Bed Bugs FAQs
What are bed bugs?
Bed bugs (Cimex lectularius) are small, flat, parasitic insects that feed solely on the blood of people and animals while they sleep. Bed bugs are reddish-brown in color, wingless, range from 1mm to 7mm (roughly the size of Lincoln’s head on a penny), and can live several months without a blood meal.
Where are bed bugs found?
Bed bugs are found across the globe from North and South America, to Africa, Asia and Europe. Although the presence of bed bugs has traditionally been seen as a problem in developing countries, it has recently been spreading rapidly in parts of the United States, Canada, the United Kingdom, and other parts of Europe. Bed bugs have been found in five-star hotels and resorts and their presence is not determined by the cleanliness of the living conditions where they are found.
Bed bug infestations usually occur around or near the areas where people sleep. These areas include apartments, shelters, rooming houses, hotels, cruise ships, buses, trains, and dorm rooms. They hide during the day in places such as seams of mattresses, box springs, bed frames, headboards, dresser tables, inside cracks or crevices, behind wallpaper, or any other clutter or objects around a bed. Bed bugs have been shown to be able to travel over 100 feet in a night but tend to live within 8 feet of where people sleep.
Do bed bugs spread disease?
Bed bugs are not known to spread disease. Bed bugs can be an annoyance because their presence may cause itching and loss of sleep. Sometimes the itching can lead to excessive scratching that can sometimes increase the chance of a secondary skin infection.
What health risks do bed bugs pose?
A bed bug bite affects each person differently. Bite responses can range from an absence of any physical signs of the bite, to a small bite mark, to a serious allergic reaction. Bed bugs are not considered to be dangerous; however, an allergic reaction to several bites may need medical attention.
What are the signs and symptoms of a bed bug infestation?
One of the easiest ways to identify a bed bug infestation is by the tell-tale bite marks on the face, neck, arms, hands, or any other body parts while sleeping. However, these bite marks may take as long as 14 days to develop in some people so it is important to look for other clues when determining if bed bugs have infested an area. These signs include:
- the bed bugs’ exoskeletons after molting,
- bed bugs in the fold of mattresses and sheets,
- rusty–colored blood spots due to their blood-filled fecal material that they excrete on the mattress or nearby furniture, and
- a sweet musty odor.
How do I know if I’ve been bitten by a bed bug?
It is hard to tell if you’ve been bitten by a bed bug unless you find bed bugs or signs of infestation. When bed bugs bite, they inject an anesthetic and an anticoagulant that prevents a person from realizing they are being bitten. Most people do not realize they have been bitten until bite marks appear anywhere from one to several days after the initial bite. The bite marks are similar to that of a mosquito or a flea — a slightly swollen and red area that may itch and be irritating. The bite marks may be random or appear in a straight line. Other symptoms of bed bug bites include insomnia, anxiety, and skin problems that arise from profuse scratching of the bites.
Because bed bug bites affect everyone differently, some people may have no reaction and will not develop bite marks or any other visible signs of being bitten. Other people may be allergic to the bed bugs and can react adversely to the bites. These allergic symptoms can include enlarged bite marks, painful swellings at the bite site, and, on rare occasions, anaphylaxis.
How did I get bed bugs?
Bed bugs are experts at hiding. Their slim flat bodies allow them to fit into the smallest of spaces and stay there for long periods of time, even without a blood meal. Bed bugs are usually transported from place to place as people travel. The bed bugs travel in the seams and folds of luggage, overnight bags, folded clothes, bedding, furniture, and anywhere else where they can hide. Most people do not realize they are transporting stow-away bed bugs as they travel from location to location, infecting areas as they travel.
Who is at risk for getting bed bugs?
Everyone is at risk for getting bed bugs when visiting an infected area. However, anyone who travels frequently and shares living and sleeping quarters where other people have previously slept has a higher risk of being bitten and or spreading a bed bug infestation.
How are bed bugs treated and prevented?
Bed bug bites usually do not pose a serious medical threat. The best way to treat a bite is to avoid scratching the area and apply antiseptic creams or lotions and take an antihistamine. Bed bug infestations are commonly treated by insecticide spraying. If you suspect that you have an infestation, contact your landlord or professional pest control company that is experienced with treating bed bugs. The best way to prevent bed bugs is regular inspection for the signs of an infestation.

