How to eliminate mattress mites? - briefly
Regularly vacuum the mattress, wash all bedding at ≥60 °C, and encase the mattress in a zippered, allergen‑proof cover. Keep humidity below 50 % and apply an approved acaricide or diatomaceous earth to the surface.
How to eliminate mattress mites? - in detail
Dust mites thrive in warm, humid environments and feed on dead skin cells that accumulate in bedding. Their presence can trigger allergic reactions, asthma attacks, and skin irritation, making effective control essential for a healthy sleeping area.
The first step in control is to reduce the food source. Wash all bedding, including sheets, pillowcases, blankets, and mattress covers, in water heated to at least 60 °C (140 °F) for 20 minutes. This temperature kills both adult mites and their eggs. If hot water is unavailable, add a cup of white vinegar to the wash cycle; the acidity lowers the pH, creating an inhospitable environment for the insects.
Next, address the habitat. Maintain indoor relative humidity below 50 % by using a dehumidifier or air conditioner, especially in the bedroom. Low humidity slows mite reproduction and shortens their lifespan. After cleaning, expose the mattress to direct sunlight for several hours; ultraviolet radiation and heat further reduce mite populations.
Vacuum the mattress surface and surrounding area with a HEPA‑filtered vacuum cleaner. Use a brush attachment to dislodge mites from seams and crevices, then empty the vacuum bag or canister into a sealed bag and discard it outside the home. Repeat this process weekly during peak mite season (spring and summer).
Encasements designed specifically for dust‑mite protection create a physical barrier that prevents mites from entering or escaping the mattress and pillows. Choose zippered covers with a pore size of 10 µm or smaller, and keep them on continuously.
For chemical control, apply an acaricide approved for indoor use according to the manufacturer’s instructions. Spray the product evenly on the mattress surface, allowing it to dry completely before re‑covering the bed. Limit repeated applications to avoid residue buildup.
Natural alternatives include:
- Sprinkling a thin layer of diatomaceous earth on the mattress, leaving it for 24 hours, then vacuuming thoroughly. The abrasive particles damage mite exoskeletons.
- Using a few drops of tea tree oil or eucalyptus oil diluted in water as a spray. Both oils possess insecticidal properties; apply lightly to avoid staining.
Finally, establish a maintenance routine: wash bedding weekly, vacuum the mattress monthly, and monitor humidity levels regularly. Consistent application of these measures significantly reduces mite populations and minimizes associated health risks.
