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
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]
Help!! I have had a long and exhausting experience with these nasty bugs. My mother in law had stayed at my house for a few nights and a few weeks later after returning home she discovered she had a severe infestation of bed bugs.. so of course I took precautions at my home thinking she gave them to me. I threw my mattress away then taped off my entire bed with very sticky tape. No signs or bites at all . Then a few weeks later my son started to sleep in his bed again and sure enough he woke up with 3 bites in the shape of a triangle that were swollen and itchy. I searched his bed and found a casing shell and 3 blood stains under his box spring .I called a exterminator he came out and said we had a mild infestation and there was no signs in my bed but he found one live bug in my son’s bed. He treated the bedrooms and living room. Then my son and i were getting these little bumps on our body that looked nothing like the triangle bites and didn’t itch so the exterminator came again and treated but found no evidence of bed bugs and this cycle happened four times! So he has treated my apartment 4 times and found no signs of bed bugs and even had a dog come out to sniff around .. this was all over the course of about 5 months . The exterminator insists that we do not have bed bugs anymore but my son is still getting these bumps on him, some are reds dots and some are skin colored but no complaining of itching . I’m very overwhelmed and exhausted and havery no idea what to think. I think the tape on my bed prevented them from getting back into my bed after I threw my mattress out but again the exterminator said tape does not work. Are they hiding somewhere else like in the walls to where the exterminator think the problem is gone ?
Bedbug bites typically are stealthy and not felt by the host. This is because they inject a numbing substance into the skin along with an anticoagulant agent to prevent blood from clotting at the feeding site. Itchy, red bites on the skin may be the first sign you've been bitten. Bites are most common on the arms and shoulders, and the bites often occur in straight rows, as pictured here.
Visit your doctor. You can also see a doctor for diagnosis if you do not find signs of bedbugs in your bed and cannot identify the source of the bites or rash. However, there is a very good chance that your physician will not be able to firmly diagnose that you have been bitten by a bedbug because the symptoms look so similar to those that result from other insect bites and skin conditions. Nevertheless, you may feel comforted by going to see your doctor, who can confirm for you that bedbugs pose little physical threat to humans.
This pair of bed bug bite photos below show the immediate (left) and next day (right) reaction after feeding a colony of bedbugs from a container in the lab. (That's why they are contained in a small circular area).  The hive-like immediate symptoms are replace by dark red rash type reaction the following day with inflammation and less severe redness radiating out to a larger area.  
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.
One thing I’ve noticed is my cat is unaffected by all this. I’m assuming I’m the tastier option of the two but I’m not discounting the fact she may be spreading eggs around my apartment. she has been carefully inspected from tip to tail with a nit brush and she has no bites, isn’t scratching and seems to be just as snug as a bug in a rug. To be precautionary I am going to begin dusting her with flea powder in the morning when i go buy some.
I recently flew on Airtran Airways, First trip I went well. flying back I had a 30 minute layover in ATL (not enough time to sit down). By the time I got home I was covered in bites from the back of my thighs to my neck. I counted over 100 bites! We have got a serious problem here. these bugs are on planes. I knew nothing about these bugs. Thank you for your stories and remedies. I won’t think twice next time they ask me if I want to upgrade to first class.

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).
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.
