8 Signs of Fleas in Bed and How to Get Rid of Them | A Complete Guide

Fleas are known to be parasites of animals, but they can also be nuisance pests in your home, including your bedroom. If you have some fleas in bed, chances are they came from your pet cats or dogs.

Once you ignore them, these fleas will easily accumulate inside your bedroom, and a flea infestation is likely to happen.

So, what are the signs that there are fleas on your bed? Among them are having flea eggs, flea larvae, flea pupae, flea dirt, or adult fleas on your bed. Fleas may also present if there are dark spots on your bed sheets or if your pet dog or cat is scratching frequently and feels uncomfortable while it is on your bed.

Unlike most household pests, fleas bite cats and dogs, but sometimes, even humans. If your pets have fleas and you allow them to sleep on your bed, you are also allowing fleas to be in your bed. In this article, you will learn everything about fleas, including fleas in bed signs and how to get rid of fleas in bed.

What Are Fleas?

What Are Fleas

Scientifically known as Siphonaptera, fleas are blood-sucking parasites of mammals and humans. There are more than 2,200 flea species around the world, and the three common species found in the US are cat flea (Ctenocephalides felis), dog flea (Ctenocephalides canis), and the human flea (Pulex irritans).

Fleas go through a complete metamorphosis, which means they undergo four life stages – egg, larval, pupal, and adult stages.

Under ideal conditions, fleas may complete their entire life cycle between 20 and 35 days. Fleas can reproduce any time of the year indoors and only in warmer months when they are outdoors.

What Do Fleas Look Like?

What Do Fleas Look Like

At the naked eye, fleas look like bed bugs since both of them are reddish-brown, wingless, and have six legs.

But unlike bed bugs, fleas have rounded and longer bodies instead of oval bodies. Fleas also have longer hind legs, making them capable of jumping as far as 13 inches or about 200 times their body length.

Signs of Fleas in Bed 

Signs of Fleas in Bed

As mentioned earlier, fleas love animals, and they suck their blood. But once their favorite diet is not available, they may also bite humans.

Fleas don’t usually jump from one host to another, but they can leap or fall on your bed if your infected pet scratches them away. With that, below are the common signs of fleas in bed.

1. Flea Eggs on Bed Sheets

Flea eggs are white, about 1/50 inch (0.5 mm) long, and smaller than a grain of sand.

These oval eggs may be very small to see with naked eyes, but they can accumulate on your bed sheets. Females usually lay 4-8 eggs at a time and can lay up to 500 eggs in their lifetime. These eggs can turn into larvae in 2-4 days.

2. Flea Larvae on Bed Sheets

Flea larvae are white, legless, and about 3/16 inches (4.8 mm) long. These worm-like larvae have brown heads and chewing mouthparts, which allows them to feed on dried blood.

Once they are full, their bodies will turn almost purple. Mature flea larvae can quickly crawl in floors, carpets, and even bed sheets.

3. Flea Dirt on Bed Sheets

Flea dirt (or flea feces) is usually black or dark reddish-brown and can be found in pets and their beddings. These pepper-like dried blood are very nutritious for flea larvae and help them a lot in becoming adults.

Unlike bed bug feces, flea dirt leaves a red stain on bed sheets if you wipe it with a wet paper towel or cloth.

4. Pet in Bed Scratching Frequently 

Every time fleas feed on your pet, they discharge saliva that can cause allergy and itchiness on the skin. Once your dog or cat is being attacked by flea bites, they cannot help but scratch their skin frequently.

Sometimes, infected animals also bite their skin. If your pet is on your bed, fleas may fall on the bed sheet.

5. Flea Bites on Pets and Humans

Fleas prefer biting animals over humans, but it does not necessarily mean that they will not bite you. Flea bites on animals can leave a hard, small, red swollen mark on the skin.

Allergic and young animals such as kittens and puppies may suffer from dermatitis and anemia and may die if not treated immediately.

Fleas rarely bite people, but when they do, these ectoparasites attack most often on the legs and ankles. Flea bites on humans seldom cause swelling of skin unless the bite is scratched and the skin is sensitive.

Instead, they leave a single small red spot with a light color at the center caused by the flea’s mouthparts. 

6. Dark Spots on Bed Sheets 

If you see specks or dark spots on your bed sheets, they could be due to flea eggs or dead fleas, especially if your pets are always on your bed.

Unlike bed bugs that crawl quickly after biting, fleas tend to stay on their host or near their food. This is why you might have accidentally killed them while you are sleeping.

7. Flea Pupae on Bed

Flea pupae are also white, and they live in cocoons, which the larvae made by spinning silk. These cocoons serve as the flea’s protective covering while they are molting and growing into adults.

The pupal stage is completed within a week, but adult fleas can still survive in cocoons for 5 months while waiting for a host. 

8. Live, Adult Fleas in Bed

If you find a single flea on your bed sheet, it might not be a cause for alarm, especially if your pet does not sleep on your bed.

But if there are already two or more live adult fleas in bed, it is very likely that your pet is already suffering from flea infestation, whether your pet cat or dog sleeps on your bed or not.

Can You Have Fleas in Bed Even If You Don’t Have Pets?

Can You Have Fleas in Bed Even If You Don’t Have Pets

You can still have fleas on your bed even if you don’t have a pet dog or cat. Wildlife like opossums, raccoons, skunks, and squirrels can also have fleas before they enter your attic or chimney.

You may have removed these wild animals out of your house, but fleas can be left behind and crawled into your bed.

How to Get Rid of Fleas Out of Bed and Pets?

Fleas are not only nuisance pests at home. Most of them may also be carrying pathogens that can cause fleaborne diseases such as plague and murine typhus.

This is why you should get rid of them as soon as possible. To help you, here are some effective ways on how to kill fleas in bed and on your pet cats and dogs.

1. Vacuum your bed sheet thoroughly. You might also want to vacuum the areas where your pets rest and sleep. Seal the used vacuum bags and throw them away.

2. If possible, vacuum every corner of your house, including furniture and edges of each room.

3. Wash bed sheets, blankets, and pet beddings using hot water and detergent. Fleas may not die if the water is below 95°F (35°C).

4. Spot clean your mattresses. Garment steamers such as Electrolux Portable Handheld Garment & Fabric Steamer not only kill fleas but bed bugs, too.

5. To kill flea eggs and larvae, use an insect growth regulator (IGR) such as ZOECON Gentrol Insect Growth Regulator . Note, however, that these products don’t kill adult fleas. For best results, mix it with a mild insecticide.

6. Give your pets a good bath and use a flea comb such as Safari Dog Flea Comb with Double Row of Teeth .

7. For adult pets, try using pet collars such as Hartz UltraGuard Flea & Tick Collar . Most of these products are water-resistant and are effective for 7 months.

8. Apply a topical spot-on treatment to your pets, depending on the product label. Among the popular brands of such products are Frontline®  and Advantage II® .

9. Feed your pets with oral medication or chewable tablets. Products such as Capstar Fast-Acting Oral Flea Treatment for Dogs  kill fleas within hours after ingestion.

Note: Some pet products are suitable for dogs only but not for cats. Make sure you use the right product and the correct dosage, as per product instruction. For the safety of your beloved pets, consult a veterinarian before using any product.
