How The Bed Bug Bite Look Like

What Do Bed Bug Bites Look Like? Here’s Exactly How to Spot the Symptoms

If you wake up with a line of three to four itchy, swollen bumps, it could be due to bed bugs.

Waking up with a fresh set of itchy bug bites can bring on its own set of worries. What, exactly, was biting you in the middle of the night? Was it a spider? Mosquito? Or—possibly theworstcase scenario—could it have been bed bugs?

Although bed bugs might not be the first thing we think of when we wake up with a bite, the crittersdoget their food source from our blood—and will leave a little red bump in their wake after getting their fill.

But the trouble with identifying a bed bug bite—as is true for a lot of insects, including mosquitoes—is that it can be hard to identify the source of the bite, as everyone reacts differently to being bitten based on what their body’s immune response is. “Everybody’s going to respond differently,” saysTimothy Gibb, PhD, a clinical professor of entomology at Purdue University. “Same thing’s true with a mosquito bite. Some people are going to swell up and it’s going to itch. That same mosquito could bite someone else and it’s hardly noticeable.”

In fact, Gibb says some people may have no response when being bitten by a bed bug at all, based solely on how their immune system handles the bite. That’s why it can be difficult to determine whether your bite is the result of a bed bug just by looking at it.

But therearea few things that can tip you off to the fact that bed bugs are the culprit of your bites. Here’s what to know, including bed bug bites pictures to help you visualize the symptoms.

What do bed bug bites look like?

The key bed bug bite symptom to look for is a red, raised bump, says Gibb, similar in appearance to what you would get when bitten by a spider or a mosquito. But what sets bed bugs apart from other insects is that oftentimes,their bites will present in a line on one part or side of your body. This is the result of what’s called “probing.”

⚠️ Bed bug bites show up in a line, most often in a cluster of 3 to 4 bites.

“They probe the skin in several different places, I think probably to find best access to draw blood,” says Gibb. In fact, if you have screens on your windows—thereby keeping out other insects that might bite—but are still waking up with aline of 3 or 4 bites on your arm, it’s safe to suspect that bed bugs might be to blame, saysEdwin Rajotte, PhD, a professor of entomology at Penn State University.

Another way to determine if your bites are a result from bed bugs is to look for the insects themselves. They naturally like to hide in on your mattress, especially in the corners, near the head end, and in the cord that goes around it. They also like to camp out behind the headboard, behind any pictures on the wall, and in any electrical sockets.

Adult bed bugs are about the the size of an apple seed and are very flat from top to bottom—almost as thin as a piece of paper—with a brownish color, says Rajotte. Baby bed bugs are also brownish in color, but pinhead-sized. Another key identifier? Look for black spots on your sheets, mattress, and mattress cover, which could be bed bug feces.

Where do bed bugs bite, exactly?

Bed bug bites willmost commonly occur on the arms, neck, or trunk of the body, says Gibb, although they’ll bite anywhere they can find exposed skin. And—as their name suggests—bed bugs will bite you at night while you’re sound asleep.

“We’ve found it’s most active when people are most sound asleep, and that’s usually from about 2:00 to 4:00 in the morning,” says Gibb. “That’s natural for a parasite like that to do that because it’s going to protect it. People won’t see it, they won’t feel it. It makes their survivorship much more probable.”

Are bed bug bites itchy? Do they hurt?

Although some people will say a bed bug bite hurts somewhat—though not as intensely as the sting of a bee, for example—most complaints are due to the itching the bites cause, says Gibb. And that itching is due to the chemicals the bed bug inserts into your body during the bite, adds Rajotte.

“They’ve become what I consider the perfect parasite, because their mouthparts are kind of interesting,” says Gibb. “They will inject an anesthetic prior to biting, so people won’t feel it. And then they inject an anticoagulant that allows the blood to run easier for them to suck that up.” So while that system works great for thebugs, those left-over chemicals will usually lead to some uncomfortable itching on your end.

How long do bed bug bites last?

