Bed bug bites are caused primarily by two species of insects: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] They are about 1 to 7 mm in size.[7] Spread is by the bugs walking between nearby locations or 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 locations like mattress seams or cracks in the wall.[2]


No two people react to bites in the same way, although some reactions are similar. Because of the saliva that they leave behind, the first reaction is usually severe itching and irritation. This is often followed by a raised appearance on the contacted area. Some people, however, react by having welts and hives all over the body. Still others will have small, pinkish bumps that are concentrated in one area.


Bedbugs are small oval-shaped non-flying insects that belong to the insect family Cimicidae, which includes three species that bite people. Adult bedbugs reach 5 mm-7 mm in length, while nymphs (juveniles) are as small as 1.5 mm. Bedbugs have flat bodies and may sometimes be mistaken for ticks or small cockroaches. Bedbugs feed by sucking blood from humans or animals. Cimex lectularius is the scientific name for bedbugs.

The bites do not usually require medical treatment. Secondary bacterial infection of the skin may develop in areas that become irritated due to prolonged scratching. Topical antibiotic creams or ointments may relieve symptoms of a secondary infection. Antiseptic lotions may also be beneficial. If you've had an allergic reaction to the bedbug bites, your doctor may recommend oral antihistamine medications or corticosteroids.
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.
Mix 8 ml (about 1/3 oz)(measurements on the bottle) or one 8 ml vial of Temprid FX with one gallon of water. 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.
Bed bugs occur around the world.[36] Before the 1950s about 30% of houses in the United States had bedbugs.[2] Rates of infestations in developed countries, while decreasing from the 1930s to the 1980s, have increased dramatically since the 1980s.[3][4][36] Before the 1980s they were common in the developing world but rare in the developed world.[4] The increase in the developed world may have been caused by increased international travel, resistance to insecticides, and the use of new pest-control methods that do not affect bed bugs.[37]
I spent the night at my boyfriends house 5 nights in a row, knowing that his family owns a couch infested with bed bugs. I find it weird that I’m the only one, out of 7 family members, that gets bit by the bed bugs! Its crazy! I get bit during the day when I sit for a few mins, or even sleep on the bed at night, but it still baffles me that I’m the only one who is suffering from the itch of the bites. My son who I share the bed with does not get bit at all, which is great, but I’m curious, “why only Me?”
We had bed bugs two years ago and I was hyper allergic. I’ve been paranoid every since. This morning I woke up with five marks on my stomach and am now terrified. When I got bit before it was my hands arms or face but it was my stomach… I wear guys shirts so my stomach was definitely fully covered. There have been zero signs for two years and suddenly five marks on my stomach. Is this some sort of rash or did they suddenly come out of nowhere within a night?
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). 
To prevent bringing bed bugs to one's own home, travelers are advised to take precautions after visiting an infested site: generally, these include checking shoes on leaving the site, changing clothes in a garage before returning to their home, and putting the used clothes in a clothes dryer outside the house. When visiting a new lodging, it is advised to check the bed before taking suitcases into the sleeping area and putting the suitcase on a raised stand to make bedbugs less able to crawl in. "An extreme measure would be putting the suitcase in the tub." Clothes should be hung up or left in the suitcase, and never left on the floor. [29] The founder of a company dedicated to bedbug extermination said that 5% of hotel rooms he books into were infested. He advised people never to sit down on public transport; check office chairs, plane seats and hotel mattresses, and monitor and vacuum home beds once a month.[30]
Many news reports in recent years have focused on the discovery of bedbugs and their health effects (even in upscale five-star hotels), and a number of lawsuits have been filed by guests of fashionable hotels who awoke to find hundreds of bedbug bites covering their skin. Searching on travel-review web sites regularly reveals information and even photos confirming the presence of bedbugs in numerous hotels.
8 days ago my friend & i decided to crash at my grandmas house after a wild night out. in the morning we woke up in horror seeing how they freely crawled all over her mattress cover. Within the last 7 days, bite marks have been appearing all over my body, i am practically covered; as to my friend, well lucky her she has only 3 on her arm. The problem isn’t only that i have more bites than her but i believe i have an allergic reaction, the bites have massively grown in size. I do not know what else to try, Calamine doesn’t work, baking soda with water made it worse, Benadryl hasn’t done anything either. I am at a point where i am about to cry. The worst part is that in less than a month I am going on my first tropical vacation. I simply cannot handle the stress, i suffer from mild anxiety & these massive rashes have turned these 7 days into hell. I have stopped scratching because it seems to irritate the bites. Please help.
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
Hey I went to visit friends this Saturday and Sunday. Saturday I slept fine Sunday I slept in a different location, I kept feeling bites but was unsure through the night. I woke up the next morning with red bumbs like two clusters of three and four on one arm, four on my other arm not far apart, four on my leg, three on my lower back. As they day went by they got bigger like lumps and really itchy, I had benedryl and creme I could not sleep last night at all. Some of them hurt a bit I try not to scratch them. Ooh and three on my face, my skin is very sensitive, my friends sat on the same chair I sleep on noone got bit. How long does the itching last, Iaautomatically knew it had to be bed bugs does it sound like them??
