How To Determine If Bed Bug Bites
How to Find Bed Bugs
If you have a bed bug infestation, it is best to find it early, before the infestation becomes established or spreads. Treating a minor infestation, while an inconvenience, is far less costly and easier than treating the same infestation after it becomes more widespread.
However, low-level infestations are also much more challenging to find and correctly identify. Other insects, such as carpet beetles, can be easily mistaken for bed bugs. If you misidentify a bed bug infestation, it gives the bugs more time to spread to other areas of the house or hitchhike a ride to someone else’s house to start a new infestation. Learn about identifying bed bugs.
Bites on the skin are a poor indicator of a bed bug infestation. Bed bug bites can look like bites from other insects (such as mosquitoes or chiggers), rashes (such as eczema or fungal infections), or even hives. Some people do not react to bed bug bites at all.
Looking for Signs of Bed Bugs
A more accurate way to identify a possible infestation is to look for physical signs of bed bugs. When cleaning, changing bedding, or staying away from home, look for:
- Rusty or reddish stains on bed sheets or mattresses caused by bed bugs being crushed.
- Dark spots (about this size: •), which are bed bug excrement and may bleed on the fabric like a marker would.
- Eggs and eggshells, which are tiny (about 1mm) and pale yellow skins that nymphs shed as they grow larger.
- Live bed bugs.
Where Bed Bugs Hide
When not feeding, bed bugs hide in a variety of places. Around the bed, they can be found near the piping, seams and tags of the mattress and box spring, and in cracks on the bed frame and headboard.
If the room is heavily infested, you may find bed bugs:
- In the seams of chairs and couches, between cushions, in the folds of curtains.
- In drawer joints.
- In electrical receptacles and appliances.
- Under loose wall paper and wall hangings.
- At the junction where the wall and the ceiling meet.
- Even in the head of a screw.

Bedbugs are small, oval, brownish insects that live on the blood of animals or humans. Adult bedbugs have flat bodies about the size of an apple seed. After feeding, however, their bodies swell and are a reddish color.
Bedbugs do not fly, but they can move quickly over floors, walls, and ceilings. Female bedbugs may lay hundreds of eggs, each of which is about the size of a speck of dust, over a lifetime.
Immature bedbugs, called nymphs, shed their skins five times before reaching maturity and require a meal of blood before each shedding. Under favorable conditions the bugs can develop fully in as little as a month and produce three or more generations per year.
Although they are a nuisance, they are not thought to transmit diseases.
Where Bed Bugs Hide
Bedbugs may enter your home undetected through luggage, clothing, used beds and couches, and other items. Their flattened bodies make it possible for them to fit into tiny spaces, about the width of a credit card. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy access to people to bite in the night.
Over time, however, they may scatter through the bedroom, moving into any crevice or protected location. They may also spread to nearby rooms or apartments.
Because bedbugs live solely on blood, having them in your home is not a sign of dirtiness. You are as likely to find them in immaculate homes and hotel rooms as in filthy ones.
When Bedbugs Bite
Bedbugs are active mainly at night and usually bite people while they are sleeping. They feed by piercing the skin and withdrawing blood through an elongated beak. The bugs feed from three to 10 minutes to become engorged and then crawl away unnoticed.
Most bedbug bites are painless at first, but later turn into itchy welts. Unlike flea bites that are mainly around the ankles, bedbug bites are on any area of skin exposed while sleeping. Also, the bites do not have a red spot in the center like flea bites do.
People who don’t realize they have a bedbug infestation may attribute the itching and welts to other causes, such as mosquitoes. To confirm bedbug bites, you must find and identify the bugs themselves.