Although the duration and intensity of a bed bug bite will hugely vary from person to person, you typically won’t feel the effects of a bed bug bite—like itching and those raised red bumps—until mid-morning after a bite due to the anesthetic the bug injects, says Gibb. “So they certainly don’t feel it when the bite is occurring, but shortly after, probably within a day, for sure,” he adds.

From there, a bed bug bite will stay with you for typically at least 24 hours, though theycould last three to five days after the initial bite, says Gibb. At that point, the bite will then start to slowly dissipate.

How to treat bed bug bites

If you’ve received a bed bug bite (and the itching that comes along with it), chances are, you’re going to want to speed up the treatment process. But unfortunately, the best way to do that is also thehardestway to do it: not scratching the bite, says Gibb, which will just further irritate the area.

If you’re having trouble keeping your fingers away from the bite, you can also try using an antihistamine—think Benadryl or Allegra, which are meant to curb allergy symptoms—to help mute that itchy feeling.

And if bed bugsarethe cause of your bites, realize there’s no urgent need to panic. Yes, they might cost you a pretty penny and can be a pain to get rid of, but bed bugs can’t do any serious damage to your body.“They don’t kill people,” says Gibb. “A parasite would have a hard time surviving if it killed its host, and these do not.”

In fact, they don’t even transmit anything dangerous to you.“They’ve never been shown to transmit any diseases,”says Rajotte. “Unlike mosquitoes and ticks and things, which can transmit some pretty bad diseases, bed bugs do not. And so while they’re annoying and all that, they’re not going to harm your children or anything like that. They’re just annoying and you need to get rid of them.”

What Bedbug Bites Look Like — and How to Stop the Itch

Medically Reviewed by Ross Radusky, MD

Bedbugs, which are parasites known by the scientific names ofCimex lectulariusandCimex hemipterus, have been on the rise in the United States in the last decade or so. (1)

More on Insect Bites

As the name suggests, bedbugs bite at night when you’re asleep in bed, usually about an hour before dawn. (2) If you wake up with a bite, though, don’t immediately assume bedbugs are to blame. The bites look very similar to other insect bites. Here’s what to know to confidently identify bedbug bites and how to go about treating them.

Bedbug Bites Look Like a Swollen Red Spot — and They Often Itch

Bedbugs prefer to feed on the blood of humans (but they can survive on the blood of mice, rats, or other animals, too). You probably won’t catch the bugs in the act of biting, however, because the bedbug injects an anesthetic and an anti-coagulant to numb the area as it bites you. (3)

The bites can appear on any part of the body that’s exposed while you sleep — places like the back of your neck, shoulders, arms, and legs are common, says Steve Durham, president of EnviroCon Termite & Pest in Tomball, Texas.

For most people, bedbug bites result in itchy bumps where the bite occurred, within a day of being bitten. (4) The bites usually look like mosquito bites and will appear as a somewhat swollen red spot that might itch. (3)

But the bites will look different from person to person, and some people won’t develop any reaction whatsoever. “The same bedbug could bite two different people and one could have no reaction at all and the other can have an extreme reaction with a swollen arm or itchy rash,” says Eric Braun, a board-certified entomologist and business manager for the national pest control company Rentokil Steritech, who is based in Redding, Pennsylvania. Some people end up developing a rash that looks like eczema. (5)

It’s also possible that you won’t see a reaction the first time a bedbug bites since it sometimes can take the body a while to react. (6) Some people will have an immediate reaction, while for others it could take two weeks to emerge. Your body will likely become more sensitive to bedbug bites over time, and if you get bitten repeatedly, it could be only a matter of seconds before your body shows a response.

You may notice a single bite, while other times several bites will appear in a line. (3) “In most cases, they occur in clusters or zigzags of flat, itchy bites,” Durham says. “One bedbug will usually take more than one bite, so the severity of your infestation can have a big impact on the severity of your physical reaction to the bites.”

