Cutaneous reactions to bedbug bites can vary widely and are easily confused with other conditions (Table 1).15–19 A typical lesion is a 2- to 20-mm, pruritic, erythematous maculopapule with a central hemorrhagic crust or vesicle.5,8 Macules, papules, wheals (Figure 3), vesicles, bullae, and nodules have all been reported,20 as have asymptomatic lesions with a barely visible punctum as the only evidence of a bite.8 Bites vary in number and are preferentially distributed in unclothed areas (e.g., face, neck, extremities). Unlike many other arthropod and insect bites, bedbug bites are rarely located in the popliteal fossae or axillae.21 Lesions can be noticeable immediately when waking up or several days later, with the reaction often progressing from delayed to immediate with subsequent exposures22–26  (Table 2). The classic bedbug rash is referred to as “breakfast, lunch, and dinner” because it commonly presents as several bites in a row or cluster 20 (Figure 4).
Bed bugs are small, brownish, flattened insects that feed solely on the blood of animals. Although the common bed bug (Cimex lectularius) prefers feeding on humans, it will also bite other warm-blooded animals, including dogs, cats, birds and rodents. It has done so since ancient times; bed bugs are mentioned in medieval European texts and classical Greek writings back to the time of Aristotle.
Hi can you respond to me privately? I inspected my bed mattress and linens for any signs of bed beg fecal matter and any grown bed bugs or spots of feces. I have not found any traces blood-type residue or brownish type feces in the mattress. Is it normal to find an occasional bites from something other than bed bugs? Sometimes after shaving, I will have red pimples where I have shaved.

Adult bedbugs are reddish brown in color, flat, oval-shaped, wingless and approximately 4-5 millimeters in length. Immature bedbugs (nymphs) may be translucent or light tan in color and therefore very difficult to see. Bedbugs are often more red in color after feeding. Bedbugs are attracted by warmth, and they generally feed during the night, often just before dawn. They tend to feed every five to 10 days, though they can survive without feeding for several months. Bedbugs pierce the skin and inject saliva that contains anesthetics and anticoagulants into the host, which often make their bites painless initially. After feeding on the host's blood for several minutes, bedbugs will crawl back to their hiding place. They will generally try to hide and remain within close range of their warm-blooded host. Affected individuals may feel and see the consequences of the bedbug bite afterward, though many individuals will not develop any physical signs of a bite. Bedbugs do not transmit or spread human disease.
Bed bug bites occur most frequently while you’re asleep. As bed bugs bite they inject their victims with an anesthetic (as well as an anticoagulant), numbing the area and making it very rare for someone to wake up when bitten. Bites normally take a day or two to appear, although depending on your individual reaction they may be more visible sooner.
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.

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 know when you get infested with these, the bedding and mattresses all have to go. We are just barely scraping by as it is, and we have a bed for each kid no matter how often they come to see us – including ours, that’s SEVEN mattresses and bedding sets. Our landlord is not returning our calls, and although I know that he is responsible for not treating the problem which (per neighbor reports) the previous tenants had, too. But the lawyer wants $500 to even send a LETTER, let alone go to court. And I keep thinking that even if we go to court and win, the courts will make him treat the apartment…not replace the furniture that’s effected because of it. So…we sleep on floors, with newspapers?
Not sure how we got it since we never go anywhere. Been dealing with this for almost a year. I have terrible bites, scars, scabs and bumps all up and down both hands and arms. Have a bite on my cheek and some on my neck. Hubby has bumps that you can’t see, but you can feel them. I am going crazy itching. I don’t like leaving the house because of how I look. I use cover up and foundation on my hands to mask how bad my hands look. I wear a long-sleeved, summer weight sweater to hide the mess on my arms. Plus I can pull the sleeves down to help cover some of my hands.
In addition to the physical manifestations of bedbug bites, patients can experience significant psychological distress. The stigma that bedbugs are related to poor hygiene (however inaccurate) can lead to poor self-esteem, avoidance of family and friends, and suspension from work.37–39 Management of an infestation can be stressful, costly, and disruptive to everyday life. Worry can lead to insomnia, depression, anxiety, and even delusional parasitosis.37
Bedbugs can live in any area of the home and use tiny cracks in furniture as well as on textiles and upholstered furniture as hiding places. They tend to be most common in areas where people sleep and generally concentrate in beds, including mattresses or mattress covers, box springs, and bed frames. They do not infest the sleeping surfaces of beds as commonly as cracks and crevices associated with the bed frame and mattress. Other sites where bedbugs often reside include curtains, edges of carpet, corners inside dressers and other furniture, cracks in wallpaper (particularly near the bed), and inside the spaces of wicker furniture.
Thanks so much to the person who mentioned the hot/cold water method! I think when you do it when you first notice the bites, It will keep them from becoming huge, itchy welts! I run hot water over the bites and I feel a sense of relief, as if I’m scratching the bite, without actually scratching it. The area turns pink, and I keep going until the relief sensation has subsided, then I run cold water over the area. Works great and it does last for hours!
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.
Bed bug incidents in schools are best handled by knowledgeable pest control firms. Widespread insecticide treatment of classrooms, hallways, buses, etc. is unnecessary, ineffective and imprudent. Effort instead should be spent checking chairs, desks, lockers, coat rooms, etc. in the vicinity of where the bugs were found, and treatment should be focused on those specific areas. Canine inspections can also be useful in finding small numbers of bed bugs in schools and other establishments where there are no beds.      
Dusts have been used to ward off insects from grain storage for centuries, including plant ash, lime, dolomite, certain types of soil, and diatomaceous earth or Kieselguhr.[60] Of these, diatomaceous earth in particular has seen a revival as a nontoxic (when in amorphous form) residual pesticide for bed bug abatement. While diatomaceous earth performed poorly, silica gel may be effective.[61][62]

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.

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.


Bed bugs are challenging to eradicate. Since they can hide in so many places, inspections must be thorough and elimination is not always a certainty. Whenever resources allow, it’s prudent to enlist the services of a professional. Experienced pest controllers know where to look for bed bugs, and have an assortment of tools at their disposal. Nonetheless, owners and occupants can assist the professional in several important ways. Affording access to all living areas is crucial, and excess clutter will need to be removed. Belongings strewn about rooms offer many places for the bugs to hide, and impede inspection and treatment. Since bed bugs can disperse throughout a building, it often will be necessary to inspect adjoining rooms and apartments as well. 
Don't assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It's best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.