Signs of Infestation
If you wake up with itchy areas you didn’t have when you went to sleep, you may have bedbugs, particularly if you got a used bed or other used furniture around the time the bites started. Other signs that you have bedbugs include:
- Blood stains on your sheets or pillowcases
- Dark or rusty spots of bedbug excrement on sheets and mattresses, bed clothes, and walls
- Bedbug fecal spots, egg shells, or shed skins in areas where bedbugs hide
- An offensive, musty odor from the bugs’ scent glands
If you suspect an infestation, remove all bedding and check it carefully for signs of the bugs or their excrement. Remove the dust cover over the bottom of the box springs and examine the seams in the wood framing. Peel back the fabric where it is stapled to the wood frame.
Also, check the area around the bed, including inside books, telephones or radios, the edge of the carpet, and even in electrical outlets. Check your closet, because bedbugs can attach to clothing. If you are uncertain about signs of bedbugs, call an exterminator, who will know what to look for.
If you find signs of infestation, begin steps to get rid of the bugs and prevent their return.
Getting rid of bedbugs begins with cleaning up the places where bedbugs live. This should include the following:
- Clean bedding, linens, curtains, and clothing in hot water and dry them on the highest dryer setting. Place stuffed animals, shoes, and other items that can’t be washed in the dryer and run on high for 30 minutes.
- Use a stiff brush to scrub mattress seams to remove bedbugs and their eggs before vacuuming.
- Vacuum your bed and surrounding area frequently. After vacuuming, immediately place the vacuum cleaner bag in a plastic bag and place in garbage can outdoors.
- Encase mattress and box springs with a tightly woven, zippered cover to keep bedbugs from entering or escaping. Bedbugs may live up to a year without feeding, so keep the cover on your mattress for at least a year to make sure all bugs in the mattress are dead.
- Repair cracks in plaster and glue down peeling wallpaper to get rid of places bedbugs can hide.
- Get rid of clutter around the bed.
If your mattress is infested, you may want to get rid of it and get a new one, but take care to rid the rest of your home of bedbugs or they will infest your new mattress.
While cleaning up infested areas will be helpful in controlling bedbugs, getting rid of them usually requires chemical treatments. Because treating your bed and bedroom with insecticides can be harmful, it is important to use products that can be used safely in bedrooms. Do not treat mattresses and bedding unless the label specifically says you can use them on bedding.
Generally it is safest and most effective to hire an experienced pest control professional for bedbug extermination.

How to Identify Bed Bug Bites—and How to Treat Them
Wake up with reddish welts or itchy skin? The culprit may be a bed bug hiding under your bed. These are the signs a dermatologist and entomologist look for.

Unfortunately, a bed bug bite has no telltale sign, according to a review published in theAmerican Society for Microbiology. The reaction to bites varies tremendously from one person to the next. Some people will have no reaction or just minor itching and mosquito-like bumps in one area; others will get dramatic red raised welts all over. “It depends on the number of feeding bugs on the body, how long the person has been suffering bites, and also where the bites are located,” says Jody Green, PhD, an urban entomologist at the University of Nebraska-Lincoln.
Five stages of post-bed bug bites
If you have evidence of bed bug bites on your skin, it’s due to your body’s allergic response, according to the U.S. Armed Forces’ 2019 Pest Management Board: Technical Guide #44. That response can take a few different forms: little to no reaction; an immediate reaction—often a red spot with minor discomfort; a delayed reaction in which red weals turn up within 14 days that trigger intense itching that can last two to five days; or, unfairly, a combination of immediate and delayed reactions. This makes it tough to know what’s gnawing on you without the help of an entomologist or dermatologist. Although this guide to bug bites may help.
Familiar signs of bed bug bites
While there is no exact way to tell what bug bit you, dermatologist A. Yasmine Kirkorian, MD, an assistant professor of Dermatology & Pediatrics, Children’s National Health System, says there are some patterns doctors look for: “Bed bugs typically bite several times in a row so people may notice several red itchy bumps grouped closely together, a pattern sometimes called ‘breakfast, lunch, and dinner,’” she explains. “They can occur anywhere on the body; bed bug bites on the face may cause intense swelling including of the eyelid.” A small study found that 72 percent of people who were bitten by bed bugs had itchy red welts, 50 percent had redness or discoloration, and 28 percent had itching with no welts. Call your doc or dermatologist and look for these signs of bed bugs in your house.
