Bed bugs are notorious pests that can quickly infest your home and disrupt your peace of mind. These tiny creatures are difficult to spot, and you may not even realize you have a bed bug infestation until it has become a significant problem. Therefore, it’s essential to know what signs to look for to identify bed bugs as early as possible. In this article, we will discuss the signs bed bugs leave behind and how you can prevent and manage their infestations.


Yes, This is because they’re not enough small to become invisible and they need to walk around to reach anywhere.


As I told you before, you can see them with the naked eye. So, you can ask this question: If I can see them, then why should I go after signs?

There are 2 main reasons for this:

Because of this in most cases, when you get up in the morning, you have a lot of red itchy bite points on your body which you have no idea about where they came from. This is the time to search for its reason.


In many cases, it’s not true to limit signs of any possible bugs at home. They can occur in many ways. But these are common signs of bed bugs:

  • Black feces everywhere
  • Blood stains around
  • Shed skins
  • Smell of them
  • Tiny eggs
  • Bites on your body

I know some of these signs aren’t so clear, but let me take a close look at these signs.


Do bed bugs have feces? Yes, they do just like other bugs. After a bed bug is fed enough, it will drop feces around.

This bed bug feces will become partially digested blood. When bed bugs drop feces, it will be red and after a while, it will get darker.

Feces will usually be near their nest. You test those feces you found by spraying hydrogen peroxide on it or even water and if it turns a rust red color, that means it’s feces.


Because bed bugs feed by sucking blood, it’s very normal to see blood stains around. But how are those blood stains?

Blood stains that bed bugs leave behind are small and a lot of those stains will usually be together. If bed bugs feed on you while you are sleeping, then you will see blood stains on your mattress or pillow.



Bedbugs do shed their exoskeleton. Their shed skins will be almost the same as a live bed bug. Of course, this shed body will be empty and it can’t move around.

Bed bugs will molt until they become an adult. Before they become adults, they have 2 other stages in their lives: Egg and nymph.

Once a bed bug becomes an adult, then it won’t molt anymore. This means that if you find shed bed-bug skins around, you might have a bed bug infestation in your house.


However, bed bugs have a specific smell, most people define that smell differently from each other. People define it as irony, musty, woody, or something else.


Bed bugs multiply by laying. Bed bug eggs are yellow-white. They stand together and are glued to the surface, usually in cracks. The most distinguishing feature of those eggs from the other bug eggs is “glue”:


The natural result of having bed bugs is to be bitten by them. Because bed bugs are blood-fed creatures and they will be after you for feeding by sucking your blood.

Bed bug bites will not hurt you just while you’re bitten because of a chemical they secrete into your blood:

So, when you get up in the morning and realize some red itchy bites on your body, that will be the biggest sign that you have.

Behavioral signs of bed bugs

Apart from physical signs, bed bugs also leave behind behavioral signs that can indicate their presence. These include:

Musty odor

Bed bugs release pheromones that give off a musty odor. If you notice an unusual, sweet, or musty odor in your bedroom, it’s time to inspect for bed bugs.

Visible bed bug skins and eggs

As bed bugs grow and molt, they shed their skins and leave behind their eggshells. These skins and eggs are tiny and hard to spot, but if you inspect your bedding materials, you may find them.

Bed bug trails and nests

If you have a severe bed bug infestation, you may notice bed bug trails and nests around your home. These trails may appear as dark, rusty spots along baseboards, walls, and ceilings. Bed bug nests may also be found in crevices and cracks in your furniture, walls, and flooring.

Common misconceptions about bed bugs

There are many common misconceptions about bed bugs that can make it difficult to identify and manage their infestations. Some of these misconceptions include:

Bed bugs only infest dirty environments

Bed bugs do not discriminate based on cleanliness. They can infest any home, regardless of its level of cleanliness

Bed bugs only bite at night

While bed bugs are nocturnal and are more active at night, they can still bite during the day. Therefore, it’s essential to be vigilant and check for bed bugs at any time of the day.

Bed bug infestations are easily treated

Bed bug infestations are challenging to treat and may require multiple treatments to eliminate them. DIY treatments are often ineffective and can even make the infestation worse.



You must remember that when you once have bed bugs at home and have a treatment, even if you can’t see any signs of them and you will still be paranoid about their existence.

Because in some cases, bed bugs will be still there even if they don’t move anywhere but their nest. They are tough creatures and they can prefer to keep hiding until they have to feed again.

Here are some comments about bed bugs signs made by real people on social media so, you can understand better how to approach this issue:

“Every time I lay in my bed, I get bitten. No signs of bb. I have sprayed, bombed, boric acid, used vinegar, and exterminated. I am still getting bitten. Any suggestions as to what it could be? Remedies?”

“I am super paranoid and think I am still getting bit. They disappear faster than bb bites though. I haven’t seen anything in over a month and I do look.”

“We had an inspector come out and tell us he sees no signs of bugs…. I have 5 new bites that popped up after we threw our headboard out and washed everything. And some black markings on the bedding that weren’t there before. He said we could move forward with treatment if we want to.”

“My last treatment was 3 weeks ago. We did a DIY chemical treatment 3 times for safe measures. There have been no signs of any bed bugs on the beds or furniture. There have been no more bites to anyone. We added interceptors to the beds. Nothing in them. What else should I do to keep monitoring for signs?”

“I did everything I was told, no signs of anything but for some reason, I itch or feel like something is crawling on me but when I’m not home I feel nothing. I thought it might be that d earth stuff but I’ve cleaned up most of it. So why am I feeling tickle spots or itches?”
