Fleas in Bed: 8 Signs To Look For

Pets are prone to fleas, and you must be vigilant about spotting the signs if you have a pet. Fleas can quickly spread to your bed, couches, hardwood floors, rugs, and other furniture.

Your Pet Is Scratching More Than Usual

One of the most apparent fleas in bed signs is that your pet will start scratching more than usual. This is because the fleas will cause your pet to itch, and the more your pet scratches, the more likely they will develop an infection.

If you suspect your pet has fleas, it’s crucial to take action immediately. In addition to excessive scratching, you may also notice that your pet is losing hair in patches or that their skin is red and irritated.

Fleas can quickly spread through a home. Furthermore, they can also bite humans, so it’s best to nip the problem in the bud as soon as possible. If you are finding fleas in your bed, then there is a good chance that they can crawl through your hair. But can fleas live in human hair? Usually, they do not live in and on human heads.

Bites on Your Body

Flea bites are small and often in clusters. Many people will see these itchy red bumps on their legs since the fleas will jump and bite them from the ground. Fleas are known to jump and crawl, and folks often wonder, “do fleas have wings? and the answer is a resounding “no, fleas do not have wings.”

However, if you have fleas in your bed, you can see these bites anywhere on your exposed skin. Fleas will also bite your pet, so if you notice bites on your pet, it’s a good idea to check for fleas in your bed.

Flea Dirt

Flea dirt is the excrement of fleas, and it looks like tiny black specks. In case you suspect fleas are living in your bed, take a close look at your sheets and pillows for any small black particles.

Remember that the flea specks are not permanent stains like bed bug poop but instead look like pepper flakes.

Check your pet’s fur for flea dirt by combing it with a fine-toothed flea comb. You likely have fleas in your home if you see any black flakes on your pet’s skin or bedding.

Flea Eggs on Your Bed Sheets (Fleas in Bed)

Flea eggs are so small that they will be almost impossible to see with the naked eye. While it’s likely that you have flea eggs on your bed sheets, you are unlikely to see them if you are dealing with a flea infestation.

Each flea egg is 0.5 mm in length. When you compare this to the bed bug egg size of 1 mm, you can see how tiny they are.

To see if you have flea eggs on your bed sheets, use a magnifying glass and look closely at the fabric. If you see any small white dots, these could be flea eggs.

More importantly if unsure, carefully collect these possible flea eggs and use the magnifying glass function on your phone. If your specimen is 0.5 mm, pearly white, and smooth, you may have found a flea egg on your bed sheets.

Wash your bedding in hot water to kill any flea eggs on your bed sheets.

Small Moving Bugs in Your Pets Fur

These are likely fleas if you see small, slender dark colored bugs moving quickly in your pet’s fur. Fleas are about 1.5 mm – 3 mm long and brown or dark in color.

In addition to being small, these bugs can jump up to 19 cm in the air. It is common for fleas to jump from one animal to another, while their eggs, larvae, and pupae can infest your home too.

Mattress Worms (Signs of Fleas in Bed)

The life cycle of a flea involves small worm-like creatures called larvae. These flea larvae (aka: bed worms) will feed on the dried feces of the adult fleas.

Generally, cleaning, washing, vacuuming, and steaming will eliminate flea larvae that might infest your home.

Small Jumping Bug (Fleas in Bed)

You may want to inspect your pet’s fur for fleas if you see a tiny jumping bug. If you use a good flea comb, you’ll be able to determine if your pet has a flea issue.

Another option is to take your animal to the veterinary clinic, and they can do a thorough inspection of your pet’s fur.

If you don’t have pets and see a small jumping bug, you still cannot rule out fleas. One scenario is if you just moved into a new home or apartment and the previous resident had a flea issue. In this case, there is a chance that they left some flea eggs behind, and those have now hatched.

Although vacuuming for fleas is a good idea, you’ll also have to steam your floors to help get rid of any fleas in your home. But keep in mind that the life stages of the flea: larvae, and pupae, are hard to eradicate.

Your Pet is Losing its Fur

Another sign of fleas in your bed is if you notice that your pet is losing its fur. Loss of fur can be due to flea bites or from your pet scratching and biting itself because of the itchiness.

Flea bite dermatitis is a severe allergic reaction to flea saliva, and it can cause your pet to lose its fur. Meanwhile if you see bald spots on your pet or the coat is thinning out, take them to the vet immediately.

What Are the Early Stage Fleas in Bed Signs?

An early stage sign of fleas in your bed is your pet scratching more than usual, you have bites, you see jumping bugs, or you see mattress worms. Any of these signs warrants a closer inspection for fleas.

It’s important to note that some of these signs might indicate a bed bug issue or lice on your bedding.

If you think you have fleas in your bed, the best thing to do is to contact a professional pest control company. They can adequately evaluate the situation and recommend the best course of treatment.

How To Get Rid of Fleas in Bed

Treat the Animals

The first step to getting rid of fleas in a bed is to treat the animals that share the bed with you. You can do treatment with a vet-prescribed medication or over-the-counter flea treatment. If your pets have fleas, you must talk to your veterinarian.

Vacuum the Bed

After you have treated your pets, it is time to focus on the bed itself. The best way to get rid of fleas in a bed is to use a powerful vacuum. 

Vacuum the cracks and crevices around the bed frame and the mattress. Once you have vacuumed, immediately dispose of the bag to prevent fleas from escaping back into your home.

The protocol for fleas is to make sure to dispose of the vacuum bag or contents of the vacuum immediately. 

High Heat Dryer

After you have vacuumed, it is time to put everything through a high-heat dryer. The high heat will kill the various life stages of the flea.


Use a steamer for bed bugs to treat fleas as well. You run the steamer over all of the cracks and crevices in your hardwood floors, which might be a place where the pupae are hiding out.


You may need to hire a professional to treat your home with an insecticide. Hiring a professional is especially true if the fleas have infested other areas of your home, such as the carpet or furniture.

Natural Flea Repellent for Your Perimeter

Use something like Wondercide to treat the outside yard and perimeter of the home. Wondercide is an all-natural, safe product that will help to prevent fleas from entering your home. (and it smells good too)

They even make an indoor Wondercide product; if you treat your pet, vacuum, steam, and high-heat dry everything, you may get away with just using Wondercide instead of heavy pesticides.

Another thing you can do is to plant things that naturally repel fleas. You can use pots or put them straight into the ground.

What Do You Do if Your Dog Has Fleas and Sleeps in Your Bed?

First and foremost, your best action is to talk to your veterinarian and buy some flea treatment for your pet. If you are against using harsh chemicals on your pet, you’ll have to weigh your options because allowing your pet to live with fleas may be just as harmful.

Furthermore your pet may get tapeworms from ingesting fleas, bacterial infections, dermatitis, or flea-borne typhus. The flea-borne typhus is spread between animals and from animals to humans. 

After treating your pet for fleas, you’ll need to follow the steps above to get rid of fleas in your bed.

Final Thoughts for “Help! I Found a Flea in My Bed!”

Fleas in your bed can be a real annoyance, not to mention a potential health hazard. If you find one, there are a few things you can do.

First, try to determine where the flea came from. It likely hitched a ride on you or your pet if it’s just one. In that case, inspecting your pet’s fur and thoroughly checking the bed should take care of things.
