Chances are, you or someone you know has had a run-in with bed bugs. It might have happened in a scrupulously clean bedroom. Or maybe it was a hotel room, office or college dorm. In the February issue of Scientific American entomologist Kenneth Haynes of the University of Kentucky explains how, after a lengthy absence, bed bugs are staging a comeback. The good news is scientists are intensively studying these insects, and their insights suggest novel ways of detecting the bugs and eradicating infestations. Some of those potential solutions are a long way off, however. In the meantime the best bet is to avoid bringing bed bugs home in the first place. I called Haynes to ask him how to do that and what to do if one suspects an infestation (eek!), among a bunch of other practical-minded questions.
This pair of bed bug bite photos below show the immediate (left) and next day (right) reaction after feeding a colony of bedbugs from a container in the lab. (That's why they are contained in a small circular area).  The hive-like immediate symptoms are replace by dark red rash type reaction the following day with inflammation and less severe redness radiating out to a larger area.  
Bed bugs hide in seams of mattresses, box springs, bed frames, headboards, dresser tables, inside cracks or crevices, behind wallpaper, or any other clutter or objects around a bed during the day. Bed bugs are transmitted from place to place as people travel. They can be in the seams and folds of luggage, overnight bags, folded clothes, bedding, furniture, or anywhere else they find a place to hide.
Another solution you hear about is vacuuming. You can vacuum up a lot of insects, but eggs are harder to get, and vacuuming won't in and of itself kill bed bugs. Indeed, vacuuming can end up spreading bed bugs to other rooms—when emptying the canister, for example. Pest control operators who use vacuums take measures to prevent bed bugs from escaping when the vacuum is emptied.
Amazingly, these sneaky little bloodsuckers dine on you without waking you. You don't feel their stealthy bite because they inject a numbing agent into your body, along with an anticoagulant to keep your blood flowing as they suck. The first sign of bedbugs may be itchy, red bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites.
High there I’ve been looking on the net for a while now about pictures on the marks I have now I know full well bed bug bites come on the arms, neck, face etc but I have marks on my chest, stomach, arms, legs, and a couple on my face but the thing is some of them look like zits but the others don’t and they keep coming I do in fact have sensitive skin too but people think I’m crazy because of my speculation to bed bugs I do feel pricks on my skin so its not just because I have sensitive skin there’s something else that’s making it go so much more crazy but I do know better some of the marks has an blood mark others with swelling others with swelling with the blood mark on the tip top as an example the marks many of them look like the (Many Small Bite Marks) picture but all over my body. please help I’m losing a lot of sleep because of this ordeal.

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.
Heat treatment: Heat of 120 F for two hours will kill bedbugs. Wash items in hot water (120 F or above). This may not be enough, though, so it's recommended that you place items in a clothes dryer on hot heat for at least 30 minutes. In a hot climate, you can bag items in a black plastic bag and leave them in direct sunlight for 24 hours. For travel or home use, there are portable heating units that can be used for clothing and luggage. A garment steamer can also be used on some items, such as luggage.
If you know that you have the bugs. Get sealing covers the kind that encloses completely, one for the mattress and one for the box spring. That will trap those critters inside and they will eventually die in there. Next you will need to decide of what combination of treatments you wish to use. Its a job that you will have to keep up with for some time. Do your research online first.

use advantage plus on your cat or frontline plus its cheaper..you cannot get rid of fleas with a flea collar & they are actually very toxic & dangerous to your cat & your child..i had almost killed my cats using over the counter flea treatments when my whole house was infested because of a neighbor and we had bought the over the counter flea dips & my cats were shaking & having seizures & the over the counter variety of advantage or frontline i think it was called zodiac they sold it to me telling me its cheaper than a vet bill for the prescription & just as effective..my cat almost died..thats when we took it to the vet because it was deathly ill from that posion..stick to the prescription brands you can even buy them on ebay or online shipped from overseas w/o a prescription thats how i used to buy them..now my new cat never goes outside & our dog & cats never catch fleas here but i sure remember what a living hell that was & how i almost killed my cats & my KIDS with the toxic posions they sell you in stores & these flea bombs..i had been using them weekly so now ihope i didnt give us all cancer or something those chemicals are neurotoxins to humans and animals.its well worth the $10 the frontline or advantage plus costs..the fleas die within a day or so & that kills the eggs and keeps them from hatching & the plus also protects against mosquitoes & ticks that may carry diseases.


