Turns out, C. lectularius is also forming a resistance to other insecticides, according to a study published online April 10, 2017, in the Journal of Economic Entomology. The researchers, from Purdue University, found that three out of 10 bedbug populations collected in the field showed much less susceptibility to chlorfenapyr, and five of the 10 populations showed reduced susceptibility to bifenthrin, according to a post on Entomology Today. The scientists defined "reduced susceptibility" as a population in which more than 25 percent of the begbugs survived after seven days of exposure to the particular insecticide.


Just recently had my first experience w/ bedbug bites in Nicaragua. Hundred plus bites in one night and over a period of three days they became so inflamed, there were tiny blisters on each bite. These suckers snacked on me like I was an all you can eat buffet. I itched 4 days straight and finally went to a pharmacy there, which prescribed me acne creme. Worked, I guess, at least psychologically. But the bites kept festering more and more.
I had bed bugs last June (I live in Chicago and apparently bed bugs are a huge problem here). I’m dreading going through the whole process of exterminating them again. Do you know of any other kind of bugs that bite during the end of winter? Could these bed bugs be from last year? Maybe it’s a new infestation?? I’m going crazy over here! I don’t know what to do

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.

To avoid light, bedbugs hide in the seams of mattresses and crevices of bed frames, walls, and furniture during the day.5,7 They are attracted to human hosts by warmth and carbon dioxide; these hosts generally sleep within 3 to 7 feet (1 to 2 meters) of the bedbugs’ hiding places.8,9 Feeding usually takes place just before dawn.10 Bedbug saliva contains several anesthetic, vasodilatory, anticoagulant, and proteolytic compounds that allow the insects to feed undetected for five to 10 minutes. Three of these compounds have been identified as instigators of the subsequent hypersensitivity reactions that may be noticed when the host awakens.11–14

Claude suggested a “hot as you can stand it” shower or bath to treat the bites. The itching will intensify for a few seconds, but then there is the relief which lasts for many hours. Some believe that the heat from the water overloads the ends of your nerves and prevent them from telling your brain to itch. Some think that the heat causes your body to release more histamine than usual and thereby less histamine around the bite. Whatever the reason, it’s commonly used as a solution to itching caused by bites.
General housecleaning measures, (e.g. vacuuming floors and surfaces), seldom reach where bed bugs hide. For this reason, repetitive vacuuming by occupants may not be worth the effort, especially compared to other important preparatory activities. Targeted vacuuming of bed bugs and infested harborages, however, can help remove some of the bugs before other treatment measures are undertaken. Bed bugs and especially the eggs can be difficult to dislodge. Optimum results will be achieved by moving and scraping the end of the suction wand along infested areas such as seams and fabric folds of beds and sofas, and the perimeter edge of wall-to-wall carpet. Bed bugs can survive the high speed trip down a vacuum, so it’s important to carefully dispose of the vacuum contents in a sealed trash bag afterwards. 
Conventional insect repellents, like those used to deter ticks and mosquitoes, do not appear to be as effective against bed bugs. Therefore, attempting to avoid being bitten by applying insect repellent at bedtime is not recommended. Sleeping with the lights on is also not likely to deter hungry bed bugs, as they will adjust their feeding cycle to the host’s sleeping patterns. 
Summer means more time outdoors–and more opportunity for annoying critters to bite you. Most of the time, all you’ll get is a little red bump with itching and maybe a little swelling. These insect bite symptoms can be treated easily with anti-itch creams and over-the-counter antihistamines. Occasionally, bites can cause allergic reactions that lead to severe swelling and shortness of breath; if that happens to you this season, you need to be seen by a doctor.
I have no idea what works…. all the benedryl, cortizone, calamine lotion, and any cream/ointment said that they help with insect bites DOES NOT work. Once you start scratching, it’s over, you are going to scratch until the cows come home. If I am able to the trick is not to scratch at all. The enzyme is only released when you scratch, unless you are highly allergic like the picture that is show above, and I thought I was allergic, guess not.
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 use witch hazel with aloe vera (from Thayers). Apply with Q-tip or cotton ball. WORKS VERY WELL for me, especially when applied soon after bite is detected. Found that if it stings a bit when applied, it is likely that bite was recent, and more likely to reduce the itch. If I apply soon after a bite, I feel a little sting from the astringent, and the itch if often eliminated (although not sure how large the bugs are that bit me).


