Do Spiders Eat Dust Mites? No, They Don’t

Spiders do not eat dust mites. The truth is that spiders don’t eat any types of biting and non-biting mites in your home or outdoors. 

Spiders are nature’s most effective pest controllers. They hunt and eat bugs, ranging from flies to ticks, and roaches, in homes and outdoors.

But dust mites, and all other types of mites, are too small for spiders. Spiders will have to hunt a ton of them to satiate their hunger.

On top of that, the mandibles of spiders are too big to hold those tiny dust mites.

So, if spiders don’t eat dust mites, who eats them?

Let’s find it out.

Who Eats Dust Mites?

Many house bugs can eat these allergy-causing dust mites. But the most common ones are pseudoscorpion, silverfish, ants, and roaches. 

These bugs can eat dust mites and other species of mites like spider mites and clover mites. 

But spiders are natural predators. And spiders help in keeping the bugs population in your home by hunting and eating them.

So does that mean you should leave spiders alone and let them thrive in your home? Well, it’s not as straightforward as it may seem to answer this question.

Let’s find out why.

Spiders are shy creatures. They try their best to avoid human contact. 

The sight of spiders in your home can make you scared. But the truth is that they’re harmless.

Spiders can bite. But they bite if you try to handle them or if they feel threatened by your presence.

Also, female spiders can bite you if you try to damage their egg sacs.

If you leave spiders alone, they’ll remain hidden in the darkest corners of your home and hunt the bugs that infest your house.

But are spiders a solution to professional pest control?

Though spiders can eat hiding bugs in your home, including the tiny bugs like ticks, but they’re not an alternative to professional pest control.

That will lead to many tiny spiders in your home. These little spiders can appear in the unlikeliest places, like your bed and couch.

Spiders won’t help you if your home has termites, bed bugs, ants, and dust mites infestation. 

So, what should you do if you’ve got dust mites in your home? 

Extensive cleaning of your home, washing fabrics and clothes in warm water.

Also, cleaning soft furnishings like bed mattress, carpet, rugs, and couch with a handheld allergen vacuum cleaner removes these allergy-causing dust mites.

You can also use scents that repel dust mites to keep dust mites away from your home. 

What Smells Do Dust Mites Hate?

Dust mites hate the smell of clove, peppermint, eucalyptus, and citrus. 

You can mix the essential oils of these herbs with water and spray them on your beds, curtains, sofas, carpets, closets, and furniture.

That will keep the dust mites from hiding in these places.

However, spiders can also hide in a cluttered bedroom and kitchen, which you frequent often.


Spiders don’t eat dust mites or any types of tiny mites. 

This guide revealed why it is so that dust mite infestation can spike up despite hiding spiders in your home.

But other bugs hide in homes that eat dust mites. Silverfish, pseudoscorpion, and ants are three of them.
