Everything you need to know about bedbugs Bedbugs are small wingless insects that feed exclusively on the blood of warm-blooded animals. They need to feed regularly to reproduce, lay eggs, and survive. Two species eat human blood, usually feeding during the night. In this article, we explain the typical signs of bedbugs in the home and how to remove them. Read now


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.


Just recently had my first experience w/ bedbug bites in Nicaragua. Hundred plus bites in one night and over a period of three days they became so inflamed, there were tiny blisters on each bite. These suckers snacked on me like I was an all you can eat buffet. I itched 4 days straight and finally went to a pharmacy there, which prescribed me acne creme. Worked, I guess, at least psychologically. But the bites kept festering more and more.
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.

Infested mattresses and box springs can be discarded or wrapped in plastic to trap the bedbugs. Washing bedding and clothes in hot water and drying with high heat can kill bedbugs and their larvae. Cleaning and vacuuming furniture and floors can also help get rid of bedbugs. Shake out suitcases after traveling. Only use an insecticide in cracks on floors or furniture in areas that do not come into contact with skin. An exterminator can help if you're unable to rid the home of bedbugs.


To avoid light, bedbugs hide in the seams of mattresses and crevices of bed frames, walls, and furniture during the day.5,7 They are attracted to human hosts by warmth and carbon dioxide; these hosts generally sleep within 3 to 7 feet (1 to 2 meters) of the bedbugs’ hiding places.8,9 Feeding usually takes place just before dawn.10 Bedbug saliva contains several anesthetic, vasodilatory, anticoagulant, and proteolytic compounds that allow the insects to feed undetected for five to 10 minutes. Three of these compounds have been identified as instigators of the subsequent hypersensitivity reactions that may be noticed when the host awakens.11–14


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.

The symptoms of a bedbug bite are usually mild when present, and often individuals will not experience any symptoms at all. Bedbug bites can occur on any exposed part of the body, with the face, neck, arms, and hands being areas commonly affected. The signs and symptoms can appear from minutes to days after the initial bite. Affected individuals will usually complain of localized itching and reddish-colored skin lesions, which may look like a flat welt or a raised bump. Sometimes, the lesions can be found in clusters or in a linear pattern. Typically, these skin lesions will go away after one to two weeks.


Barriers: You can purchase bedbug-proof encasement covers for mattresses, box springs, and pillows. Also get bedbug interceptors to place under each leg of the bed or furniture items. These also allow you to see if there are any remaining bedbugs as they get trapped in the double rings of the interceptor disks. Ensure the bed is at least 6 inches from the wall and the bedding doesn't touch the floor.
My fiance and I have been dealing with bed bugs for 3 years. In the beginning I was the one being bitten. Just recently my fiance has been covered in bites. His lip is swollen this morning. We don’t know what to do anymore. This entire process is expensive and hard for us to afford. we’ve been treated by 3 exterminators. None have worked. I’m very upset because all of our belongings are damaged because of this! The Land Lord keeps bring exterminators and nothing’s working. we follow all the directions. I’ve checked my cat he seems to be fine, but I don’t know anymore. we’re miserable. I think we are stuck for life.

Items that cannot be placed in a washer or dryer can sometimes be de-infested by wrapping them in plastic and placing them outdoors in a hot, sunny location for at least a day (for example, on pavement or in a closed vehicle parked in the sun). Packing items loosely in garbage bags and elevating objects off the ground helps the heat permeate further, and will make it harder for bugs to find a cool place to hide. Monitoring with a thermometer is prudent to ensure that a temperature of at least 120°F is achieved wherever the bugs may be. 
It was stated in 2012 that no truly effective insecticides were available.[6] Insecticides that have historically been found effective include pyrethroids, dichlorvos, and malathion.[4] Resistance to pesticides has increased significantly over time, and harm to health from their use is of concern.[3] The carbamate insecticide propoxur is highly toxic to bed bugs, but it has potential toxicity to children exposed to it, and the US Environmental Protection Agency has been reluctant to approve it for indoor use.[33] Boric acid, occasionally applied as a safe indoor insecticide, is not effective against bed bugs[34] because they do not groom.[35]
Since DDT was banned there has been an escaltion of bugs. Malaria is killing millions and now bed bugs are taking over. I am waiting for a exterminaor right now. Something is biting me and I cannot find out what it is. I know Benadryl itch stopping cream has been my salvation. I have order a few things from an online shopping network and wonder if we are getting these bugs from other countrys. I am stopping all shopping online. The only way I feel like something is on me is to take a shower. Where is the CDC on this problem.
The exact causes of this resurgence remain unclear; it is variously ascribed to greater foreign travel, increased immigration from the developing world to the developed world, more frequent exchange of second-hand furnishings among homes, a greater focus on control of other pests, resulting in neglect of bed bug countermeasures, and increasing resistance to pesticides.[4][38] Declines in household cockroach populations that have resulted from the use of insecticides effective against this major bed bug predator have aided the bed bugs' resurgence, as have bans on DDT and other potent pesticides.[39][medical citation needed]
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!
General housecleaning measures, (e.g. vacuuming floors and surfaces), seldom reach where bed bugs hide. For this reason, repetitive vacuuming by occupants may not be worth the effort, especially compared to other important preparatory activities. Targeted vacuuming of bed bugs and infested harborages, however, can help remove some of the bugs before other treatment measures are undertaken. Bed bugs and especially the eggs can be difficult to dislodge. Optimum results will be achieved by moving and scraping the end of the suction wand along infested areas such as seams and fabric folds of beds and sofas, and the perimeter edge of wall-to-wall carpet. Bed bugs can survive the high speed trip down a vacuum, so it’s important to carefully dispose of the vacuum contents in a sealed trash bag afterwards. 
Bedbugs reproduce by a gruesome strategy appropriately named "traumatic insemination," in which the male stabs the female's abdomen and injects sperm into the wound. During their life cycle, females can lay more than 200 eggs, which hatch and go through five immature "nymph" stages before reaching their adult form, molting after each phase. [Infographic: Bedbugs: The Life of a Mini-Monster]
During the day, bedbugs tend to hide away in furniture, floors, beds, and in wood or paper trash. They typically feed on human or animal blood at night, and most bites occur just before dawn. After taking their meal, which can last as little as three minutes, they drop off the host and crawl to a hiding place. Bedbugs can live for up to 10 months and can go without feeding for weeks.

