Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals.[4][16][17][18] Cimex lectularius only feeds every five to seven days, which suggests that it does not spend the majority of its life searching for a host. When a bed bug is starved, it leaves its shelter and searches for a host. It returns to its shelter after successful feeding or if it encounters exposure to light.[19] Cimex lectularius aggregate under all life stages and mating conditions. Bed bugs may choose to aggregate because of predation, resistance to desiccation, and more opportunities to find a mate. Airborne pheromones are responsible for aggregations.[20]

The bites of bedbugs can be difficult to identify, and not all red bites are due to bedbugs. Mosquitos, fleas, biting gnats, and mites can all bite humans. Collecting and identifying the bugs can help establish the diagnosis. They can often be found beneath or on the seams of mattresses. Their bloodstains may be visible even in the absence of bedbugs. You should also look into nooks and crannies of furniture, walls, and floors if you're suspicious that bedbugs may be present.
I was in europe and have always been healthy and felt fine the 2 months while there, on my drive back home I started itching my arm and didn’t think much of it. During the next few days to weeks the itching turned into welts that itched like crazy and got bigger and harder within hours. The redness would then extend out apx. the size of a 50 cent piece that would form a small scab in the middle as it would heal. Then it would heal , but the next few welts would appear in different places. They would start off as itchy flat red circles that would quickly become firm and red. I sometimes would also feel stings all over . I’ve had this problem now for over a month. One dr. told me I had mites, another said I had bed bugs. I have small scars all over my body now. I used the all over cream 4 nights ago that is supposed to kill mites. The itching is still there but not quite as bad today and yesterday. I’ m going for a third opinion tomorrow. I never knew that itching can keep me from working or actually doing anything else except for keeping calamine lotion beside me and rubbing it on me every 10 minutes. Good luck to all of you that are dealing with the same nightmare.
That's very possible. I have heard of couples reporting that only one partner is getting bitten. The truth is that both are getting bitten, but only one has a reaction to the bites. Thirty percent of people or more don't react to bed bug bites at all, and the elderly are less reactive than the rest of the population. Among those people who do react to the bites, most of them don't respond to early bites, but develop a sensitivity to subsequent ones. Those individuals who are not sensitive to bed bug bites may not know they have an infestation. Because bed bugs are nocturnally active, it's hard to see other signs of their presence—unless you're accustomed to waking up at 3 A.M. and taking a census. With a huge infestation, bed bugs start to move away from the bed, so you're more likely to see one in an exposed place during the day. In very severe infestations people can become anemic. That takes a lot of bugs though—maybe 100,000 feeding once a week or more.
As bed bugs grow they molt, shedding their skin five times before reaching maturity. A blood meal is needed between each successive molt. Adult females also must feed in order to lay eggs. Under favorable conditions (70-80°F), the bugs can mature fully in as little as a month, producing multiple generations per year. Cooler temperatures or limited access to blood prolong the development time. 
Likewise, if I get bitten by a bed bug, I usually get a rather bad rash which is extremely sensitive to touch while they are hardly visible on my husband. If your bites become very itchy, you need to resist the urge to scratch the affected area as this can make the problem worse and cause further inflammation, infection or even bleeding. According to the Center for Disease Control, bed bug bites can even cause insomnia due to the fear of being bitten. This can result in a lack of energy and dramatically increased anxiety levels.

Hello! Almost overnight I have had a series of small bumps appear on my chest. These bumps look like pimples and they don’t itch at all. I had bed bugs well over a year ago and once they were treated I never saw anything except these bumps recently. My sister thinks I’m just being paranoid because we’ve both checked the bed and saw no signs. And because my chest is always covered, but my arms and legs that are are exposed never have places. I realize that I’m probably being paranoid, but I just wanted an outside opinion.

As if you needed something else to worry about, bedbugs, those pests from the old bedtime rhyme are making a comeback. More of a nuisance than a health hazard, they’re showing up to suck blood from people in hotels, college dorms, and hospitals. Take an informative look at bedbugs: what they are, where they lurk, and how to spot them before they get you.