Bedbug bites differ from other bites in a few ways:

  • They can appear anywhere on the skin that’s exposed while you’re sleeping. Flea or chigger bites, on the other hand, usually only appear around your ankles, Durham says.
  • They sometimes bite in a zigzag pattern. (6)
  • Bedbug bites don’t normally have a red dot in the center, while flea bites usually do. (7)

Bedbug bites tend to stick around longer than mosquito bites, though they look very similar. (7)

Most of the Time Bedbug Bites Themselves Don’t Require Medical Attention

Bedbug bites don’t normally require treatment by a doctor, though there are a few precautions you should take at home. (8) Start by cleaning the area with soap and water to lower your risk of infection and to relieve itchiness. If the bites are itchy, pick up a corticosteroid cream at your local drugstore and apply it to the area. The bites generally will heal within a couple of weeks. (9)

Some people develop allergic reactions to bedbug bites, which can include a fever, difficulty breathing, hives, or a swollen tongue. Others may develop an infection where the bite starts oozing pus. If you experience either of these reactions or you develop blisters where the bites occurred, it’s a good idea to make an appointment with a dermatologist.

To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.

In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. "Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says. Those spots are left behind after a bedbug has been smashed.

You’ll likely only see them in their hiding spots or crawling across the floor since, unlike other insects, bedbugs cannot fly or jump. Durham says to check along the edges of your mattress. You may see the exoskeletons that bedbugs have shed as they matured, or you may notice a musty smell, both of which indicate there could be bedbugs in the area. It can also be helpful to check your bed with a flashlight during the middle of the night (since these crawlers tend to be more active at night.)

Bedbugs Slideshow: An Informative Look at Bedbugs

Don’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, they’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.

Feeding Habits

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.

Treating 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 bat—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

Everything You Need to Know About Bed Bug Bites

Bedbugs are small insects that feed on blood from humans or animals. They can live in your bed, furniture, carpet, clothing, and other belongings. They’re most active at night, feeding on people while they sleep.

Bedbugs can be 1 to 7 millimeters long. They’re flat, oval-shaped, and reddish-brown in color. They don’t have wings, so they rely on animals or humans to carry them from one place to another.

Although bedbug bites are rarely dangerous, they can be very itchy. In some cases, they become infected or cause an allergic reaction.

If you suspect there are bedbugs living in your home, it’s important to get rid of them.

Some people don’t develop noticeable symptoms from bedbug bites. When symptoms do develop, the bites tend to be:

  • red and swollen, with a dark spot at the center of each bite
  • arranged in lines or clusters, with multiple bites grouped together
  • itchy

Bedbugs can bite any part of your body. But they’ll usually bite areas of skin that are exposed while you sleep, such as your face, neck, arms, and hands. In some cases, the bites may develop into fluid-filled blisters.

If a bedbug bites your skin, you won’t feel it right away because the bugs excrete a tiny amount of anesthetic before feeding on people. It can sometimes take a few days for symptoms of bed bug bites to develop.

Bedbug bites often become noticeably red and swollen. Multiple bites may appear in a line or cluster in a small area of your body. The bites tend to be itchy. They may cause a burning sensation.

If you have bedbugs living in your home, they may not feed every single night. In fact, they can go multiple days without eating. It might take a few weeks to realize that the bites are part of a larger pattern.

Scratching bug bites can cause them to bleed or become infected. Learn more about the symptoms of an infected bug bite.

If you suspect there are bedbugs in your home, look for signs of them in your bed and other areas. For example, they often hide in:

  • mattresses
  • box springs
  • bed frames
  • headboards
  • pillows and bedding
  • cracks or seams of furniture
  • carpeting around baseboards
  • spaces behind light switches and electrical outlet plates
  • curtains
  • clothes

You may see the bugs themselves. You may also find drops of blood or small black dots of bug droppings in your bed. If you find bedbugs, call your landlord or a pest control company.