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?
Hi, I’m a little late to the talk but this is honestly very strange to me, i had bed bugs about a year ago and fully got rid of them, as of yesterday, 9/10, i woke up to bites on my right hand, palm and fingers not on the top of my hand, and on my right foot, in between my toes and the soles of my foot. i thought it may be bed bugs because of having 3 days so maybe one of them jumped on my bed and brought one along, but i decided to sleep one more night, i now got bit on me left hand and feet the same as my other bites, only on my toes soles palms and fingers, they’re red bumps that itch and whenever they’re pressed along something they hurt, if they are bed bugs why aren’t they like how i had them last time where i got bit everywhere there wasn’t hair, now I’m only getting bit in those spots, hopefully my info helps! Thanks!
Your replies to these questions are great! I have a question for you. I’ve recently returned home after spending a week in a hotel and the day after I returned I noticed 4 red dots which could be bites on my waist line. They don’t itch or hurt but I’ve never had anything like this before. I can send you a picture if you tell me how. I’m worried that they may be bed bug bites.
Now we are shut ins lol and dont allow guests to our home lol..We moved 1 hour away from town and have property now and 1 hour min away from most people we know..We go and visit them..When we return home from shopping/visits etc,we go into the 1st room and change,put our clothing in the laundry machine and check for bugs then put clean home clothing on !!!
Hey Randy! Based on your description of the situation, it does sound like bed bugs. Since you have had the similar experience for 5 years, I highly recommend getting someone to take a look at your bed for bed bugs. Something that you can try in the meantime is a close inspection of your linen. If you find any tiny blood marks on the sheets, that’s a tell tale sign of the presence of bed bugs. If you like you can send me a picture and I can take a closer look
According to textile experts (Drycleaning & Laundry Institute, Laurel, MD), most garments designated as ‘dry-clean only’ (e.g., cotton, wool, silk, linen, rayon, nylon) will not be harmed provided they are dry before being placed in a clothes dryer at a moderate temperature setting. Dry cleaning procedures also kill bed bugs, but there is a risk of infesting the establishment when buggy items are tagged and sorted. 
My daughter stayed at a friends for 2 nights…. And brought home bedbugs!! She has bites from the top of her head to her feet. The itching must be horrific. Poor child. After 2 days of not being able to stop the itching, as a last resort (on a Sun at 11pm) I told her to use a bathroom spray cleaner that had bleach in it. She only put it on her legs, but the itching stopped there, just not on arms, stomach or in her head. Don’t recommend bleach but she was able to get a couple hours of sleep. I will try several things to try to help her that I have read from previous comments. Thanks everyone….
I am now living in Kuwait far from my family, I was helpless and don’t know what to do, i was chatting w/ my mom and told her about my problem regarding the red spot comes out on my the under arm, i was crying for help coz i though i am sick.. my mother was so worried about me, until i decided search on internet related to my problem that doing facebook… i found this site then now i know it’s bed bug i think i took it from my friend room when i was slept there and I’m not dying as what i thought.. But my problem is i can’t wear backless dress, short pants because of the scar … anyone can help me how to remover this scar? it’s too disaster.

Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective.[3][6] An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them.[6] This may include a domestic clothes drier for fabric or a commercial steamer. Bed bugs and their eggs will die on contact when exposed to surface temperatures above 180 degrees and a steamer can reach well above 230 degrees.[31][15] A study found 100% mortality rates for bed bugs exposed to temperatures greater than 50 °C (122 °F) for more than 2 minutes. The study recommended maintaining temperatures of above 48 °C for more than 20 min to effectively kill all life stages of bed bugs, and because in practice treatment times of 6 to 8 hours are used to account for cracks and indoor clutter.[32] This method is expensive and has caused fires.[6][15] Starving them is not effective as they can survive without eating for 100 to 300 days, depending on temperature.[6] One expert recommends not trying to get rid of bed bugs exclusively on one's own.[29]
Its important to note that bed bugs can easily be transferred from other locations (such as hotels, friends, etc.) into your bedroom, something your definitely want to avoid! Its important to always check your skin, clothing and bags for any signs of bed bugs (and their bites) before entering your bedroom after sleeping away from the home. If you have been bitten a couple times, there is usually no urgent need for medical care. In fact, there are a number of effective home remedies that you can use to treat these insect bites. However, sometimes medical assistance is required. When is this the case and how can you identify when professional help is needed?

Hello, i was worried that we had bed bugs in our room and i hired an exterminator to come in and have a look. He said there was no evidence of bedbugs. And also because the bites were really only on the torso. Regardless, a few months later we had the opportunity to change the entire bedroom set and cleaned all the sheets on sanitize cycle – the bites all went away. Now, however, about 6 months later they seem to be coming back. Does this sound like a bed bug issue to you? If so, now what should we do? I cant but another bedroom set.
Some patients develop blisters filled with blood or bloody fluid, especially on the arms and legs. These blood blisters are extremely rare and can burst, causing bleeding or oozing of the bloody fluid. Healthcare providers are not sure if the cause of these blisters is related to the bug or the human but have found groups of patients that were all bitten by bugs on the same train exhibiting this sign.

They also have the ability to travel beyond the bedroom, so all adjoining rooms should be checked for infestation. Any area that offers a layer of protection, e.g. dark, isolated areas, should be checked. They do leave excrement droppings behind, so even if they are not seen, you can often see where they have been. The best method to find them is to check only at night, and with a red light.
Thank you so much for all the information. I just found a bed bug in my room at 5:00 AM in the morning. I have been getting these red itchy rashes for more than 2weeks . It’s extremely annoying and in spite of looking every where , I couldn’t find anything. These Biggs are so difficult to find. Now after reading this I feel they are even more difficult to eradicate.
Dusts last longer than aerosols, but the crack and crevice tips on the Phantom and Bedlam areosols enable you to get into the smallest cracks. It is a good idea to use a combination of sprays and dusts. Temprid SC may be used on the tufts and seams of mattresses. It works well as a residual insecticide sprayed in other recommended treatment areas such as night stands, chests, dressers, couches and chairs.
Vigilant travelers may also want to elevate suitcases off the floor on a stand, tabletop or other hard surface rather than storing them on the floor or another bed. Hyper-vigilant travelers may further opt to keep belongings in sealed plastic pouches and their suitcase in a zippered tote — however each traveler must decide how cautious they wish to be. 
As for traps, these capture methods may not be full-proof for all bedbug species. Researchers have found that while both the common and tropical bedbug species have hairy feet, C. hemipterushas denser foot hairs, making this tropical insect an expert climber on slick surfaces. In the study, detailed on March 15, 2017, in the Journal of Economic Entomology, the researchers found that adult tropical bedbugs were much better at escaping traditional pitfall traps, which held onto most of the common bedbugs in the study.

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.


No money whatsoever to do anything about it. I’m out of work and can’t even pay my rent. If we mention the infestation to the landlord he’ll toss us out because he’s in the process of selling the building. I’m going to try and go to an urgent care place to see if I can at least get something to stop the itching. This is driving me crazy with all the itching.
Just came back from a hotel stay, have one VERY itchy bite on my wrist. I don’t know for sure that it is a bed bug bite butI haven’t unpacked my bags yet, so hopefully everything is safe. Right now I have an aloe and lidocaine gel over the bite, but when I get home I may try soaking it in tea bath. the tannin in black tea can also help with itching and swelling.

Likewise, if I get bitten by a bed bug, I usually get a rather bad rash which is extremely sensitive to touch while they are hardly visible on my husband. If your bites become very itchy, you need to resist the urge to scratch the affected area as this can make the problem worse and cause further inflammation, infection or even bleeding. According to the Center for Disease Control, bed bug bites can even cause insomnia due to the fear of being bitten. This can result in a lack of energy and dramatically increased anxiety levels.


