Often, bedbug bites are clustered along lines usually following arms and legs. Theories range from the idea that bedbugs are feeding along blood vessels to the idea that bedbugs remain with their bodies touching the bedding while they feed, and the bugs are left to feed only along lines where the skin is touching the bedding in just the right manner.
Hi Natasha !! I recently saw a bed bug crawling on my bed. So, I immediately cleaned all clothes in my room with hot water and put in high heat in the drier. I also sprayed the whole house with bed bug spray. Now on closer look of the mattress I found some bug remaining like its cover/shell, 2-3 blood stains but I did not find a colony/cluster of the bugs (which I was sort of expecting). So I bought a steamer and steamed my mattress and box spring. I also bought covers for the mattress and the box spring so that in case I missed any, they might get suffocated (at least I hope so). After all this, the next morning I woke up and found some sort of bite marks on my face. Also since I could not find any cluster of bugs, could they still be somewhere in my room ? where should I look for them ?
When people are bitten, they often do not notice at first. It’s a possibility that one reason could be that these blood sucking insects feed late in the night, before the breaking of dawn. Humans are often in a deep REM sleep during that time. Upon arising, individuals can find bite marks; however it can take up to ten days for adverse or allergic reactions to develop.
Medicated shampoos–both over-the-counter and prescription–can help get rid of them, as can combing and re-combing your hair carefully and disposing of the critters. If you do get head lice, don’t share anything that goes on your head (including hats, brushes, headphones, or hair accessories), and make sure you clean bedding and clothing that could have been infested in hot water.

Bed bugs are very resilient. Nymphs and adults can persist months without feeding which is unusual for most insects. The ability to survive without a blood meal is longer at cooler temperatures ― potentially up to a year or longer at 55°F or less. In temperature-controlled buildings, a more typical duration is about 2 to 6 months. Consequently, it is usually impractical to leave buildings unoccupied in hopes of ‘starving out’ an infestation. When infested dwellings such as apartments are vacated, bed bugs often disperse to nearby units, or reduce their activity until the unit is reoccupied. 
The bites usually last about 7 days, even if they are treated correctly. However, if you have sensitive skin like myself, they can last a couple weeks or in my husbands case, they last only a few days. As mentioned, if you scratch the bites its going to make things worse and besides running the risk of a bacterial infection, they will also take longer to heal so keep your nails away from them!
Three days after the initial “feeding” the sores hurt really bad. They itch like no other. By the way, none of my roommates have experienced this. I started panicking and washed all my clothes and sheets. I checked every corner of my room. Nothing. I couldn’t find anything, so them things must be hiding pretty well. Unless it isn’t bedbugs. Today I woke up and realized I had three more bites on my arm just above my elbow in the “breakfast, lunch, and dinner” pattern this site talks about.
Data Sources: A PubMed search was completed in Clinical Queries using the key terms bedbug, rash, bites, and infestation. The search included meta-analyses, randomized controlled trials, clinical trials, case reports, and reviews. We also searched the online databases of the Environmental Protection Agency, Centers for Disease Control and Prevention, and Jefferson Clinical Images. Lastly, we used Essential Evidence Plus. Search dates: February through June 2011.
Kept replacing the sticky traps just in case but never caught anything other than the occasional spider. Always cycled the sheets and such using the car+sun. They were still getting to us. Bed bugs cannot fly or jump. They had to be in the bed frame. I check it over and notice rusty spotting, which is apparently bed bug fecal matter. Luckily ours was from IKEA so it was easy to take apart – and sure enough – there they were. The way my bed works is a metal frame with holes, rubber end caps fit into those holes, and wooden slats run across the frame in the end caps. So every few days I’d mix up a 50/50 mix of bleach and water in a bucket and soak the wooden slats and end caps for ten minutes. The bed bugs were gone a couple of weeks and came back. I started soaking the things longer and scraping them with a disposable spoon, which was hard to do on the end caps. It warped the wood a little but nothing too bad. After a couple of weeks or so, I stopped finding bed bugs in the frame. I was worried they were in the metal too, but I completely stopped getting bites. I think the added time and scraping got rid of eggs. Not a lot can survive a 30 minute bleach bath.
Bed bugs are annoying insects that hide in soft, warm places like beds, couches, and clothing. These bugs feed on their hosts at night, leaving small bite marks that, though rarely dangerous, should be treated right away to prevent unwanted symptoms and potential allergic reactions. To prevent more bites in the future, you’ll need to get rid of your bed bug infestation completely.
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.
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.
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?
I have had one bite in threes which cleared up in days and an occasional acne looking sore on my but and arm. I have noted in my car lots of little bites but no marks. My son does not appear to have bites. once he had one on his back that cleared quickly. I really needs some help here as I am getting obsessive with cleaning and making my child change and bath. I have checked my cat for flees and bought her a flee collar as I am thinking the stinging bites I get in the day may be from flees but no itch or real marks. Help please.
It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.

