How to get rid of dust mites in a sofa? - briefly
Vacuum the sofa using a HEPA‑filter attachment, steam‑clean the fabric, then apply an approved acaricide spray and maintain low humidity with regular cleaning to prevent mite recurrence.
How to get rid of dust mites in a sofa? - in detail
Dust mites thrive in upholstered furniture because fabric cushions retain moisture and organic debris. Effective eradication requires a systematic approach that combines cleaning, environmental control, and preventive measures.
First, remove all removable covers, cushions, and pillows. Wash them in hot water (minimum 60 °C) for at least 30 minutes; this temperature kills mites and their eggs. If the fabric cannot be laundered, place the items in a sealed bag and expose them to direct sunlight for several hours, as ultraviolet radiation and heat are lethal to the insects.
Second, vacuum the sofa thoroughly with a HEPA‑filtered vacuum cleaner. Use the upholstery attachment and pass over each surface multiple times, focusing on seams, crevices, and the underside of cushions. Empty the vacuum bag or container into a sealed plastic bag immediately to prevent re‑infestation.
Third, apply a suitable acaricide. Choose a product labeled for indoor use on fabrics, following the manufacturer’s dosage instructions. Spray the solution evenly, allowing it to penetrate the fibers, then let the sofa dry completely before reuse. For households preferring non‑chemical methods, a 50 % solution of white vinegar can be misted lightly; the acidic environment reduces mite viability.
Fourth, control humidity. Dust mites proliferate when relative humidity exceeds 50 %. Use a dehumidifier or air conditioner to maintain indoor humidity between 30–45 %. Place a hygrometer near the seating area to monitor levels regularly.
Fifth, implement preventive habits. Rotate and fluff cushions weekly to disrupt mite habitats. Use dust‑mite‑impermeable covers on upholstery; these barriers prevent colonization while allowing normal use. Vacuum the surrounding area at least once a week, focusing on carpets and nearby furniture that can serve as secondary reservoirs.
Summary of actions:
- Launder removable fabrics at ≥60 °C or sun‑expose them.
- Vacuum with HEPA filter, emptying waste promptly.
- Apply approved acaricide or dilute vinegar spray; allow full drying.
- Keep indoor humidity below 50 % with dehumidification.
- Use protective covers, rotate cushions, and maintain regular vacuuming.
Consistent application of these steps eliminates existing dust mite populations and creates an environment hostile to future infestations, ensuring a healthier sofa for occupants.