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.


No typically they do not like hair and actually prefer a host without hair (shaved legs etc). I would imagine this is one reason why we have hair on our bodies. However; this doesn’t mean that 1 or 2 wont get lost and end up in your hair. But typically they will not make that their place of rest or feeding. One thing I would like to advise is that for what I could imagine was quite some time these went unnoticed in my residence and have never caused me to itch, I would awake for work with my face being EXTREMELY PALE and a neck rash that I always assumed was from shaving also if goes unnoticed they must have been a factor in my bout of extreme depression / listlessness over the past few years. The cause…. According to the exterminator was the used furniture I got a too good to be true deal on at a garage sale for my first apartment, which he was even “nice” enough to deliver. He’s lucky he’s moved since than, lord knows what I would have done. But I will never forget his face.

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]
Many chemical pesticides are available, with more than 300 registered by the EPA. Pesticides should be applied to walls, floors, cracks in furniture, and seams and buttons of mattresses.21 The EPA’s Bed Bug Products search tool (Web site: http://cfpub.epa.gov/oppref/bedbug/) allows users to search by product name, company, EPA registration number, location of intended use, and pesticide type. The National Pesticide Information Center (Web site: http://npic.orst.edu/; telephone: 800-858-7378) is another useful resource. Silica gel dusts are a safer alternative to traditional pesticides, because they are less concentrated and less toxic.21 Plastic mattress and pillow encasements can help trap bedbugs and restrict spread.42 Regardless of the integrated pest management strategy used, a follow-up inspection 10 to 21 days after extermination is advised to detect and manage a persistent infestation.42

I don’t think my infestation is very extreme RIGHT NOW. i know for a fact they aren’t in or on the mattresses so that only leaves the crevices along the sides of the carpet. i got on my hands and knees to look but i still didn’t see anything. I KNOW THEY’RE THERE, WE HAVE THE BITE MARKS TO PROVE IT!!!!!! the little blood suckers are excellent at hiding.

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. 
No money whatsoever to do anything about it. I’m out of work and can’t even pay my rent. If we mention the infestation to the landlord he’ll toss us out because he’s in the process of selling the building. I’m going to try and go to an urgent care place to see if I can at least get something to stop the itching. This is driving me crazy with all the itching.
On Tuesday my arm became worse after spending the night at my friend’s place. At home, when I got out of the shower a bug near my jeans and killed it. I called my doctor to treat my arm and mentioned the bug. He saw me that day and put me on prednisone. Last night I took the antihistamine he prescribed, and it knocked me right out. I fell asleep on my friend’s shaggy carpet for about an hour and a half. As I awoke, I saw another bug run across my shorts.
I have very small red bumps on only one hand. Most of them skin color a few red. They don’t hurt and if I scratch them they itch a little bit mostly I don’t even notice they are there. They aren’t really in a line but I have probably about 6 or so on the top of my hand only. I searched my bed and all around it I find no trace of anything. I did read up and find that some bed bugs affect people differently and don’t show up right away. I have been sleeping on this mattress for over a month now and this just started happening for about 3 weeks. Am I just being paranoid or you think it sounds like bed bugs at all
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
Bedbug bite reactions are self-limited and typically resolve within one to two weeks without intervention.15 There is no evidence that any treatment alters the natural history of bedbug dermatitis.8 If pruritus is present, nonprescription topical antipruritic preparations containing the active ingredient doxepin, or intermediate potency corticosteroids may be beneficial. Mupirocin (Bactroban) and/or systemic antibiotics should be considered in the treatment of superinfected bites.8
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]
You can identify a bedbug infestation by checking bedding, mattress seams, furniture, and wall fixtures for the bugs or their traces. Each bedbug is about the size of an apple seed, about 1/4 inch long. You will often see their droppings instead, which are tiny brown or red specks. You may also see small blood stains on sheets or mattresses when a bedbug has been crushed after feeding. Eggs about the same size as the adults might be seen in seams or cracks and you will also see their molted exoskeletons.
Bed bugs often hide in seams, folds and crevices of mattresses, box springs, bed frames and headboards. A thorough inspection requires dismantling the bed so that upper and lower seams and surfaces can be examined. Things to look for are the bugs themselves, shed skins of the nymphs (immature bed bugs), and the blackish fecal spots. The dark spots of dried bed bug excrement are often present along mattress seams or wherever the bugs have resided. Box springs afford many places for bed bugs to hide, especially along the upper seams and underneath, where the bottom edge of the box rests on the frame. If an underlying dust cover is present, it may have to be removed to gain access for inspection and possible treatment. Successful treatment of mattresses and box springs can be difficult, however, and infested ones may need to be discarded or encased in a protective cover. 
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?
A common concern with bed bugs is whether or not they transmit diseases. Although bed bugs can harbor various pathogens, transmission to humans has not been proven and is considered unlikely. Their medical significance is most commonly attributed to itching and inflammation from their bites. Antihistamines and corticosteroids may be prescribed to reduce allergic reactions, and antiseptic or antibiotic ointments to prevent infection. Though not known to carry diseases, bed bugs can substantially reduce quality of life by causing discomfort, sleeplessness, anxiety, and embarrassment. According to some health experts, the added stress from living with bed bugs can have a significant impact on the emotional health and well-being of certain individuals. 

