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.


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.
A few decades ago, bedbugs were somewhat of a novelty in developed countries. But since the early 2000s, infestations have become more common in places like the United States, Canada, the United Kingdom and Europe, according to the U.S. Centers for Disease Control and Prevention (CDC). A 2013 study in the journal Nature Scientific Reports suggested that bedbugs have evolved ways to resist insecticides.
The safest and most effective approach to getting rid of bed bugs is heat treatment, in which a trained professional heats the home's rooms one by one to a temperature of 50 degrees Celsius and sustains the heat for four hours. Heat does not penetrate well into wall voids, though, so desiccant dusts are often applied to those areas. No single technique can eliminate bed bugs—combinations of approaches are essential to getting the job done.

Bed bug bites are caused primarily by two species of insects: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] They are about 1 to 7 mm in size.[7] Spread is by the bugs walking between nearby locations or being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high density areas.[8][2] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark locations like mattress seams or cracks in the wall.[2]


We recently moved to Chicago into an apartment building. AFTER signing the lease the landlord told us that he sprayed for bed bugs every 3 months…I guess I thought this was precautionary? It wasn’t. I am apparently allergic to these bites, my husband & son, thank god, are not affected. So far nothing helps me with the itch for more than a minute but I just found this sight so hopefully something will work. We have bug bombed and bug sprayed with no luck. Washing everything helps for maybe a day? Tonight we sprayed bleach ALL OVER our mattress and attacked it with a blow-drier. Also, I’ve slathered myself in baby oil per a post here.
Chances are, you or someone you know has had a run-in with bed bugs. It might have happened in a scrupulously clean bedroom. Or maybe it was a hotel room, office or college dorm. In the February issue of Scientific American entomologist Kenneth Haynes of the University of Kentucky explains how, after a lengthy absence, bed bugs are staging a comeback. The good news is scientists are intensively studying these insects, and their insights suggest novel ways of detecting the bugs and eradicating infestations. Some of those potential solutions are a long way off, however. In the meantime the best bet is to avoid bringing bed bugs home in the first place. I called Haynes to ask him how to do that and what to do if one suspects an infestation (eek!), among a bunch of other practical-minded questions.
Bed bugs will also succumb to cold temperatures below 32°F, but the freezing temperatures must be maintained for a longer period (e.g., one to two weeks). Consequently, heating tends to be a better option throughout much of the country. Efforts to rid entire dwellings of bed bugs by raising or lowering the thermostat will be unsuccessful, although pest control firms are able to achieve lethal temperatures with supplemental heaters (see the subsequent section entitled "Heat Treatments" for more details). 

Luckily we were at the tail-end of our trip and once I arrived back home I immediately soaked in a hot-hot Epsom Salt bath. I used 3 cups of Epsom Salt, repeated that twice…and shazaam! The bites reduced in size and the itch was “almost” completely relieved. I had an extremely severe reaction going on and at one point considered going to a dermatologist or hospital to get some professional care.

WE have been dealing with these pests for over a month now! WE are covered with welts and itch continuously. I tried bathing in shaving cream and get some relief. the shaving cream has a disinfectant in it that purifies the skins and relieves itching for several hours. I still find a stray bed bug every now and then but we have almost got the problem solved.

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?

These things are the real vampires!!!! Just got bit over my eye, which now is all swollen and hurting, and 3 bites on my upper arm, caught the 2 little bugs on the wall next to my bed. Make sure that your bed is away from the walls. I use tea tree oil it helps to calm the itching down, I have a bad reaction to them. Not sure where the keep coming from and always in twos. Ahhhhhh!!!!!!! Can’t sleep

Some pest control firms utilize specialized heating equipment to de-infest furnishings, rooms, and entire dwellings. The procedure involves heating up the infested item or area to temperatures lethal to bed bugs. Portable heaters and fans are used to gradually heat the air to about 120 - 130°F while monitoring with strategically placed sensors. By carefully controlling the temperature, bugs and eggs are killed wherever they may be without damaging household items. 
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?
Pulled back the sheet and sure enough there were bugs. I saw 2, but I believe there were more. I killed the two then he went to report it to the front desk and they did nothing about it. We checked out the next day and i did not have a reaction until 3 days later after we left for Orlando. Went to the pharmacy, got lanacane oinment and other meds for the itching. Its been 2weeks since the bite and I’m still itching like crazy. Luckily I came on this site and i tried the baking soda paste and it seems to be working. I also used the witch hazel and will try raw aloe also. I hate to little black bugs.
Bed bugs have five immature nymph life stages and a final sexually mature adult stage.[13] They shed their skins through ecdysis at each stage, discarding their outer exoskeleton.[14] Newly hatched nymphs are translucent, lighter in color, and become browner as they moult and reach maturity. Bed bugs may be mistaken for other insects, such as booklice, small cockroaches, or carpet beetles; however, when warm and active, their movements are more ant-like, and like most other true bugs, they emit a characteristic disagreeable odor when crushed.
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.
Flea bites are caused by the parasitic insect, the flea. The most common species of flea in the US is the cat flea, Ctenocephalides felis. Signs and symptoms of flea bites in humans include itching, hives, a rash with bumps, red spots with a "halo," and swelling around the bite. Treatment for flea bites includes over-the-counter medicine and natural and home remedies to relieve and soothe itching and inflammation. The redness of a flea bite can last from a few hours to a several days.

Bed bug infestations have resurged since the 1980s[43] for reasons that are not clear, but contributing factors may be complacency, increased resistance, bans on pesticides, and increased international travel.[44] The U.S. National Pest Management Association reported a 71% increase in bed bug calls between 2000 and 2005.[45] The number of reported incidents in New York City alone rose from 500 in 2004 to 10,000 in 2009.[46] In 2013, Chicago was listed as the number 1 city in the United States with the worst bed bug infestation.[47] As a result, the Chicago City Council passed a bed bug control ordinance to limit their spread. Additionally, bed bugs are reaching places in which they never established before, such as southern South America.[48][49]
Bed bug bites can leave you with painful inflammation and since they love to hide in beds, you may be bitten a number of times before you wake up in the morning! If you have a severe allergic reaction, its recommended that you seek professional medical assistance as soon as possible. Besides medical creams and pills, things like tea tree oil, baking soda and even lemon juice can also give you relief at minimal cost. I highly recommend that you try these first as they work really well.
Very helpful article, plus everyone’s comments. I wish you all the best of luck with bedbug problems. We went to a cabin near Yosemite before Christmas and I saw bugs on the bed. Luckily we didn’t sleep there and left right away. However I’m afraid some came home with us. About 3 weeks after our trip, I got a rash on my neck, but it’s not very itchy. Haven’t seen any bugs at home, but am worried. Will try the tips in the article–any suggestions how to heat a bedroom to 120 degrees?
Hey Tyler! Besides calling an exterminator (since you cannot afford it), I would recommend washing all your bedding, clothes and other linen that may have come into contact with bed bugs and if you still have a problem, get your things steam cleaned. The heat will kill them and its great for treating the mattress, especially since you can do it yourself. Good luck!
People don't often consider bed bugs until they've left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don't spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
