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.

The first thing is you have to be able to recognize and distinguish a bed bug from any other insect. Everything starts to look like a bed bug if you start to worry about them. An adult bed bug is about the size and shape of an apple seed. If it has not fed recently it will be flattened and brown. If it has fed it will be round in circumference and reddish. Immature bed bugs have a similar appearance to adults, with the smallest being the size of the head of a pin. You can then learn to look for their fecal spots, which can be easier to detect than the bugs themselves. Check your hotel rooms when you travel. And think twice before bringing home used furniture. If you are purchasing used furniture, ask the furniture store how they deal with bed bugs. If they have no plan whatsoever, that's probably not a good sign. If you purchase used clothing, put it through a clothes dryer on a medium to high setting for a cycle as soon as you bring it home. And before you move into an apartment, ask the landlord whether there has been a bed bug infestation, or whether the building has ever been treated for bed bugs.
Bedbugs bite and suck blood from humans. Bedbugs are most active at night and bite any exposed areas of skin while an individual is sleeping. The face, neck, hands, and arms are common sites for bedbug bites. The bite itself is painless and is not noticed. Small, flat, or raised bumps on the skin are the most common sign; redness, swelling, and itching commonly occur. If scratched, the bite areas can become infected. A peculiarity of bedbug bites is the tendency to find several bites lined up in a row. Infectious-disease specialists refer to this series of bites as the "breakfast, lunch, and dinner" sign, signifying the sequential feeding that occurs from site to site. In some people, the bites can take several days to develop. The signs may become apparent up to 14 days after the bite has occurred.

Mix 3 oz per gallon or 0.75 oz per quart and spray with a low pressure sprayer into the areas where the bed bugs are hiding. Typical areas include bed frames, headboards, under beds, baseboards, moldings, behind pictures,etc. Remember to apply in the joints and crevices of furniture. If the crack and crevice is too small, use an aerosol with a crack and crevice tip (recommendations are below.)
Diagnosing bed bug bites can be hard for medical professionals. We often hear of doctors assuming a variety of skin conditions before bed bugs – especially doctors who haven’t encountered patients with bed bug bites before. While there is no specific test to determine whether bites are from bed bugs there are tests that can show whether or not it’s an insect bite. This is useful for ruling out issues like eczema or allergic reactions, but not for determining that any specific insect bite is a bed bug. To be sure you’ll want to check for other signs of bed bug infestation, such as the bugs themselves, moltings, and the characteristic staining of their blood meal feces.
We’ve randomly gotten bites here and there but it’s summer so we were unsure. We had a cleaning lady come in recently and use her vaccuum so we suspect that could’ve brought in bed bugs! Last night was worst ever but I was outside yesterday but didn’t notice these bites til I just woke up. No signs of spots left behind on mattress, maybe one dot on bedding but could be anything. What do you think?? I have about 6-8 on my middle back and they are about an inch or so apart in one line across bra line area

I was at a friend’s house in the afternoon for 3.5 hrs and woke up at 3 am with severe itching, and pain, on my back. My entire back was covered in bites/rashes, clear lines and clusters. I had no idea what it was and went to the doc. Someone suggested shingles. Doc said definitely bug bites. I talked to my friend and they admitted to having seen bed bugs on the couch “recently.” Freaking out I flipped over my entire bedroom, found nothing. Washed the clothes I wore in hot water and high heat drier. I am hoping that the feeding occured during those few hours and no buggs travelled with me. All I had was me, no stuff. Can they “migrate” on people?