The first sign of bedbugs may be red, itchy bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites, unlike some other insects that leave bites here and there.
Bedbugs do not seem to spread disease to people. But itching from the bites can be so bad that some people will scratch enough to cause breaks in the skin that get infected easily. The bites can also cause an allergic reaction in some people. Read more about bedbug bites – symptoms, treatments and prevention.

Bedbugs Slideshow: An Informative Look at Bedbugs
DonвЂ™t Let the Bedbugs Bite
As if you needed something else to worry about, bedbugs, those pests from the old bedtime rhyme are making a comeback. More of a nuisance than a health hazard, theyвЂ™re showing up to suck blood from people in hotels, college dorms, and hospitals. Take an informative look at bedbugs: what they are, where they lurk, and how to spot them before they get you.
Know the Enemy
Bedbugs are small, flat, wingless insects with six legs that, like mosquitoes, feed on blood from animals or people. They range in color from almost white to brown, but they turn rusty red after feeding. The common bedbug doesn’t grow much longer than 0.2 inches (0.5 centimeters) and can be seen by the naked eye to the astute observer.В Bedbugs get their name because they like to hide in bedding and mattresses.
Am I at Risk for Infestation?
Bedbugs are most often found in hotels, hostels, shelters, and apartment complexes where lots of people come and go. Because bedbugs hide in small crevices, they can hitch a ride into your home on luggage, pets, furniture, clothing, boxes, and other objects. Bedbugs are found worldwide, but are most common in developing countries. Once rare in North America, they may be on the rise due, in part, to increases in international travel.
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.
Signs and Symptoms of Bedbug Bites
Amazingly, these sneaky little bloodsuckers dine on you without waking you. You don’t feel their stealthy bite because they inject a numbing agent into your body, along with an anticoagulant to keep your blood flowing as they suck. The first sign of bedbugs may be itchy, red bites on the skin, usually on the arms or shoulders. Bedbugs tend to leave straight rows of bites.
Bedbug bites do not usually require treatment. If a secondary infection occurs (usually from scratching), apply a local antiseptic lotion or antibiotic cream or ointment. Creams with corticosteroids and oral antihistaminesare used for the primary, unbearable symptom of itch. In these more severe cases, you may need to see your doctor.
Do Bedbugs Transmit Diseases?
Bedbugs are more of a nuisance than a health hazard. In a recent study, researchers reviewed 53 recent studies on bedbugs and their health and medical effects. The results showed that although bedbugs have been blamed for the spread of up to 40 different human diseases, there is little evidence to suggest they are carriers of human disease.
Bedbug or Imposter?
Don’t assume your bites are bedbugs. Bites can be hard to identify, even for doctors. Rule out mosquitoes, fleas, mites, and biting gnats by conducting a visual inspection. It’s best to collect and identify bedbugs to confirm bites. Look for the bugs themselves or their bloodstains, especially along the seams of mattresses. Further, look for dark spots of insect waste where bedbugs might crawl into hiding places on furniture, walls, and floors.
Bite Back Against Bedbugs
Professional exterminators should get involved right off the batвЂ”tell your landlord, super, hospital administrator, hotel owner, or you call a professional right up front. The exterminator will locate the bed bugs (which may be found in more than one location) and exterminate as needed. YOU will have to do a lot of laundry.В

