What could be more horrific than pulling down your sheets in the middle of the night and finding tiny little worm-like critters in your bed? If you have seen a few already, you are not alone. Bed worms are common worldwide and don’t cause much harm except discomfort and terror that can rob you of good night’s sleep. Many people tend to confuse bed worms with bed bugs worms.

Bed worm is a term used extensively to describe the larvae of different pests. In most cases, the larvae are usually harmless, but when they emerge as adults, they are a different story. Also, just because they are called bed worms does not mean they can only be found on beds. In this article, we will discuss what bed worms really are, the different types, their cause, how they spread, and how to get rid of them.

What Are Bed Worms?

As mentioned before, most bed worms are the larvae of other insects, including moths and carpet beetles, and they can be found in other places other than the bed. The bed worms mostly end up in your bed to eat the beddings as they feed on natural fabric like silk and wool. Although they are frightening, bed worms are completely harmless unless you have an allergic reaction to their bite.

Types of Bed Worms

How to Get Rid of Bed Worms: Your Complete Guide

Here is a quick rundown of the most common types of bed worms you are likely to encounter on your bed.


These tiny white parasitic worms take the crown for creepiness. They crawl out of the anus to lay eggs and breed on the bed while you are asleep. You can identify them as white pinpricks or thin threads. According to the Centers for Disease Control and Prevention (CDC), Pinworms’ excretion is harmful and can lead to itching around the waistline or, worst cases, muscle pain from inflammation.

Carpet Beetle Larvae

These are tiny moths commonly found in bed or clothing. They have long hair and come in either brown, black, or yellow tones with stripes on their body for easy camouflaging on the fabric they love to feed on. Carpet beetle larvae look alike, making it hard to tell the species apart.

Flea Larvae

Your pets can transfer fleas to your bed if you hang with them in bed. When the adult fleas drop on the bed, they will find refuge in the tiny gaps and cracks on the mattress and bed frame. If your pets don’t come around often, the fleas will bite you to feed and keep reproducing. The female adults will lay eggs from which the larvae would emerge. Although hard to spot, flea worms are also bed worms.

Clothes Moth Larvae

These love to eat fabric and can eat anything, from the old clothes stored away in your wardrobe to the upholstery on furniture. Good thing is clothes moth larvae will always leave a clear clue that they are around. The larvae are about ½ inch long and have a creamy or white body with a brown head. They leave silk webbing trails and line tunnels through your clothes with silk.

Life Cycle of Bed Worms

As bed worms can be the larvae of any insect or pest, the life cycle may vary. Although most insects have a life cycle with four stages, egg, larva, pupa, and adult, they bear different appearances and characteristics in the different stages.

For instance, the egg of a flea worm will not have the same appearance as the egg of a carpet beetle larva or cloth moth larvae. You can identify a bed worm’s eggs by looking for round or oval-shaped substances that appear in clusters on your sheets. In the larvae stage, you will see the worm, and in the pupa stage, you will see cocoons or dark, hard shells. In the adult stage, you should be able to look up the insect continuing its lineage in your beddings.

Why Do They Appear?

How to Get Rid of Bed Worms: Your Complete Guide

Bed worms can appear in your home for various reasons, including:

  1. Dirty living conditions

Most bed worms creep into beds for food. Dirt and food stains are the main diet for the majority of bed worms. If you eat and leave food crumbs and stains in your bedding, you will likely attract bed worms, especially the carpet beetle larvae and the clothes moth larvae. The larvae will chew on the stained areas in your bedding, and it can be worse if they are of high quality and made of top-notch products like silk.

The worms will be attracted to other furnishings in your house, like carpets, upholstery, and curtains, if they are dirty.

  1. Damp spaces

Besides dirt and food stains, dampness, especially in the kitchen and bathrooms, can cause bed worms. The larvae of kitchen pests thrive and develop in food waste, high wetness, and organic waste. These larvae can also creep into your bed if you leave food stains on your bedding. Damp bathrooms also provide a suitable environment for insect breeding. The larvae of these insects can crawl into your bed, especially if you are fond of visiting the bathroom at night.