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. 
If the bed bugs are coming from someplace other than your bed, I’d sprinkle uncalcinated diatomaceous earth around cluttered areas and the walls, and bleach the crap out of surrounding furniture. What the diatomaceous earth does is basically attach to their exoskeleton, dehydrate the insect, and they’ll either die of dehydration or get shredded apart as they crawl. Unless your pet or kid would directly eat the diatomaceous earth, it is safe to be in contact with since it’s not a chemical pesticide and it’s fairly cheap.
Bed bugs typically feed at night when we are sleeping. Even though these pests commonly feed for 5 minutes, the bite itself is painless and usually goes undetected at the time. In fact, bed bugs inject an anticoagulant (a blood thinner) as they feed, which makes feeding easier for the bed bug and also less detectable to you. Although you may not see the bed bugs, or feel their bites, they know when you are around. Bed bugs are attracted to warmth and carbon dioxide. So, if you are alive, warm, and breathing - then you are broadcasting loudly and clearly to all nearby bed bugs that "dinner is served!"
Individual responses to bites vary, ranging from no visible effect (in about 20–70%),[5][3] to small macular spots, to prominent wheals and bullae formations along with intense itching that may last several days.[5] The bites often occur in a line. A central spot of bleeding may also occur due to the release of anticoagulants in the bug's saliva.[4]
Scratching can cause superinfection, leading to impetigo, cellulitis, or folliculitis.27–32 Reactions typically resolve within one to two weeks without treatment.32 Systemic reactions have been described, including asthma, generalized urticaria, angioedema, iron deficiency anemia, and, very rarely, anaphylaxis.33–36 Although bedbugs have been suspected to be vectors of more than 40 microorganisms, there is no evidence that they are involved in the transmission of disease.5

Another clue to infestation is odor. Like many species of bugs, bed bugs release odors called alarm pheromones. When a group of bed bugs gets disturbed, you may get a whiff of that odor, which is similar to the odor stink bugs give off. At higher concentrations the odor is unpleasant. Some people say at low concentrations it's a pleasant smell—like coriander. In fact, older literature refers to the bed bug as the coriander bug. I've tried to smell the coriander scent in bed bug alarm pheromones and have not been able to make the connection, however.


The bed bug is a universal problem yet it can be dealt with on a regular basis. used items and new items carry bed bugs. always wash and dry for 20 min. ( its the heat that kills the bug). bed pillows need to be washed and dried on a regular basis and the beds head board are full of body skin cells that attract the bugs. a good old cleaning with vaccum and wipe down is needed. keep your vac cleaned and bag empty after each use, the bugs are in the vac.
WHAT IS IT WITH THESE EU COUNTRIES - WHY ARE THEY SO SPINELESS? THEY ALL HAVE AN EQUAL VOTE YET THEY ARE ALLOWING JUNCKER AND BARNIER TO OBSTRUCTIVE AND DIFFICULT? WHO IS IN ULTIMATE CONTROL OF THE EU - THE MEMBER STATES OR THE EU COMMISSION? I VOTED TO REMAIN BUT I'M NOW GLAD WE'RE LEAVING - IT IS RUN BY DICTATORS IN BRUSSELS AND HAS GUTLESS WONDERS AS MEMBERS..............
Thank you all for the advice I’m seeing on here. Hydrocortisone was doing nothing for these bites. I have a high tolerance for pain but these bites really made me want to cry. I tried the Veeno Oatmeal bath, Witch Hazel and the Aloe Vera and this is when I began to get relief. These bites were very uncomfortable. I still itch a little but the swelling has gone down tremendously. I keep the Aloe Vera and witch hazel handy for the itching.

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.
Wash all the clothing that you brought home in a washing machine. Even clothes that you didn't wear must be washed in hot water. If you cannot wash something in a washing machine, you can either place it in a hot dryer or seal the items in a plastic garbage bag. If you seal items in a  garbage bag, leave the bag securely closed in an extremely cold or hot place for a few months.
First, there should be a thorough inspection of areas that may be infested to identify bedbugs. Once a room is identified as infested, don't remove anything from the room unless it is sealed in a plastic bag. Furniture and items that you want to discard rather than treat should be bagged and destroyed so other people don't use them. Call your trash collection agency to arrange for an immediate pickup. Reduce the clutter in the room and discard any cardboard boxes as they can harbor bedbugs. Vacuum the area and seal the vacuum bag in a plastic bag and discard it.
If you know that you have the bugs. Get sealing covers the kind that encloses completely, one for the mattress and one for the box spring. That will trap those critters inside and they will eventually die in there. Next you will need to decide of what combination of treatments you wish to use. Its a job that you will have to keep up with for some time. Do your research online first.
Blood spots found on one’s sheets, bites and the presence of bed bug feces and cast skins are some of the indications of a bed bug infestation. Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep – the hands, neck, face, shoulders, legs and arms. While not always the case, bed bug bites are often grouped together in a small area and at times may occur in a line or a zigzag pattern. Bites normally look like small, flat or raised areas that may become inflamed, itchy, red or blistered. Bed bug bite reactions don’t always appear immediately after you’re bitten and may take a few days to begin causing symptoms. However, not everyone reacts to bed bug bites in the same manner.
