it can be blamed for some other bed bug symptoms like itching and red welts, the bed bug cannot be blamed for the infection. Some people experience anxiety, sleeplessness and unease as symptoms of having had bed bugs. Lets face it, bed bug infestations are understandably significant psychosocial stressors, and some people may experience sleeplessness as they worry about bugs biting them or their family members. Not surprisingly, people have been known to self-isolate, avoiding family and friends out of concern for spreading the infestation, or (if word gets out that they have bed bugs) they may be avoided by friends or others in the community, or find they have problems at work. As a result, victims of bed bug infestations may experience moderate to severe levels of stress, anxiety and depression. In severe cases, these persons should seek counseling and treatment as required. Bed bugshave flat oval bodies, six legs, are reddish-brown in color and are similar in size to a dog tick many have described the adults as resembling a flat apple seed. Adult bed bugs are approximately 1/4 inch long, while nymphs (juveniles) may be as small 1/16 of an inch. With feeding, they enlarge or engorge with blood. The adults turn from a brownish to reddish color, while the translucent nymphs may become bright red during the feeding process. Just because you cant see bed bugs, does not mean that they are not still there. Bed bugs are rarely seen in the day, out in the open or on the surface of beds or chairs. They have been described as champions of hide-and-seek. So, it is not uncommon to miss the bed bugs altogether. Bed bugs love to hide in the cracks and crevices associated with mattresses, cushions, bed frames and other structures, which is why it is very important to look for telltale symptoms of bed bugs and signs of an infestation, such as shed skins and specks of blood or feces on linens, furniture, mattresses and other areas where the bugs might be hiding. Bed bug bites can look a lot like other insect bites. Some clues that can suggest the presence of bed bugs include finding red, itchy bites upon awakening especially if the bites line up in a row on the skin. Bed bugs typically bite at night on exposed areas of skin, so the bites are most commonly found on the face, neck, hands and arms. Although some people develop a bite reaction immediately, others may take two to three days before a reaction becomes noticeable, and not all people have obvious bed bug bite symptoms. A bed bug bite can appear as a tiny puncture wound without a surrounding reaction, and can easily be missed. In fact, 30 percent of individuals living in bed bug-infested dwellings report a lack of bites or skin reactions. This appears to be more common amongst the elderly. On the other hand, other people have exuberant reactions, with large, red, raised and itchy welts. This is especially true if one becomes sensitized to bed bug bites, so that with repeated bites there is an increased risk of an exaggerated reaction to bed bug bites. In infestations with persistent, repeated exposures, bed bug bites may appear in crops. Also, since bed bug bites usually take three to six weeks to heal, as long as the infestation is still present, new bites may accumulate even as the older ones start to resolve. Thus, people may have various bite reactions in various stages of evolution at the same time. Bed bugs typically feed at night when we are sleeping. Even though these pests commonly feed for 5 minutes, the bite itself is painless and usually goes undetected at the time. In fact, bed bugs inject an anticoagulant (a blood thinner) as they feed, which makes feeding easier for the bed bug and also less detectable to you. Although you may not see the bed bugs, or feel their bites, they know when you are around. Bed bugs are attracted to warmth and carbon dioxide. So, if you are alive, warm, and breathing then you are broadcasting loudly and clearly to all nearby bed bugs that dinner is served! Bed bug bites do not typically require treatment. It is best to clean the bite site(s) with soap and water and avoid scratching so as to prevent secondary infection. Progressive swelling, warmth, tenderness and sometimes (albeit rarely) fever may be signs of secondary infection, which should be managed with antibiotics as appropriate. Much more common are complaints of itching. For how to treat bed bug bites that cause severe itching, topical steroid creams or oral antihistamines may offer relief from itching and thus decrease the risk of infecting the bite site. When it comes to controlling bed bugs, do it yourself should not be anyones motto. Bed bugs are notoriously difficult to eradicate 76 percent of pest professionals say they are the most difficult pest to control. As such, people who suspect a bed bug infestation should turn to aqualified pest professionalwith expertise in treating these pests. The pest professional will evaluate the extent of an infestation and recommend the best course of treatment. In fact, the Centers for Disease Control and Prevention endorses that appropriate control of a bed bug infestation requires an experienced pest management professional and recommends that victims be advised against attempting to control measures themselves.

Bedbug bites: When bedbugs bite, you often see clusters of bites. Each cluster usually contains 3 to 5 bites that appear in a zigzag pattern. How do you know if you have bedbugs?

To find out if you have bedbugs, you need to look for two things:

Bites on your body: If you have bedbugs, youre likely to have bites. Bedbug bites usually cause itchy welts. These welts usually appear in a zigzag pattern as show in the photo above.

Youll seldom see bedbugs, so many people mistakenly believe that mosquitos, fleas, or spiders bit them. Sometimes people mistake bedbug bites for a common skin condition such as an itchy rash, hives, or chickenpox.

To make sure you have bedbugs, youll need to look for signs of bedbugs.

Although bedbugs dont usually require serious medical attention, they can cause a great deal of anxiety and restless nights. To help find bedbugs before they find you (and your belongings), dermatologists recommend looking for the following signs near places where you sleep.

Signs of bedbugs: This step is important. If you have a bedbug infestation, you need to find out so that you can get rid of the bedbugs. Getting rid of the bedbugs is the only way to stop the bites.

If you have a large number of bedbugs, you may see the bugs. Most people, however, only see signs of bedbugs. To look for signs of bedbugs, check the places that people sleep for the following:

If you see bedbugs, they will likely scurry toward the closest hiding place. Any dark place such as inside a mattress or even a picture frame makes a good hiding place.

As you watch bedbugs move, it can look like they are flying or jumping because they can crawl quickly. Bedbugs cannot fly or jump; they can only crawl.

If you find signs of bedbugs, call a pest-control company or your property manager. You should not use bug spray or a fogger. These products have little effect on bedbugs.

You should see a dermatologist for treatment if you have:

Your dermatologist may prescribe the following to treat bedbug bites:

Allergic reaction: Some people may require an injection of an antihistamine, corticosteroid, or epinephrine (adrenaline) for a severe allergic reaction.

Infection: An infection may require an antibiotic. If the infection is mild, your dermatologist may recommend an antiseptic medication that you can buy without a prescription. Your dermatologist will tell you which one to use. Your dermatologist also may recommend an antiseptic to prevent a skin infection.

Itch: A prescription antihistamine pill or liquid can help. You also can apply a corticosteroid to the bites. Your dermatologist will tell you which is best for you.

If you do not have any signs of an infection or a serious reaction, you can often treat the bites at home.

To treat bedbug bites:

Bedbug bites usually heal and go away within a week or two.