I dont know if my post was received. I am using a phone its started acting weird and my comment was gone. My problem with bedbugs is so horrible I am trying again. I am 60 years old. I have never seen or even heard of someone having these creatures from hell.I am allergic to the bites. The red blotches quickly turned to deep red pus filled holes . Some arw very painful. I feel like my clothes have stickers in them. None of tje high priced insecticides for bedo bugs have did anything. I am actually losing it. I have used a lot of different chemicals because I am so terrible infected by their bite. I have not put a dent in the problem. I think I have poisoned myself. I have holed up in my bedroom embarassed of the bugs and the bjtes that cover my arms, legs back and toros. My son came by and I quickly rushed him outside. Completely puzzled he asked what’s is going on here ? I felt like the most horrible person. I just didnt want him to carry this curse home. I and in a hopess situation.
It’s been over a week since the first attack. I did not know where or when I got bit. Then a few days later in the night, I connected the dots. At 3 am I was up comparing bite pics on the internet and sure enough my fear was confirmed. I slept on the couch which is only 10 feet away in my studio with no problem. I did not see the actual bugs. I went and bought Steri-Fab spray–a gallon of it. I cleaned, vacuumed, sprayed the crap out of everything. I washed all my bedding in hot water. I threw out a throw rug. Sprayed baseboards again and around that side of the apartment.
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).

Conventional insect repellents, like those used to deter ticks and mosquitoes, do not appear to be as effective against bed bugs. Therefore, attempting to avoid being bitten by applying insect repellent at bedtime is not recommended. Sleeping with the lights on is also not likely to deter hungry bed bugs, as they will adjust their feeding cycle to the host’s sleeping patterns. 

I have what I guess can be described as a mild case of bed bugs in one of my cars, weird I know but in the process of taking care of it. Anyway I get bites around my elbows and it gets really itchy and bothersome for almost a week. What I found works wonders for me is simply taking 1000 mg of motrin once a day. I had a huge welt that looked swollen and red and taking motrin calmed it down and made it stop itching for almost a full day at a time.
In the lab we handle all the bed bugs in a specific room that we steam clean once a week, and we have double-stick tape barriers that they can't walk through (as long as the adhesive remains dust-free). And the bed bugs themselves are enclosed in containers that they can't get out of. We actually feed them inside those containers—we lay a blood reservoir against the cloth "lid" and the bed bugs have to push their mouthparts through the cloth into the reservoir to eat.
But the bites will look different from person to person, and some people won’t develop any reaction whatsoever. “The same bedbug could bite two different people and one could have no reaction at all and the other can have an extreme reaction with a swollen arm or itchy rash,” says Eric Braun, a board-certified entomologist and business manager for the national pest control company Rentokil Steritech, who is based in Redding, Pennsylvania. Some people end up developing a rash that looks like eczema. (5)