To contain and eliminate the infestation, it helps to:

  • Vacuum and steam-clean your floors, mattresses, furniture, and appliances.
  • Launder your linens, drapes, and clothing using the hottest settings of your washing machine and dryer.
  • Seal items that can’t be laundered in plastic bags and store them for several days at 0°F (-17°C) or for several months at warmer temperatures.
  • Heat items that can be safely heated to 115°F (46°C).
  • Fill gaps around your baseboards and cracks in furniture with caulking.

Several insecticides are also available to kill bedbugs. A pest control company may have access to insecticides or equipment that might be difficult for you to buy, rent, or use on your own. Find more tips for managing bedbug infestations and learn when to call a professional.

In most cases, bedbug bites get better within one to two weeks. To relieve symptoms, it may help to:

  • Apply anti-itch cream or calamine lotion to bites.
  • Take an oral antihistamine to reduce itching and burning.
  • Use an over-the-counter pain reliever to relieve swelling and pain.

In rare cases, bedbug bites can cause allergic reactions. If you develop signs or symptoms of a serious allergic reaction, call 911.

Sometimes, bedbug bites can cause an infection known as cellulitis. To reduce the risk of infection, wash the bites with soap and water and try not to scratch them. Learn when it’s time to visit your doctor for treatment.

In addition to over-the-counter medications, there are several home remedies that may help relieve the symptoms of bedbug bites.

To soothe bitten areas, it may help to apply one or more of the following:

  • a cold cloth or an ice pack wrapped in a towel
  • a thin paste of baking soda and water
  • certain types of essential oils

Although more research is needed, some studies suggest that camphor oil, chamomile oil, or some other types of essential oil may help relieve bug bites. Take a moment to learn more about seven essential oils that might help treat bites.

If you suspect that your baby or child has been bitten by bedbugs, check their sheets, mattress, bed frame, and nearby baseboards for signs of the bugs.

To treat bedbug bites on your baby or child, wash the bites with soap and water. Consider applying a cold compress or calamine lotion.

Talk to your child’s doctor or pharmacist before using topical steroid creams or oral antihistamines to treat the bites. Some medications may not be safe for babies or young children.

If your child is old enough to understand your instructions, ask them not to scratch the bites. To prevent scratching, it may also help to trim your child’s nails and cover the bites with a bandage.

Bedbug bites and fleabites are quite similar in appearance. Both can cause red bumps to form on your skin. Both can be very itchy.

When fleas bite you, they typically bite the lower half or your body or warm, moist areas around joints. For example, they may bite:

  • your feet
  • your legs
  • your armpits
  • the inside of your elbows or knees

Bedbugs are more likely to bite upper parts of your body, such as your:

If you suspect that bedbugs or fleas have bitten you, check for signs of the bugs in your home. Bedbugs often hide in the seams of mattresses, cracks of bed frames and headboards, and baseboards around beds. Fleas tend to live on family pets and in carpet or upholstered furniture.

If you find bedbugs or fleas, it’s important to treat your home or pet to get rid of them. Get the information you need to identify and treat infestations of these pests.

Bedbug bites and mosquito bites can both be red, swollen, and itchy. If you have a line of bites that appear in a small area of your body, they’re more likely to be bedbug bites. Bites that appear in no apparent pattern are more likely to be mosquito bites.

Both bedbug bites and mosquito bites tend to get better on their own, within a week or two. To relieve itching and other symptoms, it may help to apply a cold compress, calamine lotion, or other topical treatments. Taking an oral antihistamine can help as well.

It’s also possible to confuse bedbug bites with spider bites, ant bites, or other insect bites. Find out more about the differences between these types of bites.

Sometimes, people mistake hives for bedbug bites. Hives are red bumps that can develop on your skin as a result of an allergic reaction or other cause. Like bedbug bites, they’re often itchy.

If you develop red bumps on your skin that get larger, change shape, or spread from one part of your body to another in a short period of time, they’re more likely to be hives.

A small group or line of bumps that appear on one part of your body without changing shape or location are more likely to be bedbug bites.

