Imagine, pulling down the sheets for a good night’s rest only to discover tiny little worm-like critters in your bed!

While this sounds like the stuff of nightmares (and many who’ve encountered bed worms will say it was), these tiny pests are one of the creepiest things you’ll find hiding in the bed beyond a full-blown bed bug infestation.

Before learning how to get rid of bed worms, it makes sense to first understand what they are.

What Kind of Bed Worms Do I Have?

That said, the term “bed worm” is actually used to describe the larvae of several different pests. The larvae themselves are usually harmless (excluding any potential psychological damage), but their adult forms are another matter.

Let’s give a quick breakdown of some common bed worms and how to deal with each.

1. Carpet Beetle Larvae

Carpet beetles are a common pest, so it’s not unusual for their larvae to end up in your bed or clothing. These are usually carrot-shaped with brown, black, or yellow tones and long hairs. Some also have stripes.

These critters are tiny (between 1/8 and 1/4 inches long), but highly destructive. They love to snack on fabric, feathers, fur, leather, and wool; as well as crumbs and even the corpses of other insects.

Worst of all, they will often migrate from room to room in search of food, often going hungry for long periods of time along the way.

2. Clothes Moth Larvae

Moth larvae love snacking on fabric, especially old clothes that have been put in storage for long periods of time. But that doesn’t mean they won’t pop up on your bed sheets. A few different common moths count as clothes moths.

These little bed worms tend to pop up in similar conditions that attract bed bugs. Their diet includes all sorts of organic debris, including: dust, feathers, fur, hair, leather, lint, and paper.

They don’t care if your sheets are natural or synthetic. Linens which have been stained by body oils, sweat, or spilled drinks are especially attractive to them.

Most clothes moth larvae tend to be a creamy white with a brown head and up to 1/2 inches long. Larvae of the webbing clothes moth leave trails of silk webbing and will line tunnels through your fabrics with silk. Note that some species of moth larvae may have a more brownish appearance.

Obviously, the easiest way to identify your bed worms as moths is to identify a moth infestation. This greatly reduces the chances of mistaking the larvae for that of another critter.

3. Pinworm


Heading into true nightmare territory, we run into the pinworm, which isn’t a larva, but an actual intestinal parasite. Being one of the most common parasites, they most frequently infest school-age children due to how easy it is to spread in a classroom environment.

Pinworms are thin and white, coming in at a mere 1/4 to 1/2 inches. Usually, there aren’t any symptoms of an infection. In fact, the first sign is often spotting a female that slipped out into the bed or your pajamas.

Pinworms live in the anal cavity, and females emerge when the host is sleeping to lay thousands of microscopic eggs in the soft folds around the anal opening. Symptoms include itching around the genital and anal regions, irritability, restlessness, and may even cause stomach pain or nausea.

Because they’re a parasite, you will need to see a doctor and your entire family may need to take antibiotics to eliminate the problem. However, you will also need to treat the bed space in the same way you would for other bed worms.

Getting Rid of Bed Worms

Even though there are different types of bed worms out there, they can all be killed using the same methods. Here are some quick and effective methods to employ against them.

Air Your Dirty Laundry

As with most bed infestations, heat is a quick killer. Run any infested linens through the dryer on high heat to kill any present larvae and eggs. You will then likely want to put them in the wash once the larvae are dead to get rid of the corpses and any feces they left behind.

Vacuum the Bed

Rent a commercial carpet cleaner or purchase a carpet/upholstery cleaner like the Bissell SpotClean if you don’t already have one. These tools are amazing, and can clean carpets and furniture far better than any other common cleaning method out there.

When you use one on your mattress and box spring, it sends hot water deep into the surface, then sucks up dirt, debris, and any critters such as bed worms, bed bugs, dust mites, or fleas. As a result, you not only eliminate part of the infestation, you also have a much healthier sleeping surface.

Investing in a waterproof mattress cover, such as those designed for bed bugs, are easy to clean and make it impossible for future infestations to get into the mattress. With a cover on, you can easily clean the mattress with a warm, damp cloth or regular vacuum cleaner.

Spray Down the Cracks

Small critters like to lay eggs in tiny cracks and crevices. You will want to use a thin pesticide spray or other product to get at these hidden caches.

We suggest mixing essential oils (peppermint and cedarwood work great) in a spray bottle and applying them over cracks, allowing them to soak in. These will usually not harm your surfaces and have a pleasant scent. Some of the places to cover include: baseboard, headboard, bedframe, and cracks in natural flooring.

Just be warned, many essential oils are poisonous to pets, so you will want to wipe the surfaces down afterwards to get rid of any accessible residue.

Eliminate the Host Infestation

Getting rid of bed worms isn’t enough. You will also need to get rid of the adult infestation and any young deposited elsewhere. This is why identifying the bed worms is important.

Once the rest of the infestation has been eliminated, be sure to take steps to reduce the risk of further infestations, such as cleaning regularly, washing bed sheets at least weekly, and closing windows at night if they don’t have screens.

In the event you purchased secondhand furniture and discovered the infestation soon after, there’s a chance you don’t have an adult infestation. In such a case, check nearby just to be sure and perhaps use an insecticide or natural remedy to bug-proof the rest of the room as preemptive pest management.
