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
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.

Bed bugs occur around the world.[36] Before the 1950s about 30% of houses in the United States had bedbugs.[2] Rates of infestations in developed countries, while decreasing from the 1930s to the 1980s, have increased dramatically since the 1980s.[3][4][36] Before the 1980s they were common in the developing world but rare in the developed world.[4] 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.[37]
Avoidance is the best means of preventing bedbug infestation.8 While traveling, sleeping quarters and bedding should be closely inspected for signs of bedbugs. Suitcases should be placed on metal racks away from walls and furniture. Frequent travelers might consider obtaining a portable heating unit for luggage and clothing (e.g., Packtite) as an additional precaution. Items at yard sales and secondhand stores should also be carefully examined before purchase.8  All potentially infested items should be sorted and sealed in plastic bags and removed only when ready to be disinfested (see Table 36 for instructions regarding effective care of infested items). Wearing long-sleeved nightclothes can minimize exposed skin, and although insect repellants have not been shown to be reliably effective, oil of lemon eucalyptus or diethyltoluamide (DEET) might help deter bites.44,45
Treatment is symptomatic.[2] Eliminating bed bugs from the home is often difficult.[2] Part of this is because bed bugs can live for a year between feeding.[2] Repeated treatments of a home may be required.[2] 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.[2]
These blood suckers lock on to the carbon dioxide (CO2) release when sleeping. Once they have you, they head toward a warm part of your body and begin to bite. Two tubes are inserted into your body; one is used to inject a mixture of anticoagulant and anesthetic while the other is used to suck up your blood. You never notice the bites until you wake up and realize you were the main course!
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?
Bed bugs are a traveler's nightmare. They can be picked up in hotel rooms, leaving red itchy bumps and possibly rashes to ruin your vacation. Or even worse: If you accidentally bring them back with you, they could infect your whole house. To prevent a plague of bed bugs, here are some tips of what to check while you're on the road and how to determine the symptoms of bed bug bites.

The bites do not usually require medical treatment. Secondary bacterial infection of the skin may develop in areas that become irritated due to prolonged scratching. Topical antibiotic creams or ointments may relieve symptoms of a secondary infection. Antiseptic lotions may also be beneficial. If you've had an allergic reaction to the bedbug bites, your doctor may recommend oral antihistamine medications or corticosteroids.


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!!
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
These bugs are extremely sensitive to heat in every stage of their life. Thermal death point of a common bed bug is just 111°F to 113°F. Many times even temperatures that are lower than this, 97°F to 99° F can kill multitudes. If the temperature is raised to 140° F for about an hour or to 120°F for several hours most infestations will be eradicated.
Hi i am grying to figure out what these bumps are on the back of my neck by my hair line.. i have one near the back of one of my wars but srillat my hair line…then i also have one a that is a few inches away from it that is as well at my hair line but it is towards the back of my neck and i have one that is about an inch away from that one near my hair line. They do not itch and they just apeared tonight while i was working….i am constantly spraying my bed because of bed bugs in the past. Do these sound like bed bug bights sincr it really isnt in a cluster and they arnt in a straight line???? Please help me…
Encasing mattresses is one of many good parts of a solution, but it doesn't get rid of the infestation. There are going to be other bugs away from the mattress, hiding nearby. What mattress covers are good at is entombing the sometimes large number of bed bugs that can live on a mattress. And because the covers tend to be uniform in color and don't have a lot of seams that the bugs can hide in, it's easier to see the insects.
you have to get the heat treatment on your house & wash & dry EVERYTHING you own in a very hot dryer some there maybe some help to pay for it if you own your home w a no interest loan or if you rent you better tell your landlord he needs to treat his whole property & i bet he wont be happy its very expensive my moms apt bldg gets a dog checking every unit & its $850 for her tiny one bedroom..i just read a house can be $1500 to $2000 theres a hair treatment too its a very hot comb that costs about $150 a person..you cant be going to peoples homes anywhere you go youre spreading the joy
Our place is pretty cluttered so I was freaking out. Luckily we have hardwood floors and not carpet. We tried different things. It gets really hot here, so I loaded up any nearby sheets, pillows, comforters, clothes, etc into trash bags and tied them off so nothing could get out. I put those in the car so the sun could beat heat into them all day. Never thought I’d be so thankful for Texas summers… Still got bites. We bought a mattress cover. Still got bites. We thought, okay, maybe they’re coming from the wall socket from a neighbors or something. We couldn’t close it so we kept the bed away from furniture and walls and put sticky traps on the legs. Caught NO bed bugs but STILL GOT BITES. I was losing my mind.

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.
I’m suffering a similar problem. I had a friend who stayed with me on and off for a few months. She just didn’t tell me she had bed bugs right away. I had three kids and one on he way at the time. I bombed everything, threw out lots of things, and washed everything. Its now been a year and they’re back. Only now i have three kids and I have recently become the only income. Im barely holding rent and i don’t know what to do. I’m about ready to burn everything i own. I just can’t take it. I work 40 hrs., go to school, and have a child starting school in a week. Urgggg!!!!!!
Bedbugs are a species of insect known as cimex lectularius (literallycimex is Latin for bug and lactularius is Latin for bed). There is a second common species of bedbugs known as cimex hemiptera. These are known as the tropical bedbugs, staying within 30 degrees of the equator. There are published reports, many without supporting evidence, that each of the common bedbug species has chemically different saliva. Some researchers, however, have found no difference in the reactions caused by each species.

Bed bug bites typically appear in groups of three, called the "breakfast, lunch, and dinner" pattern. Each victim's reaction to bed bug bites is unique. Some may have a slight reddening of the skin. Others may have a more severe reaction, causing a raised, itchy rash. A raised rash may obscure the individual bites, making it challenging to identify. Sometimes, bites and lesions can throb and become very painful for days after the bugs bit you.

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.

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.
The first sign of a bed bug problem is obvious: the bed. After bed bugs feed on humans, they'll leave behind blood stains resembling small rust spots. These will usually be found near the corners and edges of the bed. Bed bugs also shed their skin, or molt, several times as they mature, so you may find their oval brown exoskeletons during your search.