If you develop hives along with breathing difficulties, dizziness, nausea, or vomiting, get medical help right away. You might be experiencing anaphylaxis, a potentially life-threatening allergic reaction. Learn more about anaphylaxis and other potential causes of hives.

Spider bites can be red and itchy, much like bedbug bites. But unlike bedbugs, spiders rarely bite more than once. If you only have one bite on your body, it’s probably not from bedbugs.

Spider bites often take longer to heal than other types of bug bites. Some spider bites can cause serious damage to your skin, especially if they get infected. To reduce the risk of infection, wash any bug bites with soap and water.

Some spiders are poisonous. If you suspect a poisonous spider has bitten you, get medical help right away.

Bedbugs can live in any home or public area. But they’re common in places that have a lot of people, a lot of turnover, and close quarters. You may be at increased risk for encountering bedbugs if you live or work in a:

  • hotel
  • hospital
  • homeless shelter
  • military barrack
  • college dorm
  • apartment complex
  • business office

Unlike some types of bugs, bedbugs don’t transmit diseases when they bite. But in some cases, bedbug bites can become infected. Potential signs and symptoms of an infection include:

  • pain and tenderness radiating from the bite
  • redness, swelling, or warmth around the bite
  • red streaks or spots near the bite
  • pus or drainage from the bite
  • dimpling of your skin
  • fever
  • chills

If have a bedbug allergy, you may also develop an allergic reaction after being bitten. This may cause painful swelling or intense itching around the bite. In some cases, it can also trigger a potentially life-threatening reaction known as anaphylaxis.

If you suspect that you’ve developed an infection or allergic reaction to a bedbug bite, contact your doctor. Get emergency medical care if you develop any of the following after being bitten:

  • nausea
  • vomiting
  • fever
  • chills
  • dizziness
  • trouble breathing

Bedbugs don’t just bite humans. They can also feed on family pets.

If you have a pet who’s been bitten by bedbugs, the bites will likely get better on their own. But in some cases, they might become infected. Make an appointment with a veterinarian if you suspect your pet has an infected bite.

If you hire a pest control expert to get rid of bedbugs in your home, let them know if you have a pet. Some insecticides may be safer for your pet than others. It’s also important to wash your pet’s bed, stuffed toys, and other accessories where bedbugs may be living.

What Do Bed Bug Bites Look Like (And How To Get Rid of Them Faster)

It can be difficult to identify bed bug bites because the red itchy bumps caused by bed bug bites look like flea bites or mosquito bites. Bed bugs usually come out at night and feed on the blood of humans. The tiny nasty pests can leave a cluster of bite marks on your face, arms, stomach, and legs. Some people only have a mild reaction to the bed bug bites and may only have a few small red dots. However, others have more severe reactions and are plagued by large red bite marks and an irresistible urge to scratch them.

Pictures of bed bug bites show groups of red bite marks on the body. Very often, the bite marks left by bed bugs are in straight lines or in a zig-zag and very rarely is there just one solitary red bite mark.

There are many effective natural home remedies to quickly get rid of the signs of bed bug bites. You can make your own natural treatments for insect bites with ingredients like witch hazel, apple cider vinegar, and aloe vera. The natural anti-inflammatory ingredients in those home remedies help to quickly relieve itching and promote healing.

In this article, you will learn how to identify bed bug bites and find out how to get rid of them quickly. You will also see images of bed bug bites to help you to spot the tell-tale signs that you have been bitten.

What do Bed Bugs Look Like?

The Latin name for bed bugs isCimex lectularius, or common bed bug. If you’ve ever seen a close-up picture of a bed bug you will see that they look quite scary. However, in reality, bed bugs are tiny pests that lurk in corners and crevices of beds, mattresses, and furniture. They are about the size of a small apple seed and many can be seen crawling around if you have an infestation.

