Bed Bug Pictures


Bed bug pictures are located throughout the page. The pictures are divided into easy to identify sections to help determine the size and shape of the bug, the different life stages you may find and help you determine if you have have an infestation and what to do next.

What do bed bugs look like?

By examining the bed bug pictures you will see that bed bugs are small insects with oval shaped bodies, six legs and two antennae. Their coloration will vary depending on their age as well as whether or not they have fed recently. View the bed bug pictures to get a better look at the shape, size and color variations. Nymphs (young bed bugs) are semi-translucent. When they feed they fill with blood, making their belly a dark brown and sometimes causing a spotted pattern where the blood is visible inside their abdomen. Adult bed bugs will be either a light brown with a flat, oval belly if unfed or a deep brown/red color with an engorged belly if they have fed.

Do you think you could have Bed Bugs? What should you do?

If you find bugs that look like the pictures here, or if you’ve been travelling recently and have returned with bug bites, you should be aware that you may be infested with bed bugs.

Bed bug infestations have risen dramatically recently, spreading throughout the globe as their pesticide resistance increases. Anyone who travels is especially at risk for bed bug infestation, no matter how nice of a hotel you stay at. They’ve also spread into public spaces, infesting buses, libraries, hospitals, movie theaters and more. According to pest control professionals  bed bug treatments have increased by over 9000% in the last decade alone.


The good news is bed bug infestations can be prevented and eliminated with fast, inexpensive heat treatment. You can use ZappBug quickly and easily to make sure you don’t bring bed bugs home with you, and to kill any bed bugs that may have already made it to your home.

If these bugs look familiar you should check out how to kill all bed bugs with ZappBug’s heat treatment chambers and our free 8-Step Approach on how to get rid of of Bed Bugs.



The bed bug’s body size also varies through their lifetime. Nymphs or juvenile bed bugs range from the size of a bed bug egg (0.09 inches, 2.5mm) to the size of full adult bed bugs at ( 0.18 inches, 4.5mm). For reference, 0.1 inches is slightly over the thickness of a quarter. Adult bed bugs are approximately the size of an apple seed.


What do bed bug eggs look like?

Bed bug eggs are small (around 0.1 inches, 2.5mm) long and appear white or semi-transparent, similar to a grain of uncooked white rice. They will be sticky to the touch and usually clustered together. You can also find shed egg shells after the infant bed bugs have hatched, but as these are very small and can resemble general debris you should look for active bugs and eggs as well.

On average female adult bed bugs will lay 1-5 eggs per day. They can be laid on almost any surface but are typically found in cracks or rough surfaces, especially around your mattress seams. They hatch within about a week. Over her lifetime, a female bed bug can lay up to 500 eggs. This and the fact that bed bugs are good at hiding allows bed bug populations to spread and grow quickly.

You can quickly stop the eggs from hatching with a non-harmful heat treatment. Learn more.


Bed Bug Front Legs

Their front legs bend forward. Bed bugs are insects and therefore have six legs, three on each side. Their legs are clustered in the front of their body, with their large abdomens behind their third set of legs. They also have large antennae that extend straight out to the sides of their heads, beyond the curl of their front set of legs


Bed Bug Bodies

Bed bug bodies have a very distinctive body shape. Notice the oval, almost egg-shaped body shown in the illustration. This is what you want to look for and the majority of your bed bugs (especially all nymphs) will have this shape. Adult bed bugs are capable of ingesting several times their body weight worth of blood, so their shape can change as they feed. They will go from relatively flat to more round, with an engorged abdomen. In rare cases they may have a more elongated appearance instead of the rounded oval seen here, but that will fade as they digest their food. Bed bugs that have fed recently are the most dangerous because they may be prepared to lay eggs.



What do dead bed bugs look like?

After treatment dead bed bugs will appear shriveled and curled up, with their legs and sometimes their heads curled into the middle of their body. In heat treatment they will often cluster together into a pile, as seen in this picture taken in the aftermath of heat treatment using a ZappBug Room. If you’re treating with pesticides or other products the bed bugs can shed their skin in an attempt to prevent death.



Bed bugs leave signs of infestation that are very useful to help identify them. The most obvious of these is the dark stains similar to blood left by their feces. These will be especially evident in the areas where the bed bugs spend most of their time, such as the underside of a mattress. You should also be on the lookout for eggs and molted shells, which will often be in the same location as staining. If the infestation is severe enough you may notice a characteristic smell that has been compared to sweet moldy gym socks or rotting raspberries, although some have contested that it’s more like coriander. While it’s uncommon for the smell to be notable it’s very evident to dogs and there are now many canine detection services that can help you find out if you do have an infestation.