Hello, i was worried that we had bed bugs in our room and i hired an exterminator to come in and have a look. He said there was no evidence of bedbugs. And also because the bites were really only on the torso. Regardless, a few months later we had the opportunity to change the entire bedroom set and cleaned all the sheets on sanitize cycle – the bites all went away. Now, however, about 6 months later they seem to be coming back. Does this sound like a bed bug issue to you? If so, now what should we do? I cant but another bedroom set.
During the day, bedbugs tend to hide away in furniture, floors, beds, and in wood or paper trash. They typically feed on human or animal blood at night, and most bites occur just before dawn. After taking their meal, which can last as little as three minutes, they drop off the host and crawl to a hiding place. Bedbugs can live for up to 10 months and can go without feeding for weeks.
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.
thank you natasha! i’ve reached out to both locations i’ve traveled to and they confirmed their pest control vendors have found nothing. and i had a visual/dog inspection from a reputable pest control company to check my entire house and they’ve found nothing as well. so hopefully this is just a one off and / or mosquito bites that just like biting in a line…can’t help but still be paranoid and sleep bundled up with socks
When staying in a hotel, I check the bed before I bring the suitcase into the sleeping part of the room so that if I have to ask the manager for another room, then I haven't exposed my suitcase to the bugs. When settling in, I put my suitcase up on the suitcase stand or the desktop so that any bugs are less likely to crawl into it. An extreme measure would be putting the suitcase in the tub. If it's a porcelain tub, bed bugs would have a hard time crawling up it. It's also unlikely that they would randomly crawl up a tub, because it's not near the bed. But if I don't see bed bugs in the room when I inspect it, I just put my suitcase on the stand because I know the probability is really low that a bug is going to crawl up the stand and into my suitcase. I keep my clothes in the suitcase or hang them in the closet—I don't leave them on the floor because wandering bed bugs might crawl into them.
This morning, I stood in front of the mirror for my daily grooming routine when the most gruesome red bumps appeared before me and it’s at the side of my neck! Thankfully it’s Saturday coz I will not spend my time with my co-workers! I researched and stumble upon your website. I wish you could help me The bites are getting itchy and what would you recommend? Natural or modern medicine? Thanks i’ll be waiting for your answer…
Wash all things washable and leave in HOT dryer for at least 20 minutes. The old timers used to sun dry and air their hand made quilts outside in the sun all day and bring them in before the dew would start to settle. they also did their mattresses and pillows and cushions and this must have heated up things a bit but be careful that the sun doesn’t fade the color.
In most infestations, consultation with a professional exterminator is advised because elimination is more likely to be effective if multiple pest management methods are used. These include monitoring devices, canine detection, clutter removal, vacuuming, heat or cold treatment, sealing cracks and crevices, and judicious use of nonchemical and chemical pesticides. Monitoring devices include moat-like devices (e.g., Climbup Insect Interceptor) that trap bedbugs ascending and descending furniture legs, and emitting devices that use carbon dioxide, heat, and/or chemicals (e.g., Nightwatch monitor) that attract and trap bedbugs. Specially trained dogs are reported to detect bedbugs with 97 percent accuracy and are able to differentiate live bedbugs and viable eggs from debris remaining from previous infestations.41 Vacuuming is a highly effective method for removing bedbugs, but not eggs because these adhere to surfaces.42 High-efficiency particulate air filters eliminate bedbug allergens and debris.42  Nonchemical treatments include petroleum jelly (which can be applied to legs of furniture to prevent bedbugs from ascending), heating, and freezing (see Table 36 for effective killing temperatures).
The bed bug is a universal problem yet it can be dealt with on a regular basis. used items and new items carry bed bugs. always wash and dry for 20 min. ( its the heat that kills the bug). bed pillows need to be washed and dried on a regular basis and the beds head board are full of body skin cells that attract the bugs. a good old cleaning with vaccum and wipe down is needed. keep your vac cleaned and bag empty after each use, the bugs are in the vac.
A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. The National Institutes of Health recommend about 7-9 hours of sleep each night for older, school-aged children, teens, and most average adults; 10-12 for preschool-aged children; and 16-18 hours for newborns. There are two stages of sleep; 1) REM sleep (rapid-eye movement), and 2) NREM sleep (non-rapid-eye movement). The side effects of lack of sleep or insomnia include:
I sleeped over my boyfreinds house just for a night my 4month old daughter and I slept on the bed and we got bit bad but my poor baby seems to have pus on her bites..she got bit even on her face her fingers etc..but funny thing my boyfreind didnt get bit, I got home and i washed everything we took in hot water dried in hot washed my beeding all her blankets the car seat was left out in the heat for 2 days..then i washed it in hot water i vacumed the whole room sprayed alcohol on the carpet on my matress..question is what more can i do? is there any chance that they could still be in my room?
Luckily, I just discovered this website giving great advice regarding all the pink, itchy bumps and welts on some parts of my body – and I never experienced problems with bed bugs before until now! So far, I’ve only seen one. But, I’m blessed to already have many of the home remedies for cleaning my sofabed, where I got bit from the bug(s), and started working on treating the irritating bites. I hope to get back to let everybody know how things go.
Firstly, its important to remember that, despite their daily diet of blood, bed bugs will not transfer blood based diseases (such as AIDS, etc.). However, in very rare cases, these bites have been known to cause Anaphylaxis, which is an adverse allergic reaction that covers the entire body in a rash. After being bitten by a bed bug, be alert for any of these potential complications:

I woke up this morning trying to figure out what’s this pain on my back and sadly I found out it was munched by a bed bug! It’s so gross and I don’t want my girlfriend to see it!  Can an antibiotic cure me from these bites? I only have antibiotics here and the nearest mini convenience store is 5 kilometers away so yeah help me please! Thanks Natasha!
I dealt with these creatures for over 7 months. thought I was going crazy. 3 doctors- allergist-GP, dermatoligist. was treated for scabies as well. every day 2-3 new bites. some days none. i did the diaclamateous earth- alcohol- website bed bug kikkers. Finally, I actually saw 3 in a box. then i called an exterminator- for bedbugs. showed him the box he came 4 times – every sat for a month. something to do with how they reproduce. luckily this was a good man and he charged 300.00 and guaranteed it. i ripped out the carpet- the baseboards- everything in my room. only saw maybe 20 bugs in total. he said i had been treating them so that was why there were so few. Finally they are gone- 2 months now. I was the only one getting bitten- my husband did not until the very end and not nearly like me. The drs do not know for sure what the bites are when we go. and when we traet ourselves we kill them… but they hatch and are not gone. Had I known i would have gladly paid the 300 in the 1st place as these things nearly made me crazy. Just my story
While encountering bed bugs in hotels is possible, typically only a small number of rooms have problems. If bed bugs are discovered, guests can request another room, preferably in another area of the building, since problems often extend to nearby units. Should you experience itchy welts suggestive of bed bug bites during your stay, it would be prudent upon returning home to place all clothing directly into the washer and/or dryer. Inspecting or vacuuming luggage upon arrival home is less useful since it’s hard to spot bed bugs inside a suitcase. The suitcase itself can either be treated or discarded.

Its important to note that bed bugs can easily be transferred from other locations (such as hotels, friends, etc.) into your bedroom, something your definitely want to avoid! Its important to always check your skin, clothing and bags for any signs of bed bugs (and their bites) before entering your bedroom after sleeping away from the home. If you have been bitten a couple times, there is usually no urgent need for medical care. In fact, there are a number of effective home remedies that you can use to treat these insect bites. However, sometimes medical assistance is required. When is this the case and how can you identify when professional help is needed?
I too feel hopeless about the bed bugs, I clean scrub and now have noticed them on the mattress, walls, picture frames and just the other day on my laptop!! I’ve tried so hard to get rid of these animals and haven’t been able too, my arms and hands feel like I have small pox these things can get really annoying the itching never stops I’ve tried aloe and calamine and it’s just getting worse. I’ve spent sleepless nights looking for them and I haven’t been able to get rid of them
Did you or someone else in your home recently come home from a trip? Bugs can stow away in clothing and in the recesses of your luggage. A good preventative measure is to check lodging you are staying in immediately after arrival. As mentioned before, signs are evident, even during the daytime, include the blood-colored excrement they leave behind.
Data Sources: A PubMed search was completed in Clinical Queries using the key terms bedbug, rash, bites, and infestation. The search included meta-analyses, randomized controlled trials, clinical trials, case reports, and reviews. We also searched the online databases of the Environmental Protection Agency, Centers for Disease Control and Prevention, and Jefferson Clinical Images. Lastly, we used Essential Evidence Plus. Search dates: February through June 2011.
Bed bugs infestations can be treated by pesticides (make sure it specifically treats for bed bugs) or call a professional. Clean laundry and bedding by washing in hot water and drying with high heat. Steam cleaning can be effective, but be sure to check for bugs in a week or two. Concentrate in the areas they like to hide such as the seams. Bed bugs are sensitive to heat, so putting your mattress in a tight plastic bag and leaving it in the heat for several days can kill adults and the eggs. Vacuum your mattress and the areas around it. Be sure to immediately empty the vacuum cleaner and throw it out. If your mattress is infested, you may also consider getting a new mattress, but be sure to take care of the rest of your home so that your new mattress doesn’t get infested.
Thank you so much for all the information. I just found a bed bug in my room at 5:00 AM in the morning. I have been getting these red itchy rashes for more than 2weeks . It’s extremely annoying and in spite of looking every where , I couldn’t find anything. These Biggs are so difficult to find. Now after reading this I feel they are even more difficult to eradicate.