Dr. Carol DerSarkissian on WebMD says that bed bugs have flat, brown, oval bodies. They don’t have wings but can quickly scurry over floors, ceilings, and walls. The parasitic insects live in groups and love to hide in dark places. If you have a bed bug problem in your home, you should check for signs of bed bugs in corners of your bed frame, along the seams of mattresses, along baseboards, and behind pictures. In fact, they will live in any crevice that is large enough to slide a credit card into. 1

The U.S. Environmental Protection Agency reports that bed bug eggs look like tiny white pinheads. As they go through their nymph stages they shed skins and these yellowish shells are a common sign to look for when checking for an infestation of bugs. 2

How to Identify Bed Bug Bites

On most people, bed bug bites look like itchy red bumps on their body. However, it can be difficult to know if the bite marks have been caused by bed bugs or not.

According to the Centers for Disease Control and Prevention (CDC), the symptoms of bed bug bites may not appear for a few days. Also, each person reacts differently to being bitten by these irritating pests. Some people show no signs of being bitten whereas other people have a severe reaction to the bite, and large bumps appear on the skin that itch severely. 3

However, Dr. Carol DerSarkissian on WebMD says that the only way to know for sure if the red bite marks have been caused by bed bugs is to look for signs of a bug infestation. That will confirm if the red spots that look like bed bug bites are in fact the result of bed bugs.

Bed Bug Bites – Signs and Symptoms

Images of bed bug bites generally show clusters of itchy red bumps on a person’s arms, neck, face, legs, and other areas of their body. Depending on the number of bed bugs that have infested your sleeping area and your reaction to them, bed bug bites also have other signs.

Doctors from the Mayo Clinic say that more often than not, bed bug bites will be in either a rough line or in a cluster of red marks. If they cause a severe skin reaction, the itching can be very intense. In rare cases, a person who has many bites and a severe allergic reaction should visit a doctor. 4

Doctors from the National Health Service say that, in some cases, the itchy red bumps on the skin can cause a rash or start to blister and fill with fluid. 5

However, it can be difficult to tell if the bites have been caused by bed bugs or another insect. Therefore, it’s important to know how to identify the difference between bed bug bites, flea bites and mosquito bites.

Bed bug bite vs flea bite

Flea bites and bed bug bites look very similar and cause itchy red marks on the skin. Even in pictures, it is hard to tell bed bug bites and flea bites apart. However, there are some differences.

The symptoms of flea bites generally appear on the ankles, feet and around the abdomen. As with bed bug bites, flea bite symptoms can also appear in small clusters. Dr. Carol DerSarkissian says that if you look closely at a bed bug bite you won’t see a small red dot in the middle as is characteristic of flea bites. 1

Bed bug bite vs mosquito bite

Both mosquito bites and bed bug bites can leave itchy welts on the skin. Doctors from the Mayo Clinic say that the symptoms of mosquito bites show up very soon after the bite; in fact, in only a few minutes, a puffy red bump usually appears. 6

Unlike bed bug bites that are painless, you may feel the mosquito bite and it might start to itch immediately. It is also more likely that the mosquito bite will blister and ooze a small amount of fluid.

Symptoms of Bed Bug Bites – Complications

Bed bug bite marks usually heal within 2 weeks and won’t leave any permanent mark on the skin. In some cases, there are complications associated with bed bug bites.

Of course, for many people, the appearance of red itchy welts on visible areas of skin like their face or arms is an unwanted complication of bed bug bites.

One of the most common, and potentially serious, complications that is seen with bed bug bite is a secondary skin infection. Dr. Stephanie S. Gardner on WebMD says that itching from bed bug bites can be so severe that constant scratching breaks the skin and germs get it. This can cause a bacterial infection in the bite mark. 7

Dr. Steven Doerr on eMedicnineHealth warns that some people experience severe allergic reactions to bed bug bites. Some of the signs of a serious allergic reaction include itching all over the body, tightness in the throat, chest pain, red bed bug rash that spreads from the bite area. 8

At least the good news with bed bug bites is that they don’t spread disease. The CDC states that bed bugs don’t spread disease and the most serious health threat is a lack of sleep from scratching and secondary skin infections. 3

Signs of Bed Bug Infestation

If you suspect that clusters of itchy red spots on your body are the result of pesky bed bugs, you should check for signs of an infestation.