Information about bed bugs bites, pictures of what do bed bug bites look like, how to check if you have been bitten by bed bugs and advice on how to stop the itch.
Bed bugs are nocturnal insects that feed mostly at night when their hosts are asleep. In the day, they hide in cracks and crevices of walls, bed frames, bookshelves, basically anywhere that gives them easy access to humans, although they are fast moving insects that are able to travel great distances.
Bed bugs bite their hosts by using their sharp beak to pierce the skin and inject their saliva. Like mosquitoes, their saliva contains an anticoagulant (to prevent coagulation of the blood) as they suck and also acts as an anesthetic agent to prevent the victim from feeling the bite. Therefore, while sleeping, humans rarely feel any sensations of being bitten, but will only realize the day after.
Nymphs (young bed bugs) take about three minutes to feed, while a full-grown bug feeds for ten to fifteen minutes. After feeding, they then crawl back to the nearest crevice to digest.

So, my story starts in Halifax, Nova Scotia. I am currently attending university and have lived in residence for the last 3 years. I started developing this really bad rash the last few months (more than a few actually) and I thought it was heat rash because I would only get it when I sweated or got hot. However, I just checked the side of my mattress and low and behold, black dots everywhere. This has caused me such embarrassment because everywhere I would go leaving the house, I would have these hives looking rash all over my arms. I am finally moving out of residence and saying goodbye to these horrid blood suckers once and for all. I even tried allergy medicine with antihistamine because I thought it was an allergic reaction, which it is, but you cant really cure allergic reaction to bed bug bites with zyrtec, benedryl, or claritin.
thanks and I hope my story helped!
What Are The First Signs And Symptoms of Bed Bug Bites?
Often, the bites of bed bugs are mistaken or misdiagnosed for other common household insects since the bites can look almost identical to those caused by other parasitic blood feeding insects such as mosquitoes, fleas, ants and lice.
image credit: urbanentomology.tamu.edu
Nevertheless, bed bugs bites can be easily recognizable once you know what are the symptoms to look for.
The first tell tale symptoms of bed bug bites are the multiple small, flat or raise welts on the skin that will always appear in a linear three in a row or clustered pattern because of the bed bugs tendency to feed on the same location more than once. Experts usually describe the three in a row bite marks as breakfast, lunch and dinner. The welts can turn red, flare up and become itchy. Scratching the bitten areas may also cause the welts to blister, have an infection or leave scars.
The next tell tale sign that may indicate your bed is infested is that you will get bitten every night while you are sleeping and develop similar clustered pattern large itchy welts every morning.
Other possible signs of an infestation are tiny blood spots on bedding materials of dead bugs that are crushed during feeding or staining on the mattress from the waste of the bugs.

Bed Bugs Vs Fleas, Spiders and Mosquitoes Bites – What Are The Differences?
Even though bed bug bites cause itchiness and irritation to the skin similar to flea, spider and mosquito bites, there are a few differences.
The bites of bed bugs usually appear as small, red welts and tend to show up in groups or in a line formation on the hands, feet, neck and other exposed body parts during sleep. For most victims, the bites will cause intense itching for several days.
Since bed bugs feed at night, you may most likely notice that you have been bitten only after you have woken up in the morning. Sometimes, the bites may also tend to appear more rash-like rather than bite-like, which is why the symptoms of the bites can sometimes be mistaken for other types of skin rashes caused by laundry detergent, soap and other cleaning products.

Flea bites can look very similar to the bites from bed bugs since they also occur in groups and itch a lot but the bite marks of fleas are typically smaller and more pinkish in color. Common household flea bites also tend to occur mostly on the lower part of the body around the legs, ankles and behind the knees.
Most of the time, the only way of knowing whether you have being bitten by fleas is asking yourself if you have recently come into contact with any household pets like dogs and cats or wildlife animals such as raccoons, rabbits and rats that typically carry fleas that bite humans. Most of the time, children end up with flea bites playing with their dogs and cats. There are also cases of individuals being bitten by sand fleas which are found commonly around beaches, wetlands and swamps.