Bedbugs often invade new areas after being carried there by clothing, luggage, furniture or bedding. The creatures don't discriminate between dirty and clean homes, which means even luxury hotels can be susceptible to bedbugs. The most at-risk places tend to be crowded lodgings with high occupant turnover, such as dormitories, apartment complexes, hotels and homeless shelters.
Reports of bedbugs can be found in the popular press and on hotel and travel review sites, and they appear to be making a comeback. The good news is that they typically do not pose serious health risks, even though their bites may be uncomfortable. These slides show you how to recognize bedbugs, know where they're hiding, and learn what to do to prevent getting bitten.
You can develop a skin infection if you scratch the bites. Rarely, a more severe allergic reaction to the bites could produce larger welts, blisters, or anaphylaxis. Bedbugs may also trigger asthma attacks and getting too many repeated bites could lead to anemia. Anxiety, insomnia, and sleep disturbances are common due to the stress of discovering bedbugs.
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’ve been getting bites as well and I am extremely allergic. It is super itchy and now I have scars that will never go away. I am the ONLY one in my family getting bitten so no one understands my pain. I have 2 hours of sleep max at night because of both paranoia and getting bitten. I am up to the point that I cry almost every night from the pain. I’ve tried a lot of solutions, the one that is currently working for me is Vaseline. I apply several thick layers of the jelly and it stops the pain and itching. It also helped a lot with the swelling. I noticed it sped up the healing process a lot more than over-the-counter drugs that I’ve tried. I hope this helps!
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??
NEVER PUT ALCOHOL ON BEE STINGS OR WASP STINGS OR ANYTHING WITH A STINGER..it will force the venom into your blood stream and increase the danger, always use like Meat Tenderizer salt, toothpaste, and anything that draws out the venom from the skin. Use lemon juice, Aloe Plant, NEVER EXPERIMENT WITH TREATMENTS OF ANY KIND. i hope this helped. CHECK OUT YOUR LOCAL WHOLE FOODS STORES AND HERBAL STORES FOR HELP. BUY A BOOK ON HOME REMEDIES FOR INSECTS, GO TO YOUR LOCAL LIBRARY AND CHECK OUT BOOKS FOR HOME REMEDIES THAT ARE SAFE.
Hi, I’ve been in my apartment for over 8 years. We just had new neighbors move into our building. Now me and my children are getting bit at night by something. So, this morning, I was sitting on the couch in my bedroom and a bug crawled up my pants’ leg. I captured it in a plastic bag. I believe it’s a bed bug but is there a way to submit a picture to you, so you can take a look? Thank you!