It can’t be bed bug bites
Let’s say you are sleeping in the same bed as your partner and your partner wakes up with bites but you don’t. Must not be bed bugs, right? Sadly, it still could be. “The most challenging thing about bed bug bites is that there is are people who do not react to bed bug bites, so they have no adverse skin responses and have no idea that they are being fed upon while they are sleeping,” says Green. One survey found that nearly one in three people had no reaction to bed bug bites. When the researchers broke out reactions by age, they found that 42 percent of people over 65 had no reaction. Bites or no bites, this is how bed bugs could get in your bedroom.
Bed bug bite treatment
People who do react to bed bugs often have intense itching. “Once a patient has been bitten, it is difficult to eradicate the itching. Over-the-counter anti-itch creams that contain one percent pramoxine can help,” says Dr. Kirkorian. Try Aveeno with pramoxine and calamine. Oral antihistamines such as Zyrtec and Benadryl may be effective too, says Dr. Kirkorian. But if your itching persists, your dermatologist or doctor might prescribe topical steroids such as triamcinolone and fluocinonide.
Just thinking about bed bugs can wreck your sleep, as well. Talk to your doctor if you start suffering from insomnia. “A sedating antihistamine such as Benadryl could be safe to use,” says Dr. Kirkorian.
Home remedies for bed bug bites
Before you commit to natural bed bug treatment, remember to practice good hygiene and caution, advises Larry Bishop, MD, a dermatologist with Health First Medical Group: Be sure to wash the area with soap and water first to reduce the risk of infection; if the area appears irritated or develops a rash, stop using the treatment and see a doctor. For remedies, Dr. Bishop suggests trying peppermint oil: “It works by two mechanisms—the peppermint oil is a vasoconstrictor (blood vessel constrictor), which lessens the pain and irritation from bed bug bites. Additionally, the peppermint works as a soothing agent by gently stimulating the nerves around the bite.” Try adding a few drops to a warm bath; if you want to apply it to the bites, dilute it first with an oil such as coconut, jojoba or olive.
Lemon balm is another favorite for bug bites. Crush or roll the leaves with your fingers to release the juice, apply it to the bites, and wrap with a bandage. “It works by having soothing properties and antibacterial properties,” Dr. Bishop says. Finally, there’s household ammonia—research suggests that it can help with itchy bites. It may not smell great, says Dr. Bishop, but if you put a little on a cotton ball and dab it on the area right away, it can help. “It works by neutralizing the proteins that are in the saliva of the bed bugs.” The saliva is what produces the allergic reaction in some people, and the quicker you neutralize it, the better.
When to see the doctor
Your bed bug bites will generally clear up on their own, but if you itch them the scratching can lead to secondary infections. “The initial bite may be a portal for bacteria to enter the skin. If a patient develops a worsening red bump, pus drainage, a fever, or other signs of systemic illness, they should seek urgent medical attention,” advises Dr. Kirkorian. Then, find out how to get rid of bed bugs.
9 SYMPTOMS AND SIGNS OF BED BUGS
Bed bugs are a nasty and uncomfortable problem. Signs and symptoms of bed bugs can be hard to detect at first, and even trickier to treat. To the untrained eye, bed bug bites can be confused with those of other biting insects.
Here are nine easy signs help you know if you have a bed bug problem.
RED, ITCHY BITES
People don’t often consider bed bugs until they’ve left their mark. The appearance of flat, red welts in zigzag lines or small clusters is a key sign of bed bugs on humans. Bed bugs can also leave their bites in straight rows and, while they don’t spread diseases to humans, their bites are quite irritating and scratching them can lead to bleeding and infection.
Bed bugs are most often found in the bed, where humans spend most of their nights. It makes logical sense for bed bugs to be most active at night while humans are in bed with them. Should you find yourself developing those itchy welts while laying in bed sleeping (or trying to sleep), it’s likely bed bugs are the problem.