A deterrence for them that we’ve found, as well as the bleach, is lavender. Blood sucking bugs don’t seem to like it too much. I don’t personally like it because the lotion that we have makes my skin itch, and I’d rather just deal with the bites since my reactions aren’t so bad to them. However, the lavender lotion has been seemingly working, at least a little bit, for my mother and sister. Although this is the case, I wouldn’t recommend it for anyone. It’s okay to use, but it doesn’t seem to be too strong at keeping them away.
Hello! I am not sure if we have bed bugs or not. It seems like I am the only one getting bit. We co-sleep with our children and neither of them have signs of any kind of bites. I wake up with bite marks underneath my breasts and sometimes behind my knees. The bites itch for only a few minutes and disappear a few minutes after. We have looked through our mattress and have found no signs of anything. No blood smears nor any fecal matter. Could my bites be caused by something else.
Scratching can cause superinfection, leading to impetigo, cellulitis, or folliculitis.27–32 Reactions typically resolve within one to two weeks without treatment.32 Systemic reactions have been described, including asthma, generalized urticaria, angioedema, iron deficiency anemia, and, very rarely, anaphylaxis.33–36 Although bedbugs have been suspected to be vectors of more than 40 microorganisms, there is no evidence that they are involved in the transmission of disease.5
Items that cannot be placed in a washer or dryer can sometimes be de-infested by wrapping them in plastic and placing them outdoors in a hot, sunny location for at least a day (for example, on pavement or in a closed vehicle parked in the sun). Packing items loosely in garbage bags and elevating objects off the ground helps the heat permeate further, and will make it harder for bugs to find a cool place to hide. Monitoring with a thermometer is prudent to ensure that a temperature of at least 120°F is achieved wherever the bugs may be. 

I moved into my apt in April and started getting bitten in June , my apt have been professionally treated 3 separate times. I have a 3 year old and I’m so worried for her she doesn’t seem to get bitten or if she is she doesn’t have the bad reaction that I do which is good. I have 18 bites in the past week the worst I’ve ever had. I can’t find the little blood suckers but I found a bed bug spray at home depot. I’m going to treat my house wash and dry all my clothes in hot temps , then caulk every crack and crevice in this apt. I plan to do this every week until my lease is up and I can move out this apt 7 more months.


My boyfriend is staying with a man who rents a room out in his house. The last tenants had bed bugs and the living room couch and everything is infested and theyve been gone for a month. The bugs were dormant until a week or two ago. The man has sprayed the house with something that is supposed to kill bed bugs yet my boyfriend is continuously being bitten. We counted around 100 bites. They are swollen and the itching is making him crazy. He is unable to sleep at night. We are trying to convince the man to just throw the couch out. Since he has no carpet we believe the couch is their main breeding ground and the sprays DID NOT WORK.
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.
One trick to make this disposal easier involves using the cut-off end of a nylon stocking (or a knee-high nylon stocking) and a rubber band. Insert the stocking (toe first) into the end of the vacuum suction wand/tube, leaving the opening of the stocking protruding out of the end of the suction wand. Then fold the stocking opening back over the end of the wand and use the rubber band to secure it there. When the vacuum is turned on and the bed bugs are sucked into the tube, they will be trapped in the stocking. Afterwards, carefully remove the rubber band and retrieve the bug-filled stocking. Then secure the end of the stocking with the rubber band and dispose of it. 
We have already replaced are furniture, threw out our bed that we still haven’t be able to afford to replace I have treated the house daily with sparaies and powders. We have torn up our carpet one three rooms of the house. Did all that before getting new furniture but yet we still can’t seem to rid of these bedbugs. The infestation doesn’t seem to be as bad, yet we are still getting bitten nightly by them we don’t have a lot of money we are struggling the way it…help what can I do