  1. Open windows and doors, cracks, and crevices on walls

Bed worm-causing insects can enter your house when you open the windows or doors or through any openings on the walls. You can also bring the insects yourself unknowingly. For instance, you can bring adult carpet beetles into your home with the potted plants you buy from a plant store.

How Do They Spread?

Bed worms don’t necessarily originate from the bed. Most bed worms hitch a ride to your bed on your clothing or pet’s body. They can also crawl from one point to another. For instance, if there are insects developing in your damp bathroom and it is adjacent to your bedroom, the worms can easily crawl to your bed.

Are Bed Worms Harmful to People?

Bed worms are not harmful to humans. Insects are harmless in their larval stage. However, they are a frightening sight that can rob you of a good night sleep.

You will know for sure you have bed works if:

  • You see small round or oval shaped eggs in clusters on your bedding or furniture.
  • You find small, dark stains on your bedding and furniture
  • You see small insect-like dots crawling on your bedding or furniture

You should act immediately upon seeing these signs to prevent further spreading and an uncontrollable population.

With the chemical option, you will be spoilt for choice as there is an extensive range of chemical products to choose from. Go with a pesticide made specifically for killing bed worms and their eggs. Here are a few examples:

Insecticides Made with Pyrethrin

The National Pesticide Information Center defines Pyrethrins as pesticides derived from Chrysanthemum flowers on their fact sheet. Their natural compounds are used to make insecticides that can kill various insects including bed worms. Most pyrethrin-based insecticides are safe to use around children and pets.

The insecticides come in concentrated liquid or aerosol form. Either option would work well for managing bed worms in your home.


These are insecticides that work by paralyzing insects’ nervous system. Most of them are fast acting with long-lasting residual control and can kill insects in all their development stages, including eggs, larvae, pupa, and adults. You can get one that comes in a ready-to-use aerosol form and doesn’t leave residue to spray on your bedding and furniture infested with bed worms.


Permethrin is a synthetic insecticide that kills insects by paralyzing their nervous system just like Neonicotinoids. You can use it on bedding, furniture, carpets to kill bed worms and in the outdoors to control other pesky insects like fleas and ticks.

How to Get Rid of Bed Worms Step by Step

After establishing that you have a bed worm issue, you need to act quickly to prevent further spreading and damage on your clothing items. According to a Science research paper about the life cycle of insects, the larval stage causes the most damage as most insects develop chewing mouthparts at this stage.

Here is a step-by-step guideline on what to do to get rid of the worms completely:

Step 1: Declutter

As mentioned before, bed worms thrive in dirty and cluttered spaces that offer adequate hiding. Before doing anything, remove all the unnecessary clutter in your home. Part with clothes, shoes and other belongings that you don’t need. After decluttering, clean your storage spaces like cabinets, closets and drawers.

Step 2: Remove Your Bedding

The first thing to do is remove your bed sheets or bed cover from your bed then throw them in the washer and dry them at high heat in the dryer. You can also air dry under direct sunlight. Bed worms cannot withstand high temperatures, therefore the more you subject your infested bedding to high temperatures, the higher the chances of killing all the bed worms. Ensure you wash and dry all the soft items you have around your bed like pillows, rugs, and pet beds.

You can seek the help of professional cleaners to help you get rid of bed worms. Their large commercial-grade equipment is likely to clear most of the bed worms.

Step 3: Vacuum Your Bed and Furniture

Regular vacuuming is an essential exercise when ridding your home of bed worms. Vacuum your bed’s surroundings thoroughly, from the floor to the ceiling to get any food crumbs or stains out of the way. Move all your furniture and vacuum all the spaces to ensure you leave nothing that attracts bed worms. When done, clean all the hard surfaces with a damp cloth.

You can invest is Bissel cleaners which work by directing hot water into the deep unreachable areas of the bed and other furniture to suck out all the bed worms and other insects. The cleaners also suck other things like debris and dirt. Once you are done cleaning, invest in a high-quality waterproof mattress cover that will allow you to clean the mattress easily with a regular vacuum cleaner or warm, damp cloth. What’s more, it will prevent tiny critters from entering your mattress next time.

