Bed Bug Pictures

Summary: You have heard a lot about bed bugs and you have probably seen a lot of pictures. Here is a series of bed bug pictures that give you a better sense of their size.  You can learn more about bed bug control products and/or purchase them on this website.


Bed bugs can be found in lots of different shapes and sizes according to their


age and when they last had a blood meal. It is true that bed bugs can be difficult to detect especially when they are in their earliest stages of live. They go through five separate stages called instars. The first, second and even the third instar bed bugs are very small. The picture accompanying this paragraph shows a first stage instar on the forefinger of a male adult. You can barely see it with the naked eye. Put that same immature bed bug on a couch with patterned upholstery and I can guarantee not even the most experienced pest control professional will discover its presence.


Here is a picture of a third instar stage before it has had a blood meal. Although very small, it can still be seen as it is shown sitting next to a penny. This little guy will gorge itself with a blood mean, then go and rest for many days before coming out of hiding and seeking a host for its next feast. This stage, as is the case with all stages, must obtain a blood meal before progressing to its final adult stages.


This is a picture of a full adult bed bug in a person's hand. It is fairly dark in color because it has not had a recent blood meal. As you can see, it is easily visible and about the size of a seed from a medium sized apple. Many people think that bed bugs cannot be seen with the naked eye, but this is graphic proof that bed bugs are not microscopic at the adult stage. Obviously, they are small enough to squeeze into cracks where they can hide from our best most thorough inspections.


This is a picture of a mass of bed bug eggs on a piece of wood. There are several live light colored bed bug nymphs in this picture. All of the dark spots are stains created from the feces of bed bugs. The fecal material consists largely of digested blood. These fecal spots are often smeared on the surfaces on which they are deposited.


After feeding, the bed bug's body is quite distended and almost balloon-like. It is at this point the bed bug moves away from its host and finds a nice, dark spot to rest for several days before emerging again in search of its next meal. At this exact point the bed bug has extracted about seven times its own weight in blood. Talk about gluttony!

I have noticed many red bumps on my chest,neck,face, and in my hair line. I do not know if these are bed bug bites or flea bites. I do have an indoor kitten. These bumps look like some type of bites and have a clear liquid in them. Can you tell me would these be bed bug bites or flea bites?

I have been finding small (apprx. size of small ants), dark bodied insects in my living room. I first noticed these bugs about a month ago as they crawled across white papers on my carpeted floor. I am unsure what type of bug this is- the size has not increased, they only crawl (no jumping or flying), their body shape is similar to a beetle (i.e. head and body are not distinguishable, thus the body does not look divided into sections), there are NO seregated lines on the back (like a bed bug), and no smell. My family members have not noticed any bites, and I have not seen the insects in the bedrooms. Please help me identify this unknown pest. Thank you very much for your time!

Almost exactly like kati's description, I have also seen bugs like that. Each time was on my bed while doing hw they crawled across the white paper of my textbook. Head wasn't distinguishable from the body, had very short legs, and dull spots on the body. Also, each time I saw them was during the day. No bites have been seen. Please help!

Could be carpet beetles, or not. Collect a few in a jar and take them to any local pest control company for a free ID.

Some people say they smell like ripe raspberries, while others think it is a musty odor. Still others claim to smell cilantro. It all depends upon the individual nose.
