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!
Bed bugs occur around the world. Before the 1950s about 30% of houses in the United States had bedbugs. Rates of infestations in developed countries, while decreasing from the 1930s to the 1980s, have increased dramatically since the 1980s. Before the 1980s they were common in the developing world but rare in the developed world. 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.

If you have bed bug bites, they may or may not look like the ones on the pictures. The bed bug bite pictures are meant as a guidance that should be used to eliminate other common insect bites. Please note that allergic reactions and a few other insect bites can look exactly like bed bug bites, so you shouldn’t make this your only step in identifying the bite. If you aren’t sure, contact your doctor and let him or her look at it. So what do bed bug bites look like? Have a look at the bed bug bite pictures below and see if they look similar to your own bites. If you have been bitten by bed bugs, then you should start bed bug bite treatment as soon as possible.
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
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
The first question I would ask that person is, what makes you think you have bed bugs? A skin reaction alone does not necessarily indicate the presence of bed bugs. Other bugs, allergies and irritants in the environment can produce similar skin reactions. And it's hard to confidently identify a bed bug bite because reactions vary from person to person. My next question would be, have you seen an insect in an area where you sleep and, if so, was it the correct size and shape to be a bed bug? Carpet beetles in an immature stage are commonly mistaken for bed bugs. The carpet beetle actually doesn't look anything like a bed bug, but it is the right size. And it's another common insect to have indoors around the bed. If you find an insect that you think is a bed bug, save it in a pill bottle or another container so its key characteristics won't get crushed and a professional can identify it.
As mentioned earlier, applying insect repellent at bedtime will probably not deter bed bugs from biting. When working in severely infested dwellings, there may be some benefit to spraying tops and bottoms of shoes with DEET-based repellents. Those working in bed bug-infested environments may also want to hot wash or run clothing, etc. through a dryer upon returning home or to the office.
No one tactic alone will be effective. A good pest control operator will develop a strategy to deal with the bed bugs that takes the particulars of the setting into account, and will return several times to check on progress. Dry ice sprays that freeze bed bugs have limited potential to reach hidden bugs. Steam has somewhat better penetrating ability. The downside of steam is that it leaves moisture behind. Dry ice doesn't leave any residue at all. Vacuuming has a role, but it has limitations, too. Some insecticides leave behind deposits that are slow to act but are effective in the long-term. Other insecticides kill on contact, but only reach insects that are in view. Insecticide resistance makes the choice of tactics more difficult.
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
Treatment is symptomatic. Eliminating bed bugs from the home is often difficult. Part of this is because bed bugs can live for a year between feeding. Repeated treatments of a home may be required. These treatments may include heating the room to 50 °C (122 °F) for more than 90 minutes, frequent vacuuming, washing clothing at high temperatures, and the use of various pesticides.
Although treating bedbug bites isn't difficult, actually getting rid of the bedbugs is another story. A professional exterminator can help. You will need to discard infested mattresses, box springs, and pillows. You can heat treat or cold treat items such as clothing by laundering or freezing. However, the room itself will need to be treated to eliminate bedbugs that can live in cracks in walls, floors, and furniture.
To avoid getting bed bugs while traveling, make sure to inspect the mattress and sheets on the hotel beds, especially near the seams, mattress tags, and box spring. If you see any rusty stains, dark spots, or pale yellow patches, this could be a sign of bed bugs. Also, never put your suitcase on the bed itself or you could bring them home after your vacation. Most hotels provide a luggage rack, which is much wiser to use.
We had bed bugs two years ago and I was hyper allergic. I’ve been paranoid every since. This morning I woke up with five marks on my stomach and am now terrified. When I got bit before it was my hands arms or face but it was my stomach… I wear guys shirts so my stomach was definitely fully covered. There have been zero signs for two years and suddenly five marks on my stomach. Is this some sort of rash or did they suddenly come out of nowhere within a night?
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. 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.
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.
