"We originally thought the bedbugs might prefer red because blood is red and that's what they feed on," study co-author Corraine McNeill, an assistant professor of biology at Union College in Lincoln, Nebraska, said in a statement. "However, after doing the study, the main reason we think they preferred red colors is because bedbugs themselves appear red, so they go to these harborages because they want to be with other bedbugs, as they are known to exist in aggregations."
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.
Bed bugs occur around the world. Before the 1950s about 30% of houses in the United States had bedbugs. Rates of infestations in developed countries, while decreasing from the 1930s to the 1980s, have increased dramatically since the 1980s. Before the 1980s they were common in the developing world but rare in the developed world. 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.
I thought I was getting bitten by mosquitoes when out on my balcony. But I get bitten during the night and basically on the arm outside of the covers. This all started after my neighbors in the apartment next door moved out. I have yet to actually see the bugs. The bites tend to be in a line which I read online was typical for bedbugs but not always.
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).
With practice and a flashlight, nonprofessionals can become proficient in finding and destroying bed bugs. The process is made easier by reducing clutter, especially in bedrooms and sleeping areas. Bugs that are spotted can be removed with a vacuum (see previous discussion), or killed with over-the-counter insecticides labeled for such use. Most bed bug sprays intended for householders have little remaining effect after the spray has dried. Therefore it’s important to initially contact as many of the insects as possible with the spray droplets. Insecticide labels should be read carefully as some bed bug products should not be used on mattresses and seating areas. Some insecticides applied as powders or dusts (e.g., diatomaceous earth) will kill bed bugs although boric acid powder will not. However powders can be messy and difficult to apply, especially by nonprofessionals. Total release foggers (otherwise known as ‘bug bombs’) are ineffective against bed bugs and potentially dangerous when used incorrectly (see University of Kentucky entomology fact sheet Limitations of Home Insect Foggers).

Hi, I am from the United states and have recently travelled to Poland. Decided to stay in an AirBnb in Warsaw. Everything was okay until a couple of days into the stay when I noticed what seemed like a very small cluster of small bites in the crook of my neck. Stranger still, on the opposite side of my neck, in the same location, there was another very small cluster of small bites. Ofcourse, I panicked. Washed everything three times, etc. The next few days, it seemed a couple of more would appear in the same area. In the crook region of my neck. But, NOT on my legs, feet, stomach, hands. Keep in mind, I sleep with very little clothes and thought it was weird that this “skin reaction” was not any where else. I did start wearing a new product in my hair and exactly where my hair falls usually, is pretty much where these little “bumps” appeared. I did try to do little experiments to test out the theory that I may just be having a skin reaction to a hair product. One night, after donning almost little to nothing sleepwear, I rubbed lemon juice all over my neck. The next morning, I did feel slightly better but I believe maybe one or two very small bites after I washed it. Lately, I’ve been securely wrapping my neck and covering it when I go to sleep and have recently stopped using said new product in my hair. The bumps seem to be darkening and going away and as usual, found nowhere else on my body. Occassionally, after running the crook of my neck area, it feels like one or two very small bumps will appear. I dont know. Is this a new level of highly sophisticated bed bugs that I’m dealing with? Or is it just a skin reaction and my mind is playing invisible bug warfare on me? Please note. I do not have lice and these very small bumps I mentioned before are way further down from my scalp. Crook of neck area. Just a little higher than where my collar bone is. Please advise. Have you heard of anything like this?
In comparison to other insect bites, bed bug bite marks are usually in groups of three or more when they appear on the skin. This is sometimes called the “breakfast, lunch and supper bites”. As you can see in the picture below, the bites are rather close to each other. Their bites often look like little red bumps, pimples or even blisters and welts. Some people can also mistake them for flea bites. If one of these insects bite you, you usually won’t even feel it as it uses a form of anesthetic which dulls the pain. Bed bugs also are known to leave bite marks in a straight line, also in close proximity to each other. A single bed bug can bite you a number of times during the night. However, if you have a bed bug infestation, there are usually a large number of these little pests and this can result in a multitude of bite marks. Please also remember that some people may not have a negative reaction to these bites. In fact, sometimes they are mistaken for spider bites, even by medical professionals so make sure you let your doctor know if you feel it could be a bite from bedbugs. Lastly, you will be happy to learn that bed bugs do not fly so you won’t be attacked from the air.
i kno what most of yall ppl saying ….i recently stood over a friends house and my bestfriends brother bed was infested but i never knew it was so we bunked together. I stayed over ther for 3 days. The friday i came home stayed in for the weekend and bam monday morning woke up outta my sleep with the most painful itching ever! it got bad within hours
They’re just redbugs or chiggers.. I get them every year. I’ve lived here in SC my whole life and I have to deal with em every year about this time (late spring/early summer). Do not scratch them ! otherwise, you’ll get a nasty spreading rash ……… use alcohol or hydrocortisone cream …….don’t scratch, I know it’s hard ! you’re daughter probably has the most sensitive skin, hence the worst reaction to the bites.
