What Are the First Signs and Symptoms of a Bed Bug Bite Rash?

It is very common for a bed bug rash to be mistaken for common household insects bites rash since a bed bug rash can look almost identical to those caused by other parasitic blood feeding insects such as mosquitoes, fleas, ants and lice.

In fact, most people do not know that they are bitten by bed bugs and may assume the rash as skin allergy without further notice. However the bites of bed bugs can be easily recognizable once you know what are the symptoms to look for.

The first tell tale signs of bed bug bites are the multiple small or raised red bumps on the skin that will always appear in a clustered pattern or in a row because of the tendency of the bloodsucking bugs to feed on the same location more than once.

The next tell tale sign to look for will be that you will get bitten every night while you are sleeping and develop large amount of these rashes every day, especially on the back, legs and arms which are common sites for bed bug bites.

Either way, for many people, these red bumps will often manifest hours or days after the actual biting. The bitten spots may soon begin to itch and if scratched, the bite area can become severly infected and inflammed.

How long a bed bug rash last is really dependent on the individuals being bitten.

Other natural remedies you can try to treat the rash include:

    Applying lukewarm water (preferably over 120 degrees F or 50 В°C) immediately to the bites area is also known to provide relief to some people.

Simply washing it regularly with antibacterial soap to keep bacteria from growing and causing infection.

Calamine lotion will help protect the skin as it heals. It will also speed up the drying of the rash and help the area heal faster.

Powdered oatmeal can be added to a lukewarm bath that is soaked in. It will provide relief from not only itching but reduce inflammations and irritation as well. It can also be made into paste and applied directly to the affect areas.

    Do bed bug bites itch? Not everyone reacts to a bed bug bite, but itching is one of the most common reactions for those who do. As with most insect bites that itch, it can be hard not to scratch where a bed bug has chomped down. But don’t scratch.

    The following articles answer questions such as “Why do bed bug bites itch?”, “How do I treat them?” and “What should I do and not do if I’ve been bitten?”


    The Centers for Disease Control’s FAQ sheet on bed bugs explains that as it bites, a bed bug transfers both an anesthetic and an anticoagulant through a straw-like mouth that it uses to feed.

    The anesthetic prevents the bite from immediately itching. The anticoagulant stops the blood from clotting at the site of the bite, ensuring your blood flows freely for a quicker feeding. When the anesthetic wears off, a bite may begin to itch as the body reacts to the saliva left behind.

    Scratching a bed bug bite can cause a secondary skin infection and should be avoided if possible.


    The American Academy of Dermatology (AAD) recommends a simple treatment plan for most bed bug bites:

    ‟Wash the bites with soap and water. This will help prevent a skin infection and help reduce itchiness. If the bites itch, apply a corticosteroid cream to the bites. You can get a weak form of this medicine without a prescription at your local drugstore. Stronger corticosteroids require a prescription.”


    If a person is hypersensitive to insect bites, or over-scratching causes an infection, the AAD recommends seeing a dermatologist to help treat the symptoms.

    Some skin infections can be difficult to treat at home. Signs you should seek treatment include blistering, a lot of bites, bites that have pus or discharge, or welts that become hives.

    So, do bed bug bites itch? Indeed, they can. Just try not to scratch them while you call Terminix®, and make sure the biting stops today.


    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.


    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.


    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.


    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.


    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:


    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).


    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.


    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.


    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.

    Shingles? Bed bugs?

    Shingles? Bed bugs?

    Here’s the story:

    Tuesday evening – felt like garbage during a yoga class, figured it was an off day. Achey pain along front/left muscles of neck. Monday and Tuesday were kinda shitty days overall.

    Wednesday am – felt a hive-like itch on upper right arm. Found a batch of itchy bumps on neck (right side) shortly after (see photos), and another single bump on right forearm.

    Wednesday pm – another single bump appears on right bicep.

    Thursday – start using hydrocortisone, itching goes away.

    Monday – family doctor says shingles could be a possibility but there is no distinct spread of blisters. Doesn’t think it’s bed bugs either, but leans more towards some sort of weird bug over other conditions.

    Tuesday evening – right after hot yoga, two more welty/hivey bumps on right forearm near elbow. Itchy af. They got bigger overnight (see photos).

    I can’t tell if these are shingles, bb bites, other bugs, heat/sweat rash, stress, etc.

    There are no signs of bugs in my apartment, I’ve had interceptors on my bed legs and diatomaceous earth everywhere for months because my apartment building is old af. Also, no flu-like symptoms that would make shingles an obvious choice.

    Your input is greatly appreciated! I’ll go to the doctor again once/if new bumps appear.

