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]
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]

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). 

These nocturnal creatures can hide in beds, floors, furniture, wood, and paper trash during the day. We humans usually become their dinner during the night, with peak biting activity just before dawn.They can obtain their meal in as little as three minutes, after which they are engorged and drop off the host, then crawl into a hiding place to digest their meal. Bedbugs can live for 10 months, and can go weeks without feeding.


Bedbugs are small oval-shaped non-flying insects that belong to the insect family Cimicidae, which includes three species that bite people. Adult bedbugs reach 5 mm-7 mm in length, while nymphs (juveniles) are as small as 1.5 mm. Bedbugs have flat bodies and may sometimes be mistaken for ticks or small cockroaches. Bedbugs feed by sucking blood from humans or animals. Cimex lectularius is the scientific name for bedbugs.

Nightstands and dressers may need to be emptied and examined inside and out, and tipped over to inspect the woodwork underneath. Oftentimes the bugs will be hiding in cracks, corners, and recesses. Other common bed bug hiding places include: along and under the edge of wall-to-wall carpeting, especially behind beds and sofas; cracks in wood molding; ceiling-wall junctures; behind wall-mounted pictures, mirrors, outlets and switch plates; under loose wallpaper; clothing and clutter within closets; and inside clocks, phones, televisions and smoke detectors.
"We originally thought the bedbugs might prefer red because blood is red and that's what they feed on," study co-author Corraine McNeill, an assistant professor of biology at Union College in Lincoln, Nebraska, said in a statement. "However, after doing the study, the main reason we think they preferred red colors is because bedbugs themselves appear red, so they go to these harborages because they want to be with other bedbugs, as they are known to exist in aggregations."

Bed bug eradication is challenging and it’s prudent to hire a professional when resources allow. However treatment can be expensive, often costing hundreds or thousands of dollars. Those who cannot afford this often must cope with the problem themselves. A useful step that anyone can take to combat bed bugs is to install bed encasements. Covering the mattress and box spring can help eliminate a substantial portion of the bed bug population -- especially if discovered early while most of the bugs are still confined to the bed area. Extra care should be taken when installing budget encasements since these can tear easily, especially on metal bed frames. Ideally both the mattress and box spring should be encased. If only one encasement is possible it’s often best to cover the box spring which is harder to subsequently inspect.


We helped a girl who we ran into who was being beaten by her B/F. She and her daughter stayed one night, and we got them to a safe place. Now we have bed bugs. I threw away our bed. (Our guest had used one of our blankets.) Thank God my landlord is going to get an exterminator! It’s at least $300 for them to come in. And yes, the itch is unbearable.
just got back from two weekends of traveling to two diff locations. noticed a slight rash yesterday on the side of my ribs and a couple smaller itchy spots on one side of my stomach, etc. i don’t think it was from the first weekend of travelling as my bed companion didn’t get anything. the second weekend was at a college campus, but i had wiped the bed down before putting sheets and a sleeping bag over it. got back home sunday and noticed the itch yesterday (tuesday). so now i’m freaking out and assuming the worst scenarios. i’ve washed and dried all my clothes (though i did leave my suitcase out for two days before i even realized the itch), my sheets, and used a handheld steamer on my mattress, clorox / lysol the edge of my bed and the wooden frame, vacuumed all open areas on my wooden floor, etc. not sure if i should go to urgent care or what, but i’ve so far used hydrocortisone (previously already prescribed). can you please help or can i send you photos since you’re more familiar with this? never happened to be at home before all 20 something years so now i’m terrified i brought something back with me!
My bites from two weeks ago are still rough. I have used the window cleaner, cortisone and then for the open areas , antibiotic ointment. I slept in my bed last night with no problem. I will spray again and again and again in the event of new generations. They don’t sell Phantom in my area. That is supposed to kill 95% of the eggs. Wish I could find some. These little bastards are something else. Good Luck to all.

My husband and I recently stayed at a Scottish Inn, off I-75 in Florida, on our way back from NJ. We needed a room on the first floor. The only thing they had was a $32.00 room + tax. Since we were tired from driving, we took it. During the night, I woke up and I felt like something had bitten me. When we got up to get ready to leave, I noticed both my arms, left leg, one on my face, left ear and one bite on my neck had been bitten. I immediately took a hot bath, but I still can’t stop itching. I’ve never had bed bug bites before so I visited this site. I definitely will be trying the baking soda and water mix. My husband has two bites on his arm, but they’re not as bad as mine. He thinks he received them at the prior motel we stayed at.

When I discovered bed bugs, at first I thought it was just mosquitoes or something. It wasn’t they his exceptionally well. I cleared any clutter I had, especially near the bed. How to Treat Bed Bug Bites, or bugs in general is you need to first inspect the bed. The black dots are a sign where they dwell. You need to be careful not to alarm them or they’ll just move to another location that’s harder to find.

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.
CrossFire Bed Bug Concentrate has two different active ingredients for dual modes of action (both a quick kill and residual activity). Mix 3 oz of CrossFire Insecticide with one gallon of water or 0.75 oz per quart (Remember to use what you mix-within 24 hours.) Adjust the spray pattern to a mist by turning the nozzle. A low fine mist is best for most spraying, but you may need to use a stream to get into some cracks and crevices. If you can't get into the cracks and crevices use one of the aerosols described below with it's crack and crevice tips to reach into these areas.

A common concern with bed bugs is whether or not they transmit diseases. Although bed bugs can harbor various pathogens, transmission to humans has not been proven and is considered unlikely. Their medical significance is most commonly attributed to itching and inflammation from their bites. Antihistamines and corticosteroids may be prescribed to reduce allergic reactions, and antiseptic or antibiotic ointments to prevent infection. Though not known to carry diseases, bed bugs can substantially reduce quality of life by causing discomfort, sleeplessness, anxiety, and embarrassment. According to some health experts, the added stress from living with bed bugs can have a significant impact on the emotional health and well-being of certain individuals. 


Hi, I’ve been in my apartment for over 8 years. We just had new neighbors move into our building. Now me and my children are getting bit at night by something. So, this morning, I was sitting on the couch in my bedroom and a bug crawled up my pants’ leg. I captured it in a plastic bag. I believe it’s a bed bug but is there a way to submit a picture to you, so you can take a look? Thank you!

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.