The treatment of bedbug bites depends on the symptoms and their severity. The bites should heal and disappear in one to two weeks whether you treat them or not. The goal is to prevent scratching the itchy rash, which can lead to a skin infection. You can use over-the-counter (OTC) anti-itch creams such as calamine lotion or those containing diphenhydramine or cortisone. Be sure to read the product label and don't use these creams around the eyes, anus, or genitals.
Bedbug bites usually do not require any treatment. If you develop itching of the skin around the site of the bite, you can use an over-the-counter antihistamine pill or cream such as diphenhydramine (Benadryl). Some individuals may also experience relief from the itching by applying a hot washcloth directly to the affected area. Try to avoid scratching the skin, as this can cause skin breakdown and a subsequent secondary bacterial skin infection.
I need some really serious advice. I’m presently staying in a shelter because of abusive situation. It’s only been two days but I am COVERED in bed bug bites. The shelter refuses to move me to another bed because of limited space they said. I have taken oral and topical medications. The thing is it keeps getting worse and worse because every night I have to sleep in the same bed.
We suggest if you are wanting to use any type of pesticide that you should hire a professional. Bed bugs often hide in places where pesticides can’t reach and pesticides can be very harmful if not used properly. If you are still wanting to treat bed bugs yourself we suggest using food or animal grade Diatomaceous Earth instead. Diatomaceous Earth is non-toxic and will dry out the bed bugs. Also here is a link to our 8-step approach to getting rid of the bed bugs. Please let us know if you have any other questions.
The common bed bug (C. lectularius) is the species best adapted to human environments. It is found in temperate climates throughout the world. Other species include Cimex hemipterus, found in tropical regions, which also infests poultry and bats, and Leptocimex boueti, found in the tropics of West Africa and South America, which infests bats and humans. Cimex pilosellus and Cimex pipistrella primarily infest bats, while Haematosiphon inodora, a species of North America, primarily infests poultry.[42]
Hi there! Honestly, if you have checked properly (like really well) and you don’t see any signs of bed bugs, it might be another insect. Unfortunately, there are so many little insects that could be biting you (such as fleas, etc.) but maybe start with giving all your laundry a good hot wash. Once that is done, see if you continue getting the bites and then we can investigate. Good luck, if you appreciated my help, please share my blog with your friends and family.
NEVER PUT ALCOHOL ON BEE STINGS OR WASP STINGS OR ANYTHING WITH A STINGER..it will force the venom into your blood stream and increase the danger, always use like Meat Tenderizer salt, toothpaste, and anything that draws out the venom from the skin. Use lemon juice, Aloe Plant, NEVER EXPERIMENT WITH TREATMENTS OF ANY KIND. i hope this helped. CHECK OUT YOUR LOCAL WHOLE FOODS STORES AND HERBAL STORES FOR HELP. BUY A BOOK ON HOME REMEDIES FOR INSECTS, GO TO YOUR LOCAL LIBRARY AND CHECK OUT BOOKS FOR HOME REMEDIES THAT ARE SAFE.
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 ?
I spent the night at my boyfriends house 5 nights in a row, knowing that his family owns a couch infested with bed bugs. I find it weird that I’m the only one, out of 7 family members, that gets bit by the bed bugs! Its crazy! I get bit during the day when I sit for a few mins, or even sleep on the bed at night, but it still baffles me that I’m the only one who is suffering from the itch of the bites. My son who I share the bed with does not get bit at all, which is great, but I’m curious, “why only Me?”
Help!! I have had a long and exhausting experience with these nasty bugs. My mother in law had stayed at my house for a few nights and a few weeks later after returning home she discovered she had a severe infestation of bed bugs.. so of course I took precautions at my home thinking she gave them to me. I threw my mattress away then taped off my entire bed with very sticky tape. No signs or bites at all . Then a few weeks later my son started to sleep in his bed again and sure enough he woke up with 3 bites in the shape of a triangle that were swollen and itchy. I searched his bed and found a casing shell and 3 blood stains under his box spring .I called a exterminator he came out and said we had a mild infestation and there was no signs in my bed but he found one live bug in my son’s bed. He treated the bedrooms and living room. Then my son and i were getting these little bumps on our body that looked nothing like the triangle bites and didn’t itch so the exterminator came again and treated but found no evidence of bed bugs and this cycle happened four times! So he has treated my apartment 4 times and found no signs of bed bugs and even had a dog come out to sniff around .. this was all over the course of about 5 months . The exterminator insists that we do not have bed bugs anymore but my son is still getting these bumps on him, some are reds dots and some are skin colored but no complaining of itching . I’m very overwhelmed and exhausted and havery no idea what to think. I think the tape on my bed prevented them from getting back into my bed after I threw my mattress out but again the exterminator said tape does not work. Are they hiding somewhere else like in the walls to where the exterminator think the problem is gone ?
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.
