Here are seven indications that dust mites may be present in your mattress — and why their presence can adversely affect your sleep



How to tell if you have dust mites in your mattress and how to get rid of them

Dust mites are microscopic pests that dwell in four out of five homes in America, and even the best mattresses with the latest hypoallergenic technologies aren’t immune to their presence. As their name suggests, dust mites lurk in the hidden dusty spots within our homes, where they’re free to feast on our dead, shed skin.

If you haven’t hoovered under your bed or washed your sheets in a little while, there’s a strong chance that you have mites feeding and breeding there. They can’t be seen with the naked eye, but there are telltale signs of their presence.

“If you notice you’re itching uncontrollably despite having no bite marks, it’s more than likely you’re sharing a bed with a horde of dust mites,” says Rebecca Swain, mattress expert at Winstons Beds. “While you can’t see the critters without using a microscope, their presence can be known if you’re suffering from a dry cough in the morning and itchy eyes.”

What’s more, dust mites can aggravate allergies and disrupt your sleep, so here’s how to spot them.


1. Your sleep is disrupted
According to the American Lung Association, dust mites can aggravate existing allergies and cause respiratory issues, such as asthma. This can lead to breathing difficulties as well as symptoms that closely resemble a common cold, such as swollen nasal cavities or a runny nose. This can make it difficult to fall and stay asleep, as well as cause snoring. Pay attention to your symptoms—are they more pronounced during the night? Dust mites can impact your sleep quality, so it’s important to keep your bed clean and their numbers down.

2. You have a dry cough
A dry, lingering cough is a strong indication that dust mites could be making a nest in your mattress and bedding, especially if your cough is dry but your bedroom is humid. Dust mites don’t drink water and instead rely on the moisture that we lose through our pores while we sleep, which can be anything between 0.5 and 1 liter per night. If you’re waking up with a sore throat and a dry, itchy cough, it’s a strong indicator that the bed is infested with dust mites.

3. You have itchy skin
Dry, itchy skin is another sign that dust mites are dwelling in the soft furnishings within your bed. The critters feed on dead skin cells in the bed, which is why it’s important to regularly wash bedding on a 60ºC cycle to prevent an infestation. Dust mites can’t live without moisture in the air or the soft furnishing that they burrow within. Don’t make your bed in the morning, and leave a window open to disperse that moisture and keep humidity levels down.

4. Bedtime makes you sneeze

A dust mite allergy resembles hay fever or a cold, so sneezing is common when dust mites are present, especially if your sneezing is more pronounced at night. Sleeping in an area of the bed that is infested with critters can stir up allergies and cause sneezing and runny noses, so don’t ignore those symptoms. It can be difficult to differentiate between a common cold and a dust mite allergy, but if your cold-like symptoms persist after a week, it could be a dust mite allergy.


5. It’s difficult to breathe at night
The presence of dust mites is one of the biggest indoor triggers for asthma, which can cause both mild and severe symptoms, including an asthma attack. This is because the allergens caused by dust mites (or rather, their feces) can cause your chest to tighten, making it difficult to breathe during the night.

Difficulty breathing or wheezing should never be ignored, especially if you have an existing respiratory issue. Make sure to thoroughly vacuum your mattress and bedroom to remove the dust mites, their feces, and any excess dust particles. If the issue persists, seek the advice of a doctor.

6. You have dry, itchy eyes
Unlike bed bugs, dust mites don’t bite or sting. Instead, they make their presence known by causing flu-like symptoms that make our eyes water and itch when we come near them. If you often wake up with itchy eyes, a dust-mite infestation could be to blame.

7. There are visible signs of dust
Dust bunnies is a cutesy term for what could potentially be a colony of dust mites lurking in and around your bed. Dust mites spawn in soft furnishings, such as curtains, bedding, and—if you don’t have a mattress protector—deep within your mattress. They feed on shed human skin cells and moisture in the air. If you can see dust, there’s a high chance that dust mites are present, even if you’re lucky enough not to suffer from any of the above symptoms.

How to get rid of dust mites
Dust mites thrive in dark, humid environments where they can survive on shed skin cells and moisture trapped in soft furnishings. You can drastically reduce the number of dust mites dwelling in and around your bed by regularly cleaning your sheets and washing them at 60 degrees, vacuuming your mattress, and investing in a hypoallergenic mattress protector to keep moisture locked out of your mattress. Remember, dust mites love humidity, so open the window wide and allow plenty of airflow through your bedroom, too.