The characteristics of a spider bite is usually large, isolated swelling that show up immediately after the bite revealing that the skin may be pierced. Depending on the toxicity of the spider bite, one may feel the painful sting of the bite much like the sting from a bee and the pain can last for a few minutes to as long as a day or two.

When an individual is bitten by mosquitoes, the bites tend to flare up quickly as pale pinkish bumps with uneven swelling on the skin. Reactions may vary but most individuals will experience itching around the bite area for a few hours with the itch gradually disappearing after a day or two.

Again, for those who are still unsure about what insects bit you, entomologists and pest control experts receommends that the best way to identify whether one is bitten by bed bugs is to physically check for the signs of the bugs themselves. Look for the live bugs or other signs of recent activity like the outer exoskeleton casings where the bugs shed, droppings and newly formed dried blood stains on the bed sheets.
For the uninitiated, read this post on how to check for signs of bed bugs at home and in a hotel room.
Where Do the Bites Most Commonly Occur?
Any exposed areas of the bodies while one sleep are target spots for a bed bug to bite and suck on for blood. The face, neck, back, hands, arms and legs are the most common areas where bed bug bites occur.

How Long Does the Bite Rash Last?
Reaction to bed bug bites depends on the individual. Some people will not have any reaction at all while for others who are quite sensitive to bites, they may have localized allergic reactions and develop blisters or rashes that can be extremely itchy as they get bitten repeatedly.
Typically bed bug rashes will show up a few hours after the actual biting but there are some cases whereby the rash does not appear until a few days or even a week later since this is dependent on the allergy reaction to the person who is being bitten.
Generally, the rashes of bed bugs will last for two to three days and then slowly fade away. However the rashes can last much longer if the person is more allergic prone. Often it will require some medical intervention to finally clear up the skin rash completely.
Do Bed Bug Bites Transmit Disease?
Are the bites of bed bugs dangerous or contagious? Even though these tiny and bloodthirsty pests are really bothersome and considered a nuisance, their bites are fairly harmless and are not known to spread any diseases.
Nonetheless, on very rare occasions an allergic reaction to the bites has caused nausea, sickness and even shock. Some people may also be affected psychologically and not be able to fall asleep.
|A Reader’s Comment on The Effects of Bed Bug Bites|
I started with hundreds of bites on my body a year ago. I ended up in the ER because I had no idea what was wrong with me. I then went to 3 specialist, had biopsies and still no one knew what it was. I was able to move from that apartment in 3 months to a different complex. (because of the bed bug infestation that I had never experienced before. I am still getting bitten, severe itching, scars all over my legs, arms, neck and crease at top of my legs before entering private parts. No prescription has helped. I’ve had many. Calamine lotion helps with the itching but it’s messy and leaves a residue on your skin. I’ve had cortezone shots for the itching. did not help.
I have to wear clothing to help cover the marks to be able to work. My mattress and box springs have been encased in bed bed zippered bags since December, and then adding another cover over that this year. I cannot afford to trash my mattress. I did however trash my bedding and started over. My pillows are also protected with a zippered covering.
The itching is horrible and the same bite marks I’ve had for at least a year seem to be re-infecting. They get red and swollen. I also have several on my body that have started to go away or I mean you have to look really close to see. I started tanning and the heat helps and also starts tanning the scratched skin to blend with my normal skin.
This is HORRIBLE. I actually think just today I caught one on my bed and then looked on the computer and it does look like one of the species. I drowned it with 2 more I think I found. I heard they were sensitive to light so I sleep with the lights on. I’m not even sure anymore if all the itching is real. It could be psychosomatic. I always have a feeling something is crawling on me. It’s like when you see an ant on a picnic and can’t get that thought off your mind and start itching. The bite usually is invisible to the naked eye, but once you start itching, the area expands to the skin torn off.
How to Treat Bed Bug Bites?
For fast relief from the discomfort and itchness of the bites, you are advised to run it under lukewarm running water for approximately a minute and clean the affected area with an antibacterial soap, which will minimize the inflammation and irritation as well as take your mind off it.
For a stronger treatment for the skin rashes, severe itchiness or to prevent infections, you can apply local antiseptic lotion, antibiotic cream or oral antihistamine. Some of the recommended topical steroid creams for the treatment of the bites are hydro-cortisone – Cortaid Intensive Therapy , for example – that helps to stop the itch and resolve any rash quickly.
How to Avoid Getting Bitten Again?
First, try to confirm the presence of bed bugs even if you suspect that you have been bitten by the tiny blood feeders.
It is best to first visually inspect your bed and room for any telltale signs of the bugs. If the brown critters are found, one can contact a reputable pest control company for the extermination of bed bugs .
For homeowners who are looking for ways on how to prevent getting bitten, here are some useful steps one can take to protect yourselves:
- Clear away unwanted clutter and clean your room thoroughly. Vacuum carpets and seal any cracks in the wood floors.
- Wash all bedding and clothing in hot water for at least 20 minutes. Bed bugs are very sensitive to heat and will die at temperatures above 120В°F.
- Use a quality bed bug spray to kill off any visible bugs one can find especially around and behind the headboard, bed frame as well as upholstered furniture near the bed. Follow up the treatment with professional insect powders such as Diatomaceous Earth by applying it around the bed and carpet to defend the perimeters.
- If you are still worried, one can also use thick, double-sided tape to tape it around the bottom of the bed frame or use professional traps as a tool to detect and prevent bed bugs before they bite.
- Encase the mattresses with bed bug proof covers that are designed to contain fleas and bugs. Similarly, the pillows and bolster must be encase too to be effective in preventing bed bug bites. The covers will work both ways to prevent new infestations as well as trap existing bugs on the inside from getting out to feed.