I recently flew on Airtran Airways, First trip I went well. flying back I had a 30 minute layover in ATL (not enough time to sit down). By the time I got home I was covered in bites from the back of my thighs to my neck. I counted over 100 bites! We have got a serious problem here. these bugs are on planes. I knew nothing about these bugs. Thank you for your stories and remedies. I won’t think twice next time they ask me if I want to upgrade to first class.

I’ve cleaned the entire area…this time sprayed it all down with a bedbug killing spray (Raid). Everything, nooks, crannies, corners, the vent. I’ve also re-inspected my spare mattress. No sign of anything. I’ve gone as far as going into both. the inside of my boxspring has been saturated with the raid spray as is the “down” side of the mattress. I slashed into the side of the mattress and sprayed inside there too. I am going to be mopping with bleach in the morning and afterward I will do my spray down again.

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]
I just moved into my new apt with my 1 yr old and 3 yr old sons. the first night we slept on covers on the floor until i got the beds in. that very first morning there we woke up with bite marks on us. i thought maybe they were just mosquito bites or something. after the beds got in we continued to have this problem. poor kids cant play right from the itching. I’m pregnant so when the bites we on my stomach i went crazy especially since i worked so hard not to scratch and cause stretch marks.
First and foremost I think the wisest course of action to take is to get rid of your bed. the whole shebang…the mattress and box spring and all your linens, blankets, pillows and articles of clothing you use to lay in bed with (robes, pajamas and underwear). It’s just not worth it. Get a temporary air mattress for a few weeks if need be. You will be better off in the long run.
my concern is i am homeless and staying at a mission for now downtown Seattle there are thousands of these things in our city and biting a lot of sick people …”CAN YOU GET AIDS FROM A BED BUG???”i guess this is a major concern for a lot of people and how do we go about eliminating them in our city???..what do we put on the bites or do we just leave it alone???

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.
Bedbugs are a species of insect known as cimex lectularius (literallycimex is Latin for bug and lactularius is Latin for bed). There is a second common species of bedbugs known as cimex hemiptera. These are known as the tropical bedbugs, staying within 30 degrees of the equator. There are published reports, many without supporting evidence, that each of the common bedbug species has chemically different saliva. Some researchers, however, have found no difference in the reactions caused by each species.
Im staying with these people in another town going to school I am mid fifties, I always bring home like these brown bag like “dinners” my room got infested with ants and I cleaned it up, ever since then i have developed these very sore 1/4 in bumps on back near my right armpit its also very major on the back of my upper arm, it dose not itch but is sore, What the heck is it! Should I be concerned,Will it go away!Should I get some benedryl?My friend said it will go away in five days or so,Any suggestions?

If all other options have been exhausted, you may need to seek a professional PMP (Pest Management Professional). There are pesticides that are approved for professionals to use during a infestation. These pesticides, however, are not always effective, and typically not as effective as steam cleaning, excessive heat, or excessive cold. The exterminator may opt to treat the area with carbon dioxide.
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.
Bedbugs are most often found in hotels, hostels, shelters, and apartment complexes where lots of people come and go. Because bedbugs hide in small crevices, they can hitch a ride into your home on luggage, pets, furniture, clothing, boxes, and other objects. Bedbugs are found worldwide, but are most common in developing countries. Once rare in North America, they may be on the rise due, in part, to increases in international travel.
