How to combat dust mites at home? - briefly
Lower indoor humidity below 50 % with a dehumidifier, vacuum weekly using a HEPA‑filtered machine, and wash all bedding at ≥60 °C. Encase mattresses and pillows in allergen‑proof covers and remove or replace carpet and upholstered furniture that can harbor mites.
How to combat dust mites at home? - in detail
Dust mites thrive in environments where humidity, temperature, and food sources—primarily human skin flakes—are abundant. Reducing these conditions limits their population and prevents allergic reactions.
- Wash all bedding, pillowcases, and blankets weekly in water heated to at least 130 °F (54 °C). Use a dryer on high heat for a minimum of 15 minutes if washing at lower temperatures.
- Encase mattresses, box springs, and pillows in zippered covers certified as dust‑mite‑proof. Replace covers annually or when they show wear.
- Vacuum carpets, rugs, and upholstered furniture with a HEPA‑rated filter at least once a week. Follow with a steam‑cleaning cycle when possible; the heat destroys mites and their eggs.
- Maintain indoor relative humidity below 50 %. Deploy dehumidifiers in damp areas such as basements and bathrooms, and use a hygrometer to monitor levels.
- Remove or limit wall‑to‑wall carpeting, especially in bedrooms. Opt for hard‑surface flooring (tile, wood, laminate) that can be mopped with a damp cloth.
- Clean curtains, drapes, and blinds regularly. Wash removable fabrics in hot water; for non‑washable items, vacuum with an attachment designed for delicate fabrics.
- Eliminate clutter that accumulates dust, including piles of magazines, books, and stuffed toys. Store infrequently used items in sealed plastic containers.
- Apply acaricidal sprays or powders labeled for indoor use on areas where dust mites are likely to hide, following manufacturer instructions precisely.
- Replace air filters in HVAC systems every three months and consider installing an air purifier equipped with a HEPA filter in bedrooms to capture airborne allergens.
Consistent application of these measures creates an environment hostile to dust mites, significantly reducing their numbers and the associated health risks.
