How to kill mites in pillows? - briefly
Launder pillows at ≥ 60 °C, dry on high heat, encase them in allergen‑proof covers, and periodically vacuum or apply a safe acaricide.
How to kill mites in pillows? - in detail
Dust mites thrive in the warm, humid environment of pillow fillings. Their presence can trigger allergic reactions and degrade sleep quality. To eradicate them, apply a combination of thermal, mechanical, and chemical strategies.
Identify the infestation first. Look for dark specks on the pillow surface, a musty odor, or increased sneezing after lying down. If symptoms appear, treat the bedding promptly.
Effective eradication methods:
- Hot water laundering – Machine‑wash pillow covers and removable inserts at 60 °C (140 °F) for at least 30 minutes. High temperature destroys mite exoskeletons and eggs.
- Steam cleaning – Apply steam at 100 °C (212 °F) for 5–10 minutes directly to the pillow surface. Steam penetrates deep fibers, reaching mites hidden inside.
- Freezing – Place non‑washable pillows in a sealed plastic bag and freeze at –18 °C (0 °F) for 24 hours. Extreme cold kills both adult mites and their eggs.
- UV‑C exposure – Expose pillows to calibrated UV‑C light for 15 minutes per side. UV‑C disrupts mite DNA, preventing reproduction.
- Chemical acaricides – Use EPA‑registered sprays containing benzyl benzoate or permethrin. Apply according to label instructions, ensuring adequate ventilation.
- Silica‑based powders – Dust pillows with food‑grade silica gel or diatomaceous earth. These desiccants absorb moisture from the mite’s exoskeleton, leading to dehydration.
- Essential‑oil solutions – Mix 10 ml of tea‑tree or eucalyptus oil with 1 L of water, spray lightly, and allow to dry. Oils possess acaricidal properties without leaving residues.
Prevent re‑infestation:
- Encase pillows in allergen‑impermeable covers with zippered closures.
- Maintain bedroom humidity below 50 % using a dehumidifier.
- Air pillows in direct sunlight for 30 minutes weekly; UV radiation reduces mite populations.
- Replace synthetic‑filled pillows every 2–3 years; natural fillings such as wool resist mite colonization better than polyester.
Combining heat, moisture control, and periodic chemical treatment provides comprehensive elimination and long‑term protection against dust‑mite contamination in pillows.