MARKED ARMS AND SHOULDERS
Bed bugs tend to feed on exposed skin such as that on your arms and shoulders, which you may tend to leave uncovered while sleeping. This is different from, say, fleas and chiggers, which tend to bite around the ankles.
A BUGGY BED
The first sign of a bed bug problem is obvious: the bed. After bed bugs feed on humans, they’ll leave behind blood stains resembling small rust spots. These will usually be found near the corners and edges of the bed. Bed bugs also shed their skin, or molt, several times as they mature, so you may find their oval brown exoskeletons during your search.
THE NOSE HAS IT
A strong, unpleasant, musty odor like that of a wet towel is another common bed bug symptom. Bed bugs release pheromones, and when in large numbers, the smell can be quite strong. Should you find your bedroom smelling like a dirty locker room, you may want to perform an inspection.
Remember, bed bugs aren’t confined to your home. They can be found wherever you sleep, including hotel rooms.
Here are some quick inspection tips to help you avoid a serious problem, whether on the road or at home:
INSPECT THE BED
Strip the mattress and box spring and thoroughly inspect the corners and seams. Use a magnifying glass and a flashlight. You’re looking for rust-colored, reddish-brown blood stains and/or small brown ovals (molted bed bug skin).
INSPECT THE ROOM
After searching the bed, it’s time to move to the rest of the room. Check anything upholstered, including chairs, couches, curtains and the edges of the carpet. Look in and behind dressers, underneath the bed and if possible, behind the headboard. Always be on the lookout for the signature reddish-brown spots.
OPEN THE CLOSET
Bed bugs can also cling to clothing, which is how they can travel and spread so adeptly. Be sure to look in your closets and check your clothing thoroughly. Bed bugs on clothes means bed bugs on humans.
USE YOUR NOSE
As stated above, one way detect bed bugs is their smell. The scent of their pheromones can be quite strong. It’s often described as a musty odor.
Since it’s possible for people to go for long periods without being aware they have a bed bug infestation, knowing the key bed bug symptoms and how to find these pests will go a long way in combating them.
How to Tell if You’ve Been Bitten by a Bed Bug
Bed bug bites usually appear as small red welts in zigzag lines or small clusters. Learn more about beg bugs and how to tell if you’ve been bitten.
Bed bugs are a notoriously sneaky nuisance. An infestation can happen to anyone, and it may take days before you even realize these pests have set up camp in your home. Here are some signs to tell if bed bugs have been using you as their midnight snack:
Are bed bug bites visible?
Like bed bugs themselves, their bites can be tricky to identify. Initially, the bites are completely painless, and it could take days to develop any reaction on the skin. Some people will have no physical reaction at all to bed bug bites. If no marks develop on the skin but you still suspect you may have an infestation, then the tiny blood stains the bugs leave behind on the bed after feeding could be the only sign you’ve been bitten. Be sure to take steps to check your room thoroughly.
What do bed bug bites look like?
When bites do show, they will most likely appear as small red welts in zigzag lines or small clusters. These bites can also be mistaken for the bites of other insects, like mosquitoes. Unlike flea bites, which are primarily around the ankles, bed bug bites can appear on any part of your exposed body. You will often find similar telltale signs in bed bug bites. The bites will cause localized itching, which in some cases can be severe. Over time, people may become increasingly sensitive to bed bug bites, so the red welts and itching can grow in intensity the more often you are bitten.
What are Issues Associated With Bed Bugs?
If the infestation persists, bed bugs bites can also disrupt your sleep schedule and lead to insomnia and anxiety. Ifsigns of an allergic reactionoccur, such as hives or severe itching, medical attention may be needed.
Bed bugs do not attach themselves to their host. Instead, they feed in brief intervals and then go back into hiding. Therefore, bite marks and telltale stains are powerful clues in identifying the presence of bed bugs. Pictures of bed bug bites are helpful in this process.
