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.
Once an infestation is confirmed, an integrated pest management strategy should be employed. Promoted by the Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention, an integrated pest management strategy is a multi-faceted, comprehensive strategy that relies on knowledge of bedbug biology and habits, and the most up-to-date pest control methods.3 An integrated pest management strategy minimizes economic, environmental, and health hazards, and is most effective for small bedbug populations.
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
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]
All of the stages of bed bugs are visible, at least if you don't need reading glasses and you have a sufficient amount of light. So if you're looking closely enough, you can even see bugs in the nymphal first instar stage. A fecal spot, for its part, can be as large as a bed bug itself in terms of the area it covers. The spots are basically digested blood, so most are dark in color. On a white mattress, they stand out pretty well.
If the bed bugs are coming from someplace other than your bed, I’d sprinkle uncalcinated diatomaceous earth around cluttered areas and the walls, and bleach the crap out of surrounding furniture. What the diatomaceous earth does is basically attach to their exoskeleton, dehydrate the insect, and they’ll either die of dehydration or get shredded apart as they crawl. Unless your pet or kid would directly eat the diatomaceous earth, it is safe to be in contact with since it’s not a chemical pesticide and it’s fairly cheap.
The diagnosis of a bedbug infestation should be based on the clinical history and appearance of bites. A thorough inspection of sleeping quarters by the patient, a family member, or a pest control expert may demonstrate the telltale signs of an infestation15 (i.e., specks of blood-tinged insect feces and exoskeleton casts [Figure 5]). With the aid of a magnifying glass, special attention should be given to cracks and crevices of furniture, baseboards, electrical boxes, curtains, carpet, luggage, bed frames and headboards, picture frames, wall hangings, mattress and box spring seams, peeling wall paper, clothes, and linens.37 Live bedbugs can sometimes be caught by turning on a flashlight just before dawn, when bedbugs are most active, larger in appearance, and slower to scatter because of recent feeding.40

I am freaking out. I woke up with one bump on my hand yesterday and tonight at about 2am i woke up with my hand itching again…there is a swollen lump about an inch away from yesterdays bump and then there are two swollen itchy lumps right by my wrist…there is also a swollen itchy lump on my chin… I am freaking out because i work in people’s homes so i always have this fear of bringing something home and recently a client hadn’t some bites on her back that looked similar to this. They went down as I rubbed alcohol. Ive had bites at a friends house similar to this n there are lots of spiders where she lives. It doesnt look like bed bigs but maybe some kind of house spider maybe getting to me at night(im in philadelphia). But again swelling and extremely itchy. I dont see bed big signs on my bed or anything can i email u a pic of my hand and face? I am itching so badly amd i cannot turn the lights back out and fall to sleep im paranoid. I cant stand any bugs.
Application entails treating all areas where the bugs are found or tend to hide or crawl. This takes considerable effort and follow-ups are usually needed. Companies typically treat seams, folds and crevices of bed components, chairs and sofas, but usually will not spray the entire sleeping surface or seating area. They also do not spray bed sheets, blankets or clothing, which instead should be hot washed or heated in a dryer. 

Hello all I just want to put this out there that heat is the best way to kill these little pests. I work for a company that uses heat to do structural pasteurization, in other words we heat the entire house up to 140°+ (which is higher than the the thermal kill point for bedbugs) for an hour or more (though they can only withstand that heat for less than 15 min) This has been the ONLY way to kill them with a 100% success rate since they are becoming resistant to chemicals and DDT is illegal. Some things work for some infestations but not for all, there are a lot of good ideas on here :-)
Well I had my house tented for bed bugs. It cost me $2600. My home is about 2000 sq ft. They said it wasn’t necessary to wash anything unlike some of the other treatments. It is more than worth it to me as long as it works. I haven’t stayed in my house for over a week now. I’m still itching, but no new bites. Is that common, to still itch for so long afterwards? I just don’t feel comfy/cozy at home any more. I don’t want to be here. I’m seriously thinking of selling or renting my home and moving out. I’ll keep you posted as to whether it worked or not as soon as I can start staying home again.

To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.
About a week ago I woke up with bites on my legs starting at my ankle up to my thigh. They were sparse but could be counted as grouped or lined. I have no bites anywhere else and have not gotten anymore bites since this happened. My husband shares the bed and our two small children (3 years and 17 months) are frequent bed joiners and none of them have any bites. I sleep with pj pants on and under blankets so it wouldn’t be the most exposed skin that I have at night. However I have no recall of being bitten and had pants on during the day. The bites were itchy for about two days and then they are just red. I am wondering if they could be bed bugs. I am having trouble sleeping because of the uncertainty. I have pics I could post.

We exterminated our old house,called junk to pick up our furniture (it wasnt lower end items either 8 year old $140,000 furnishings it cost) sold the empty home and hope they had no problem.. We did get the empty house exterminated and told the junk collection we had bugs,I bet they kept our old furnishings as it was beautiful stuff …It made us crazy,those damn bugs…One night 12 bites on my neck,forehead and hands !! I still feel like bugs are crawling on me,I think we need psychiatric care…It took about 1 year to get over the feeling of bugs crawling on us…
I’m suffering a similar problem. I had a friend who stayed with me on and off for a few months. She just didn’t tell me she had bed bugs right away. I had three kids and one on he way at the time. I bombed everything, threw out lots of things, and washed everything. Its now been a year and they’re back. Only now i have three kids and I have recently become the only income. Im barely holding rent and i don’t know what to do. I’m about ready to burn everything i own. I just can’t take it. I work 40 hrs., go to school, and have a child starting school in a week. Urgggg!!!!!!
Becoming a victim of a bed bug infestation is certainly devastating, but the public can rest easy knowing that these pests are not known to transmit any diseases. While it is true that some pathogens have been detected in and on bed bugs including hepatitis B, and exotic organisms such as Trypanosoma cruzi (cause of Chagas Disease, rarely found in the United States) or Wolbachia species, unlike mosquitoes and ticks, bed bugs have not been associated with disease transmission.
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. 
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.

Just wondering if it is unusual for bed bugs to bite where you are clothed? I have 3 bites, in a diagonal line on one side and in a triangle shape on the other side of my pelvic area both which are covered by underwear at night. Then I have a random spot here and there on my legs. We have a plastic mattress cover on our bed but use dark sheets. As best I can tell there is no evidence of bed bugs. What do you think? Thanks!


Some people develop allergic reactions to bedbug bites, which can include a fever, difficulty breathing, hives, or a swollen tongue. Others may develop an infection where the bite starts oozing pus. If you experience either of these reactions or you develop blisters where the bites occurred, it’s a good idea to make an appointment with a dermatologist.
