A definitive diagnosis of health effects due to bed bugs requires a search for and finding of the insect in the sleeping environment as symptoms are not sufficiently specific.[5] Bed bugs classically form a line of bites colloquially referred to as "breakfast, lunch, and dinner" and rarely feed in the armpit or behind the knee which may help differentiate it from other biting insects.[4] If the number in a house is large a pungent sweet odor may be described.[4] There are specially trained dogs that can detect this smell.[2]

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.
Great stuff to use. My former girlfriend gave me a parting gift of bedbugs she got while staying at her parents house. She was good enough to leave me some cortisone though which I needed for the first time this morning. I had being seeing bedbugs and routinely treating them for about 2 months and I had laid diatomaceaous earth around my bed and didn’t have any itching or real issues. The layer had been wearing thin and I was too lazy to respreads. Last night I slept in the nude and woke up with the worst itching and now a rash all over my body. I had been seeing bedbugs and killing them for a month or two on and off and thought what’s the big deal. Now if know!!! This is the worst case of itching I’ve ever experienced!! Luckily I have the cortisone but it’s not helping too much. I’m blasting off a bed bug bomb my brother gave me 2 months ago that I never used and respreading the diamo earth. I checked my mattress and found literally only 2 bugs a very small nymph and an adult but they must be somewhere else because my body is covered in a rash. Maybe I finally reacted to bites I had been getting in the past or more are hiding elsewhere but I’m going to rid myself of these pests. Wish I could rid the world of them!!! This itching is the worst!!

Avoiding bed bugs is most challenging in hotels, apartment buildings, and other places where there are many people, high turnover and ongoing opportunities for introduction of the pests. Periodic, preventive inspection by tenants, housekeeping/maintenance staff, or pest control firms is the best way to detect infestations in their initial stages when they are easiest to control. Visual inspections can be supplemented by using various monitoring devices to capture and reveal bed bugs that may have been overlooked by occupants.   


The best way to confirm that the bites are from bed bugs is to find other evidence of a bed bug infestation. Common telltale signs can be found on or near your mattress: pull up your sheets and check the seams and folds for thin black fecal streaks or small red blood spots. You might also find bed bugs, living or dead, and their discarded shells in various hiding places, such as the joints of your bed frame.

Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