I’m 19 years old; I Been staying at my aunts house for a while now and I just knows she has bed bugs; I always thought it was maybe a mosquito bite; but realized they aren’t put yet my arms stomach and back keeps getting bit I have ugly marks on my arms from this scratching I’ve Ben doing; it’s hidious… My question is how do I tell my aunt u have bed bugs without her being offended?


Objects or insects in the ear can be placed in the ear by patients themselves, or an insect crawling in the ear. Ear wax can also cause ear problems if Q-tips are overused to clean the ears. Symptoms of an object in the ear are inflammation and sensitivity, redness, or discharge of pus or blood. When to seek medical care for an object or insect in the ear is included in the article information.
Cracks and crevices of bed frames should also be examined, especially if the frame is wood. (Bed bugs have an affinity for wood and fabric more so than metal or plastic.) Wooden support slats, if present, should be removed and examined since bed bugs often congregate where the ends rest on the frame. Screw holes, knots and other recesses are also common hiding places. Headboards secured to walls should be removed and inspected. In hotels, the area behind the headboard is often the first place that bed bugs become established. Bed bugs also frequently hide within items stored under beds. 
The creatures don't have wings and they can't fly or jump. But their narrow body shape and ability to live for months without food make them ready stowaways and squatters. Bedbugs can easily hide in the seams and folds of luggage, bags and clothes. They also take shelter behind wallpaper and inside bedding, box springs and furniture. The ones that feed on people can crawl more than 100 feet (30 meters) in a night, but typically creep to within 8 feet (2.4 m) of the spot its human hosts sleep, according to the CDC.
A few decades ago, bedbugs were somewhat of a novelty in developed countries. But since the early 2000s, infestations have become more common in places like the United States, Canada, the United Kingdom and Europe, according to the U.S. Centers for Disease Control and Prevention (CDC). A 2013 study in the journal Nature Scientific Reports suggested that bedbugs have evolved ways to resist insecticides.
While you are sleeping, bed bugs will bite using their mouthparts, commonly referred to as beaks. As they bite, they release an anticoagulant in their saliva preventing your blood from clotting. This allows them to receive a steady two- to three-minute blood meal—what they need in order to survive and reproduce. Bed bugs will not bite in defense, they will only bite for the sole purpose of feeding.

just got back from two weekends of traveling to two diff locations. noticed a slight rash yesterday on the side of my ribs and a couple smaller itchy spots on one side of my stomach, etc. i don’t think it was from the first weekend of travelling as my bed companion didn’t get anything. the second weekend was at a college campus, but i had wiped the bed down before putting sheets and a sleeping bag over it. got back home sunday and noticed the itch yesterday (tuesday). so now i’m freaking out and assuming the worst scenarios. i’ve washed and dried all my clothes (though i did leave my suitcase out for two days before i even realized the itch), my sheets, and used a handheld steamer on my mattress, clorox / lysol the edge of my bed and the wooden frame, vacuumed all open areas on my wooden floor, etc. not sure if i should go to urgent care or what, but i’ve so far used hydrocortisone (previously already prescribed). can you please help or can i send you photos since you’re more familiar with this? never happened to be at home before all 20 something years so now i’m terrified i brought something back with me!

Traditional methods of repelling and/or killing bed bugs include the use of plants, fungi, and insects (or their extracts), such as black pepper;[54] black cohosh (Actaea racemosa); Pseudarthria hookeri; Laggera alata (Chinese yángmáo cǎo | 羊毛草);[15] Eucalyptus saligna oil;[55][56] henna (Lawsonia inermis or camphire);[57] "infused oil of Melolontha vulgaris" (presumably cockchafer); fly agaric (Amanita muscaria); tobacco; "heated oil of Terebinthina" (i.e. true turpentine); wild mint (Mentha arvensis); narrow-leaved pepperwort (Lepidium ruderale); Myrica spp. (e.g. bayberry); Robert geranium (Geranium robertianum); bugbane (Cimicifuga spp.); "herb and seeds of Cannabis"; "opulus" berries (possibly maple or European cranberrybush); masked hunter bugs (Reduvius personatus), "and many others".[58]
In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. "Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says. Those spots are left behind after a bedbug has been smashed.