Remember that when you’re looking for bed bugs it’s best to find an actual bug to confirm infestations; the signs above are helpful but it’s easy to become hyper-vigilant and assume that any general debris is a sign when you’re stressed out about bed bugs.



If you find bugs with both curled front legs and a distinctive, oval body shape then there is a good chance that they are bed bugs. We highly recommend that you take a proactive approach to the situation and follow our 8-Step Approach to Get Rid of Bed Bugs. It’s a completely free guide packed full of information on the easiest and most effective ways of fighting bed bugs.

    My daughter is a care giver and one home she is in regularly and over night once a week, has a bad bed bug infestation. The bugs just roil out of the walls. I am terrified of her bringing them here in her clothing! She usually puts her work clothes on the back porch when she gets home. If there are bugs in her clothes, is the back steps far enough from the house to keep them from seeking a warm place (my home!?)
    Thank you very much!!!

    My husband and I have been fighting bed bugs for months, now. We have 2 small children and money is tight. Other than heat and alcohol, what are effective ways to combat them without hurting the kids and pets? Also, is there a way to prevent another infestation? This is our second time doing this.

      Hello Melissa,

      Food Grade or Pet Grade Diatomaceous Earth is another non-toxic option to help you treat a bed bug infestation. We have information available about DE in our 4th step in the 8-step approach on our website. The best preventative method we would suggest is heat treating your items after traveling or if you been in a populated area.

    We got bed bugs 2 weeks ago from hand me down clothes. I found a mature one crawling on me 2 days after the clothes bag was dumped onto our couch. We had chemical treatment done 1 week ago over the entire house and now I just found 1 spot in my couch with living nymphs and eggs. Is it safe to assume they did not spray this spot? We are literally out of money after the last treatment. It’s only been a week and a half since the treatment and can’t have them do a second treatment until 30 days after… what do we do?

      Hello Anon,

      I would contact the company that did the treatment and let them know that you are still seeing bed bugs and make sure they do the follow-up treatment. Also, you can treat the couch with Diatomaceous Earth, here is a link to our 4th step in our 8-step approach explaining how to use Diatomaceous Earth. Let us know if you have any other questions.

    I live in an apartment building and have recently discovered a bug infestation. On occasion I would see a bug on the carpet for which I thought was a tic. I’m fairly certain my entire apartment building had bed bugs but I also came across information about carpet beetles. My question is tgw bugs I have hace veen seen on numerous places, mainly in secluded areas, but these bugs seem to stick and die at some point to wood furniture for example. Do bed bugs do this and if not what type of bug leaves this type of sign?

    • ZappBug
      ZappBug says:

      Hello Tammy,

      Have you noticed any bites? Bed bugs are often hard to spot and if you are noticing them often it would be a larger infestation. If you are not noticing bites you are more likely dealing with a different type of pest. Here are some photos of carpet beetles If you still aren’t sure please feel free to email us an image and will see if we can help you identify the pest.

    We’ve all had “bed head” but have you heard of “bed bug head”? I apparently got bitten on the head and this caused folliculitis which triggered psoriasis (which I did not know I had) and apparently a happy breeding ground for bed bugs.
    Have you ever heard of anyone getting an infestation of the head? Thank you.

      Hello BedBugHead,

      We have heard of people getting bites on their head, but never heard of them living on people. Bed bugs live in dark secluded areas and usually only come out to feed and return to their hiding spots. If you believe you may have an infestation on your head you should check with your doctor, as it may be another type of pest such as lice.

      Hello Tamora,

      Terminix says: ‘Like many species of bugs, bed bugs release odors called alarm pheromones. When a group of bed bugs gets disturbed, you may be able to smell that odor. Odors may also result from bed bug fecal material. The odor is described many different ways and has been compared to the smell of coriander, an herb. Older publications even refer to the bed bug as the coriander bug. Others describe the smell as “sweet” or “musty.”’ (Reference:

    Last night, I identified bed bugs in my brother’s room, and I JUST sprayed his bed frame down. We are planning to burn it and his mattress as soon as possible. I also have bed bugs at my house (I’m visiting my brother), and I have been fighting them for almost a year (December 2017 is when I started fighting) and I’m planning on burning my bed frame. Do you have any advice that might help us get rid of our infestations? I already know to spray regularly to get the eggs before they hatch.

    Do bed bugs just develope in dry places and why won’t bed bugs just die after a few days of no blood. I bought new mattress covered in plastic, and still had them, why, they must hv been there already…..

      Bed Bugs can live up to five months without a meal and they don’t live only on beds. They can live in any place they can hide. They are attracted to the carbon dioxide that you breath and that is why you find majority of them on and around your bed. If you have any other questions please let us know.