All these bed bugs can be dealt with. it is best to use a non chemical treatment to make it safe for your environment . here is one i found, food grade Diatomaceous Earth found at garden centers, follow instructions, and move beds away from the walls, sprinkle in the carpet deeply, on to base boards , ( it works like borax powder for fleas and roaches) .
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.
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.
Bring a little flashlight—hotel room lighting is always pretty poor and the dimmer the lighting, the harder it is to see small bed bugs or their fecal spots. I would pull back the bed covers and look all around the head of the bed. Pull back the sheets, too, and look at mattress seams and edges that are exposed. bed bugs love to hide under mattress tags. Look all around the box springs, too. If there's a dust ruffle, pull it up and look under it as much as possible. Look for moving bugs and stationary, hiding bugs.
Hey Ruth! If there are absolutely no signs of bed bugs (upon close inspection), its unlikely that they are the cause for the bite marks. I recommend taking another look for dark brown marks (dried blood) and other signs of their presence. Regardless, if you want to kill any bug on that mattress, just get a handheld steamer and blast it. The heat will kill everything and its completely natural. Hope that helps!
"In the past, bedbugs have repeatedly shown the ability to develop resistance to products overly relied upon for their control. The findings of the current study also show similar trends in regard to chlorfenapyr and bifenthrin resistance development in bedbugs," study researcher Ameya Gondhalekar, research assistant professor at Purdue's Center for Urban and Industrial Pest Management, said in the Entomology Today statement. "With these findings in mind and from an insecticide resistance management perspective, both bifenthrin and chlorfenapyr should be integrated with other methods used for bed bug elimination in order to preserve their efficacy in the long term."
Found worldwide, bedbugs are most common in developing countries. Still, reports of bedbugs in luxury hotels are not uncommon. They are most commonly found in areas like hostels, hotels, shelters, and apartment complexes where there are many visitors coming and going. When they enter your home, it's often because they have hidden in luggage, furniture, clothing, or boxes that are being moved. They can also travel on pets' fur. Increases in international travel may be responsible for the rise in bedbug sightings.
Bed bugs usually bite people at night while they are sleeping. Hungry bed bugs may also feed during the daytime, especially if this is when the occupant normally sleeps. They feed by piercing the skin with an elongated beak through which they withdraw blood. Engorgement of the bed bug takes roughly three to 10 minutes, but because the bite is painless, the person seldom realizes they are being bitten. Bed bugs normally do not reside on people like head or body lice do; instead, immediately after feeding, bed bugs crawl to a secluded location to digest their meal. Symptoms after being bitten by bed bugs vary from person to person. Many develop an itchy red welt within a day or so of the bite. Others have little or no reaction. Sometimes the reaction is delayed days or even weeks after the actual bite occurs, which can make it difficult to determine where or when bites actually occurred. Studies conducted in bed bug-infested apartments suggest about 30 percent of people do not react even when bitten repeatedly over time, and there is still higher incidence of non-reactivity among the elderly. Unlike flea bites, which occur mainly around the lower legs and ankles, bed bugs feed on any skin exposed while sleeping (face, neck, shoulders, back, arms, legs, etc.). The welts and itching are often wrongly attributed to other causes, such as mosquitoes. For these reasons, infestations may go a long time unnoticed, and can become quite large before being detected.
Some preparation is still required (e.g. removal of heat-sensitive items such as aerosol cans, indoor plants and medications), but it is seldom necessary to bag, launder and/or hot dry bedding and clothing since these items will be heated along with other furnishings. Another advantage of heat treatment is that infestations can often be eliminated in one day, rather than over multiple days or weeks. Conversely, heat treatment alone has no lasting (residual) effect should bed bugs be reintroduced into the dwelling. Consequently, some companies recommend concurrently applying residual insecticides. To further minimize reintroduction, occupants are advised to take as few belongings as possible with them while the heat treatment is in progress.