When traveling, inspect the bedding prior to exposing yourself or your belongings. Seal your dirty clothes in plastic bags. You may even consider encasing your luggage in a plastic bag while you are in a hotel room. Launder your clothing as soon as you get home. You can treat your suitcase by vacuuming, using a clothes steamer, or handwashing it with hot water and soap. You might also consider encasing luggage in a plastic bag between trips.
Both of these types of Hemiptera are sensitive to extreme temperatures. It may be necessary to rid the infestation by exposing the area to extreme heat or cold; they are most comfortable in temperatures around eighty degrees Fahrenheit. Raising the temperature to ninety-seven to ninety-nine degrees may kill off a significant portion of the population.
According to textile experts (Drycleaning & Laundry Institute, Laurel, MD), most garments designated as ‘dry-clean only’ (e.g., cotton, wool, silk, linen, rayon, nylon) will not be harmed provided they are dry before being placed in a clothes dryer at a moderate temperature setting. Dry cleaning procedures also kill bed bugs, but there is a risk of infesting the establishment when buggy items are tagged and sorted. 
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.

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.


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 the lab we handle all the bed bugs in a specific room that we steam clean once a week, and we have double-stick tape barriers that they can't walk through (as long as the adhesive remains dust-free). And the bed bugs themselves are enclosed in containers that they can't get out of. We actually feed them inside those containers—we lay a blood reservoir against the cloth "lid" and the bed bugs have to push their mouthparts through the cloth into the reservoir to eat.
Bedbugs are found in temperate and tropical climates worldwide. The insects are most commonly found in living quarters where their host resides. Bedbugs generally hide in the seams and crevices of bed mattresses and box springs, bed frames, headboards, upholstery, old furniture, closets, and in spaces underneath baseboards or behind loose wallpaper. Clutter and disarray also provide additional hiding places for bedbugs. Bedbugs may be transported from one location to another via luggage, furniture, clothing, and used mattresses. Although they are often associated with unsanitary living conditions, bedbug infestations also occur in clean, well-maintained living quarters, including five-star hotels and resorts. Bedbug infestations have been increasingly reported in hotels, dormitories, homes, apartments, nursing homes, cruise ships, shelters, jails, and hospitals. There have been several cases in the U.S. involving litigation because of infestations of bedbugs, and thus bedbugs are considered a public health pest by several agencies.
Bedbugs are obligate blood parasites that belong to the insect family Cimicidae. Cimex lectularius and Cimex hemipterus, the two bedbug species that feed primarily on humans, are oval, reddish-brown, flat, and wingless. Adults are typically 4 to 7 mm in length (Figure 1). Nymphs can be as small as 1 mm, and are translucent and lighter in color 5,7 (Figure 2). Adult females produce 200 to 500 eggs in a typical six- to 12-month life span.5,8 Bedbugs can withstand temperatures from 44.6°F to 113°F (7°C to 45°C).8

I recently just got bed bugs from my room mates moms house and the pain is so bad it to me feels like there’s poison in my stomache and it sucks. i have done the benadryl spray didn’t work the only thing that i been doing that helps with the itch is the rubbing alcohol, but the thing is it works but for like ten mins and that’s it. Tonight i am hopefully hopping to try the lime thing and see how it goes will keep an update.
About five weeks ago bed bugs were found out work, then two weeks ago they spread, pest control has seen continuously coming to check and yesterday they gave the place the green light. I work with a largely indigent populace, the office I work at was not sprayed, during the night at some point, I will feel painful stings, hours later I have been finding small lumps or even large and hard ones, Could it be bed bugs? There is a particularly painful lump on the back of my thigh, it’s very hard too.
How to treat and prevent chigger bites A chigger is a form of mite that feeds on human skin cells. Although they are so small that the naked eye cannot see them, chiggers can inflict extremely itchy bites that can last up to a week without treatment. Here we look at how to avoid getting bitten as well as how to recognize and treat any existing bites. Read now
