How to Get Rid of Dust Mites in Your Mattress: The Complete Guide

Dust mites are microscopic creatures that live in mattresses, pillows, and bedding — feeding on dead skin cells and thriving in warm, humid environments. You can't see them, but their waste products are a leading cause of indoor allergies and asthma. This guide covers how to eliminate dust mites from your mattress and prevent them from returning.

What You'll Need

• The Ecology Works Dust Mite Allergy Spray — plant-based formula that denatures dust mite allergen proteins in bedding and mattresses; fragrance-free and safe for all fabrics
• Pressurized Handheld Steam Cleaner — high-temperature steam kills dust mites on contact
• Nutricost Baking Soda (2 lbs) — deodorizes and helps create an inhospitable environment for dust mites
• PlushDeluxe Waterproof Bamboo Mattress Protector — creates a physical barrier that prevents dust mites from colonizing the mattress
• AllerEase Pillow Protectors (Set of 2) — zippered allergy protection for pillows
• Shark Navigator HEPA Vacuum — HEPA filtration captures dust mite allergens rather than recirculating them

Understanding Dust Mites

• Dust mites are 0.2–0.3mm — invisible to the naked eye
• A single mattress can harbor 100,000 to 10 million dust mites
• They thrive in temperatures of 68–77°F and humidity above 50%
• It's not the mites themselves but their waste proteins (Der p1) that trigger allergies
• Symptoms: sneezing, runny nose, itchy eyes, congestion, and worsened asthma — especially in the morning

Step 1: Vacuum with a HEPA Vacuum

Use the Shark Navigator HEPA Vacuum with the upholstery attachment to vacuum the entire mattress surface slowly and thoroughly. HEPA filtration is critical — standard vacuums can recirculate dust mite allergens back into the air. Make multiple slow passes, paying extra attention to seams and edges.

Step 2: Steam Clean the Mattress

The handheld steam cleaner kills dust mites on contact with temperatures above 130°F. Move slowly across the entire mattress surface in overlapping rows, holding the steamer 1–2 inches from the surface. Pay extra attention to seams and edges where mites concentrate. Steam both sides of the mattress.

Step 3: Apply Dust Mite Allergen Spray

After the mattress has dried from steaming, spray The Ecology Works Dust Mite Allergy Spray over the entire mattress surface. This plant-based formula doesn't kill mites but denatures (neutralizes) the allergen proteins in their waste — eliminating the allergic response even from mites that remain. Allow to dry before making the bed.

Step 4: Deodorize with Baking Soda

Sprinkle baking soda over the mattress, let sit 30 minutes to several hours, then vacuum thoroughly. Baking soda helps absorb moisture that dust mites need to survive.

Step 5: Protect with Allergen Barriers

After cleaning, install protective covers:

• Put the PlushDeluxe Waterproof Mattress Protector on the mattress — the tightly woven fabric creates a physical barrier that dust mites cannot penetrate
• Put AllerEase Pillow Protectors on all pillows — pillows are a major dust mite habitat

Ongoing Prevention

• Wash bedding weekly in hot water (130°F+) — this kills dust mites in sheets and pillowcases
• Reduce bedroom humidity below 50% with a dehumidifier — dust mites cannot survive in low humidity
• Vacuum the mattress monthly with a HEPA vacuum
• Steam clean every 3–6 months
• Keep bedroom temperature cooler — dust mites prefer warmth
• Minimize soft furnishings in the bedroom — rugs, curtains, and stuffed animals are additional mite habitats

Frequently Asked Questions

Can I feel dust mites biting me?

Dust mites don't bite — they're too small and don't feed on living humans. The itching and irritation associated with dust mites is an allergic reaction to their waste proteins, not bites.

Does freezing kill dust mites?

Placing small items (stuffed animals, pillows) in a sealed bag in the freezer for 24–48 hours kills dust mites. However, freezing doesn't remove the allergen proteins from their waste — you still need to wash or vacuum the item afterward to remove the dead mites and their waste.

How long does it take to reduce dust mite allergies after cleaning?

Allergy symptoms typically improve within a few days to weeks of implementing a thorough dust mite control routine. The allergen proteins can persist in the environment for months after mites are eliminated, so consistent cleaning and allergen barrier covers are important for sustained relief.