    That doesn’t look like shingles. From your symptoms and picture it looks like scabies. Also, a girl I used to work with had scabies and her doctor told her it was likely from her hot yoga class. I would definitely go get that checked out ASAP!

    I hope you feel better soon.

    those neck ones definitely look like my shingles did. sounds like they started about 8 days ago, about a week in for me they were starting to look distinctly like blisters, filling with liquid and very painful. do they hurt? have you been especially stressed/tired/sick/immunocompromised?

    OP did you resolve this, I’m dealing with a similar condition and could benefit from what youve learned/figured out

    So I ended up pulling the trigger that same week under the assumption it was bed bugs to gtfo of my apartment, where the landlord left apartments to decay and neighbours had scares with bugs and other pests. Spent over $1000 to heat treat all our stuff in the moving truck and have not had any potential bites since, just the remaining anxiety and phantom itches.

    But, I also never really found tell-tale signs of the bugs in that apartment/my stuff. And, I sometimes get little individual bumps in the same area on my neck, but they look more like irritated follicles and occur usually right after a hot yoga class (sweat can do this), or I’ll get a random hive on my jaw-line with the same itch. I haven’t had anything like the big blisters from the original post.

    I’m just operating on the idea now that most likely, there were bed bugs, but my anxiety and lifestyle were mixed in to make the whole thing a little more uncertain and confusing. I think the only thing I’ve really taken away from it all is that I couldn’t handle even the potential infestation and was privileged to be able to get out quickly and ensure to the best of my abilities that the next place would be free from the real or imagined problem. I’m sorry I don’t have anything concrete, but please take care of yourself whatever it is – the anxiety from this was debilitating for a while and still creeps in sometimes.

    How long does it take for bed bugs to die without human contact

    Scientific studies have shown that bed bugs (cimex lectularius) adults can live as long as 400+ days without feeding in a laboratory at low temperatures.

    Adult bed bugs can live for more than a year and it was found that there can be up to four successive generations per year. As for nymphs the life span is shorter than adults.

    • Adult bed bugs can live 14 months without feeding
    • Nymphs live 5 months without blood meal
    • Females need first blood meal to lay eggs

    Starving a bed bug is not an effective strategy in removing an infestation.

    Pest management professionals follow specific guidelines to get rid of bed bugs permanently . These procedures will help identify the necessary effort to quickly remove a bed bug infestation in any size property.

    To help reduce outbreaks please share with friends and family.

    Do bed bugs die if they do not feed?

    Bed bugs do require to feed (blood meal) in order to survive, yet there is a 14 month life span of a adult bed bugs without human contact found in scientific studies.

    The complete life cycle of a bed bug requires at least one blood meal before molting to the next stage, this again depends on temperature and availability of food/blood meal.

    Keep in mind development occurs more rapidly at temperatures between 70° and 82°F.

    Can bed bugs live in a vacant house?

    Due to an adult bed bug life cycle can last 400+ days without a host. It’s very common bed bugs can live in a vacant home.

    Due to the feeding cycle of bed bugs, they may migrate to where a blood meal can be found. This may be the cause of an infestation from a neighbors home that is in your living vicinity.

    What is the average lifespan of bed bugs?

    The life stages of a bed bug are based on five nymphal stages (not including the egg). Each stage requiring a blood meal before molting to the next stage.

    • Egg – Eggs are white and oval shaped (about 1/16 long)
    • Tiny white nymph – Difficult to see (about 1.5mm) Look like specs of dirt until they move
    • Light nymph with black spot – (about 2mm) Noticeable black spot in abdomen area
    • Light brown nymph – Lager in Size (about 2.5mm) Resembles an apple seed in shape
    • Medium brown nymph – Size increases (about 3mm) smaller version of the adult bed bug
    • Darker brown nymph – Larger in size (about 4.0mm) More pronounce black spot on abdomen
    • Adult – Reddish brown “rust color” flat oval shaped body (about 4.5mm)Egg

    How long can a bed bug live with a host

    Can bed bugs or eggs travel on the botshoesr to of your shoes

    Yes they can, it is very common they travel from suitcases into your home. Another way we have a lot of readers get them is from their kids backpacks in school. They then come home with the bed bug in the back pack and that night, they begin burrowing into the beds and start feasting. A week later you begin to start noticing the bites.

    So its very common these bed bugs migrate on shoes, luggage, clothing, etc.

    I had a K 9 detect bed bugs in 1 room in my apartment. I had to pack up the entire apartment in plastic bags in the middle of the flood. I had 3 treatments. The last treatment was in November. there has been no known activity since. We can I finish unpacking and know that the treatments were successful

    AWESOME. to hear your bed bug issue is gone. If your not feeling bites for a two week period or so, you can assume a success.