Step 4: Spray Down All the Cracks and Crevices with a Pesticide

How to Get Rid of Bed Worms: Your Complete Guide

Insects live and lay eggs in tiny cracks and holes. Get a thin pesticide spray that can penetrate the tight hideouts and spray all of them down. Spray the headboard, baseboard, bed frames and all the cracks on the bed. If you need a spray and have no idea what or where to get one, consider the popular Reefer-Galler SLA Cedar Scented Spray. It can kill the eggs, larvae and adult clothes moths and carpet beetles. It is also a fantastic repellent spray against other pests like flies, roaches, moths and mosquitoes. Its fresh cedar scent will leave your space freshened up.

You can also mix essential oils like peppermint and cedarwood if you can’t access a pesticide spray. The mixture would be just as effective and won’t damage your wall or furniture surfaces. Plus, you will enjoy the sweet scent the essential oils have.

After treating the cracks and crevices, seal them to prevent future infestations. Fill the spaces around the doors, window frames, headboard and baseboard with spray foam insulation. You can also use mastic caulking to fill the cracks around your bed.

Step 5: Dry Clean Your Clothes

As mentioned before, carpet beetle larvae and clothes moth larvae thrive on certain types of fabric including, fur, leather, and wool. If you are seeing them creeping on your bed, it is highly likely they are in your closet as well. Remove all of your clothes and dry clean them. Dry cleaning will expose the worms to high temperatures and kill them immediately.

Ensure you vacuum your closets and drawers or wherever you store your clothes before arranging them after dry cleaning. Otherwise, they would get re-infested by the few bed worms still hiding in the corners and cracks.

Step 6: Wash Your Pets and Their Bedding

Pets are good carriers of almost all kinds of bugs. Once you have cleaned your house thoroughly, give them a good bath with a good shampoo that can kill all the bugs on them. Clean their bedding in high heat as well and aerate them. Invest in several pet bedding so you can change them regularly for cleaning.

Step 8: Get Rid of All the Host Infestation

To get rid of all the bed worms in your home you have to thoroughly clean or eliminate all the items harboring them like clothes, bedding, furniture, and mattresses. If there are infested items that you cannot clean or treat to remove all the bed worms, you have no choice but to do away with them.

After eliminating all the host infestation and all the external threats, ensure you clean regularly, wash your bedding at least once a week, and close the windows at night to minimize the risk of another infestation.

Step 9: Call a Pest Control Professional

If you follow all the steps above and you still see signs of bed worms, you can call for help from a pest control professional. They will do a thorough inspection and if they find any bed worms, will eliminate them professionally. You will also benefit from their tips on preventing a future infestation.

How to Prevent Bed Worms Infestation

Although insect larvae are harmless, you can’t be too sure about what the bed worms in your bed will grow into. They may grow into insects that can pose serious threats to your home and your well-being. Therefore, if you have just cleared an infestation you should work to prevent the risk of a future one occurring.

Vacuum Regularly

Ensure you vacuum your bedroom and entire house as often as possible to remove dirt and any food crumbs or stain that could attract bed worms. You can invest in a handheld mattress vacuum to suck out all the dirt and micro-organisms from your mattress.

Change Your Bedding Regularly

Remove your bed sheets and bed cover at least once a week for cleaning. Clothes moth larvae and carpet beetle larvae love to feed wools and linens. Washing your beddings in hot water and dry cleaning your clothes can keep bed worms at bay significantly.

Seal All the Cracks and Crevices

Sealing all the openings through which insects causing bed worms can enter is crucial. Make a habit of closing the windows at night to prevent creepy bugs from entering.

Keep the Kitchen and Bathroom Clean and Dry

A dump kitchen or bathroom is one of the main causes of bed worms. Ensure your bathroom floor is dry after showering and make a point of cleaning it with a disinfectant routinely to prevent the development of bugs. As for your kitchen, keep it clean and take out the trash routinely.

Use an Air Conditioner and an Insect Repellent

An air conditioner will regulate the temperatures in your home and keep away insects during warm and dry seasons. According to an article by K-State Research and Extension, flying insects hate cold temperatures. Therefore, you can set your AC low when you leave the house during the day to keep the insects away. An insect repellent will do the same. If all insects are outside, nothing would be laying eggs that hatch into larvae/worms in your bed.