First, you don’t have to worry that having bed bugs is a sign of uncleanliness or dirtiness. The CDC says that bed bugs only feed on blood and aren’t attracted to dirt. Bed bugs have been found in the cleanest of 5-star hotels. 3

To check for signs of bed bugs, you should look in areas where they tend to live. The U.S. Environmental Protection Agency says that tell-tale signs of bed bug activity are tiny rusty-colored stains on bed linen from bug feces or dried blood. You may also notice tiny yellow shed skins around your bed and sleeping area. 9

The next step to confirm if itchy red marks on your skin are from bed bugs is to find where the critters are hiding. You should check all joints and screw holes in your bed frame, around mattresses and box springs, and around the headboard.

How to Get Rid of Bed Bug Bites Fast

Cold compress

To quickly get rid of an intense itch in a swollen bump caused by a bed bug bite, you can use a cold compress. One excellent way to make a compress is by using a cold tea bag. Cold helps to relieve irritation from your skin by calming nerve endings, and tea helps to relieve itching and promotes healing.

A study from 2012 into the healing effects of tea found that compounds in black and green tea have an astringent effect. This helps to reduce itching in irritated, inflamed skin. 9 However, you don’t just have to use black or green tea bags. Research has also found that chamomile has soothing properties and is just as effective as hydrocortisone creams (often prescribed by doctors to reduce itching in insect bites). 10

How to use:

To quickly get rid of the irritation that bed bug bites cause using a cold tea compress, this is what you should do:

  1. Put a tea bag in a cup of boiling water for a few minutes. Remove the bag and cool it in the refrigerator.
  2. Place the tea bag on the red itchy bumps to relieve discomfort and irritation.
  3. Apply the cold compress 2-3 times a day for fast relief from bed bug bites and bed bug rash.

Aloe vera

Aloe vera also has properties that reduce itching and help to speed up the healing time of a bed bug bite. Aloe vera contains many properties to nourish your skin and relieve inflammation and irritation.

One study into the healing properties of aloe vera found that it has a soothing effect on irritated skin. It was found that aloe vera was just as effective as hydrocortisone creams in reducing itching and inflammatory responses in the skin. 11

How to use:

Aloe vera gel is great for helping bed bug bites to heal faster. This is what you should do:

  1. Use aloe vera gel with as few added ingredients as possible and liberally apply some gel to the bite marks.
  2. Massage the gel into the area around the bed bug bites to soothe the skin and stop itching.
  3. Apply the natural remedy 2-3 times a day to help your skin heal quicker and get welcome relief from the constant itching.

Tea tree oil

Tea tree oil will help to treat the itch in bed bug bites and help prevent secondary infections making the skin worse. Tea tree oil contains powerful antimicrobial compounds as well as properties that help to reduce inflammation and itching.

One of the benefits of using tea tree oil to quickly treat bed bug bites is that it helps soothe allergic skin reactions. For example, theBritish Journal of Dermatologyreported on a study into the antihistamine effect of tea tree oil. Histamine is released by the body as a response to allergens. It was found that applying tea tree oil to skin inflammation helped to soothe the allergic response fast. 12

How to use:

You can use tea tree oil as a spot treatment on one or two bed bug bites or you can mix a couple of drops of tea tree oil with coconut oil to apply to clusters of bed bug bites. This is what you should do:

  1. Put a drop of tea tree oil on the end of a cotton bud and apply to the itchy bed bug bite.
  2. Apply 2 times a day to help stop itching in the bite marks and prevent bacterial infections affecting the skin area.

For large clusters of bed bug bites, you can get relief by adding 2-3 drops of tea tree oil to a tablespoon of coconut oil. Apply 2-3 times a day to help your skin heal and treat any bed bug bite blisters that have formed.

You can also use tea tree oil to make a natural spray for bed bug eradication.