    Although… please be aware, neighbors, public transportation, kids backpacks… other external things outside your home. This can bring back bed bugs. It’s possible… not always likely but it happens.

    So its always recommended, while you do a monthly cleaning, simply SPOT-Treat your beds, couches, and walls, clothing areas with GreenBeanBuddy residual bed bug spray. This will prevent the pests from migrating from any outside sources.

    Thankyou for sharing your story, we’re so thrilled you got rid of your bed bugs! We love it when customers tell us this.

    Nobody seems to address specifically: Can bedbug EGGS lie dormant to hatch at a later time, when conditions are more favorable? How long can they last? Will adding moisture to dry old bedbug eggs reactivate them?

    Hi Tom, thanks for reaching out. I will be happy to answer your questions. We have bed bug specialist on staff that confirm the answers as well.

    As for EGGS being dormant and hatching, yes nymphs(hatchling bed bugs) do lay dormant then hatch later. This is why we recommend a re-treatment around the 7 day point, because this 2nd treatment cycle will get the nymphs that look to feed. These are usually very tiny ones you cannot see very well, yet you feel the bites. (And their bites are usually the more painful ones because they do not inject you with the numbing agent that the large bed bugs do when feeding.).

    EGGS cycle usually hatch every 7 to 14 days.

    Adding moisture to dry eggs will not re-activate them. In fact, Green Bean Buddy is so effective because the formulation kills bed bugs using a dehydration method that seals out the bed bugs moisture from the inside out, thus causing them to die without becoming immune to our formulation. So the nymphs are affected in the same way.

    Thanks for contributing, your questions will help the community and assist us in which guides we should add to help more of bed bug victims and our clients.

    Let me know if you have any more questions.

    I noticed there are bed bugs in my house and I used pesticides on them, though most of them died but I realized their eggs were still there, my question is, can the pesticide kiilbthe eggs? If it can’t how long can I one use the pesticides on d nymph

    Most pesticides will not kills the eggs.

    You will notice after a treatment, another cycle occurs of bites a few days later… likely 5 to 7 days. This is the hatchlings from the eggs and these are the most painful bites. The little nymphs do not have a numbing agent like the larger adults when they bite, so you feel it.

    What You Want To Do For The Eggs:

    We found a way to get rid of the hatchlings and egg cycle with our residual bed bug treatment. You simply spray Green Bean Buddy bed bug killer on any surface (clothing, bed, boxspring, and around the bed on the floor). This will prevent and kill these pests from reaching you. In fact most will avoid the area of treatment and if hatchlings get near it they die. So we recommend a nice barrier every few days until all the hatchlings are gone.

    which is the most efficient pestside for bedbugs…Iv treated mine for 6months with no success

    Hi Lizzy, it’s a process. I would advise the following steps below. It’s important to do a treatment and stay consistent. The reason of being consistent is because these bed bugs can hide in many locations. So it’s important to treat all the areas. To combat this difficulty, you may wish to consider a residual bed bug treatment spray. This allows you to spray the areas, then it leaves a clear residual to protect from re-infestations. This is how health facilities, resorts, and pest managers are using the bed bug treatment sprays.

    I think one reason they been around for 6 months is you may not know the true source of the problem. This is very common. We’ve found the bed bugs hiding in picture frames way up on the wall. Then other times they were in electrical outlets. And of course… neighbors or when you travel on public transportation. They literally can hitch a ride.

    We had someone who was a mechanic, and they worked in a car which had bed bugs. He didn’t know that they were jumping on his clothes from the vehicle he was working on. So they can come from multiple sources. This is why we have had such great success in residual bed bug spray. The simple fact that is kills and then spray along your doors, windows, walls, bed, couches, linens, etc. This will be like a shield which these bed bugs will either come near and die or simply evacuate due to the formulation.

    Steps To Follow & Products To Use:

    1. Identify what a bed bug looks like – so you can identify the different sizes of them.

    2. Where do bed bugs hide – so you know where to treat.

    3. How to treat bed bugs yourself – You can use these procedures during treatment.

    Lastly, how to keep bed bugs away permanently with re-treatment. This is because re-infestations can come from external sources.

    You can consider a Residual Bed Bug Spray to combat the problem. You may also want to consider a bed bug steamer as well.

    Thanks for sharing with the community. Let me know if you have other questions. I think the guides will definitely help, just be consistent and remember when doing a treatment, SPOT TREAT… don’t drench. This will give you more product to use later on just in case you need to re-treat or want to prevent the infestation after its gone.