Bed bug bites: What you need to know
If you buy something through a link on this page, we may earn a small commission. How this works.
Most people who are bitten by bed bugs experience symptoms that include irritation, sores, or itchiness. But how should bed bug bites be treated and can they be prevented?
There are several ways of reducing the chances of getting bites, while the treatment options include good hygiene and antihistamines.
This article explores bed bug bite treatment and prevention methods in detail.
Bed bugs are small parasitic insects that feed on human blood.
While they are a public health concern, bed bugs are not known to transmit disease through their bites.
Bed bugs use a small tube-like structure called a proboscis to pierce the skin and drink a person’s blood. The pests are most active when humans are asleep, during the night and early morning.
An estimated one in five Americans have personally dealt with a bed bug infestation or knows someone who has encountered the pests.
Bed bugs can bite anywhere on the body where there is skin. Typically, bites tend to occur on areas exposed during sleeping, such as:
Many people do not feel the bite itself or develop clear symptoms other than the dots where the bug bit and some minor, surrounding inflammation and irritation. Others are considered hypersensitive to bites and develop more severe symptoms.
In most cases symptoms occur more or less immediately after the bite, but they can develop or progress over the following days as well. Without further irritation, symptoms typically resolve after a week or so.
Almost all bed bug bites will produce some degree of discomfort, typically itchiness and inflammation. Other signs and symptoms of bed bug bites include:
- a burning painful sensation
- a raised itchy bump with a clear center
- a red itchy bump with a dark center and lighter swollen surrounding area
- small red bumps or welts in a zigzag pattern or a line
- small red bumps surrounded by blisters or hives
- papular eruptions or areas of skin with raised or flat patches that may be inflamed
- small spots of blood from bites often dried or stained onto sheets or bed clothing
- reddish or reddish-brown dried stains on fabrics due to bed bug droppings
- white or clear skins, shed by the nymphs as they mature
Individual characteristics of the bug’s bite and the person who is bitten also influence the resulting sore.
While fairly rare, some people have or develop severe reactions and symptoms from bed bug bites. Serious symptoms that require medical attention include:
- difficulty breathing
- feeling nauseous or flu-like
- swollen tongue
- irregular heartbeat
Living with bed bugs can cause additional health complications:
- Increased likelihood of infection: Due to the skin’s surface being compromised.
- Sleep deprivation: The idea of being fed on can be extremely stressful. Given that the bugs only feed at night, some people will avoid sleep or will only get fitful or restless sleep.
- Decreased wellbeing: A continual lack of sleep has been linked to feelings of depression, anxiety, general fatigue, and lowered immune function. The misconceptions surrounding bed bugs, especially the mistaken association with lack of cleanliness, can add to feelings of depression and low self-esteem.
There are relatively few treatments options when it comes to uncomplicated bed bug bites.
The first recommended line of treatment involves cleaning the wound, ideally with soap and water.
For itchy bites, the following may relieve minor symptoms:
- over-the-counter hydrocortisone, which can be purchased online.
- anti-itch creams
Most wounds heal on their own within a week, sometimes two.
If severe swelling, inflammation, or itchiness occurs or persists, a person should seek medical attention.
A dramatic immune response may be a sign of an allergic reaction. If this is the case, one of the following may need to be administered:
- an injectable corticosteroid
- epinephrine medication
If infection occurs, antibiotics may be prescribed.
Severe itchiness may result in further complications, such as infection or scarring. If severe itching is experienced, people may be prescribed corticosteroid creams and antihistamine pills or liquid.
One way to help prevent exposure and potential infestations by bed bugs is to be able to recognize bed bugs and distinguish them from other pests.
In a 2017 study, some 35 percent of polled American business travellers and 28 percent of leisure travellers were unable to tell a bed bug apart from other household pests.
Common characteristics of nymphs (young bed bugs) include:
- being less than than 5 mm in length
- whitish-yellow and or clear-colored
- invisible without a microscope or magnifying glass
The nymphs are easier to see if they have just feed when the blood fills their abdomen, giving it a reddish brown color.
Adult bed bugs are typically far easier to spot than nymphs. Identifiable characteristics of most adult bed bugs include:
- an oval-shaped body
- apple seed in size
- a body that is fairly flat unless recently fed and inflated
- reddish-brown to light-brown or tan color of shell, depending on how recently it fed
- a length of 5-7 millimeters (mm)
- three segments, an antenna with four parts, short yellow hairs, and unusable wings
- a musty or stale-sweet scent released by glands on the underbelly
Controlling bed bugs needs the identification and complete removal or destruction of the pest’s eggs.
On average, one female can produce at least 345 eggs over her lifetime. Egg-laying females often increase the volume and frequency of feeding to support their brood.
Common characteristics and signs of bed bug eggs include:
- they are often laid in the same places where the female choses to rest
- they resemble tiny barrel-shaped, pearl-colored specks, no bigger than the head of a pin
- they develop a noticeable eye spot after a few days
The key to preventing bed bug bites is to stop the insects entering, feeding, and breeding in human environments.
In the daytime, bed bugs often seek refuge in the cracks and crevices of furniture, flooring, walls, and mattresses.
The seams and folds of upholstered furniture can also offer an ideal hiding place. Bed bugs have been known to persist in vacuum canisters or units.
The insects tend to pick hiding spots near human sleeping quarters, including bedrooms. Bed bugs found in other rooms are usually a sign of a severe infestation.
Areas where bed bug infestations commonly occur include:
- apartment or condominium buildings
- large office spaces
- vacation rentals
- cruise ships
- nursing homes
- college dormitories or housing units
- public transportation, including airplanes
- shopping malls
- furniture or second hand stores
- urban areas
- rented homes
Items commonly responsible for spreading bed bugs include:
- used or secondhand furniture
- new furniture or textiles exposed to bed bugs during transit
- items of luggage
- chairs or loungers where people fall asleep
- bedding or bed clothes
- moving or storage boxes
- shipped items, especially if held at several locations or warehouses
Bed bugs do not have a preference between sanitary, messy, or unsanitary conditions.
They can, however, be found at higher rates in places, such as hotels, if infestations are not properly cleared.
