How can a house be treated for dust mites? - briefly
Reduce mite numbers by eliminating carpets, washing all bedding in water above 130 °F weekly, and vacuuming with a HEPA‑rated cleaner. Apply acaricide treatments, encase mattresses and pillows with dust‑mite‑proof covers, and keep indoor humidity under 50 %.
How can a house be treated for dust mites? - in detail
Treating a residence for dust‑mite infestation requires a systematic approach that combines physical removal, environmental control, and, when necessary, chemical intervention.
First, eliminate existing populations. Wash all bedding, curtains, and removable fabrics in water hotter than 130 °F (54 °C) for at least 30 minutes; dry on high heat. Vacuum carpets, rugs, upholstered furniture, and mattresses with a HEPA‑rated vacuum cleaner, moving slowly to allow suction of mites and their feces. Follow each pass with a thorough wipe of hard surfaces using a damp microfiber cloth.
Second, reduce humidity, the primary factor sustaining mite growth. Maintain indoor relative humidity below 50 % by using dehumidifiers, air conditioners, or ventilation fans. Install hygrometers in high‑risk rooms (bedrooms, living areas) to monitor levels continuously.
Third, create physical barriers. Install allergen‑impermeable covers on mattresses, box springs, pillows, and upholstered furniture. Ensure seams are sealed to prevent mite ingress. Replace heavy drapes with washable blinds or light‑weight curtains that can be laundered regularly.
Fourth, apply targeted chemical controls if infestation persists. Use acaricide sprays or powders labeled for indoor use, following manufacturer instructions precisely. Apply to cracks, crevices, and the undersides of furniture where dust accumulates. Limit exposure by ventilating rooms and keeping occupants, especially children and pets, out of treated areas until the product dries.
Fifth, consider thermal treatment for items that cannot be laundered. Expose objects to temperatures above 115 °F (46 °C) for a minimum of 30 minutes, using portable heating units or professional services. Heat effectively kills mites at all life stages.
Sixth, schedule regular maintenance. Repeat washing of bedding weekly, vacuuming twice weekly, and humidity checks daily. Replace encasements every 12–18 months or sooner if damaged. Conduct quarterly inspections for new mite colonies, especially after seasonal changes.
Finally, if self‑managed measures fail, enlist a licensed pest‑control professional. They can perform comprehensive assessments, apply advanced acaricides, and offer customized remediation plans that align with the home’s layout and occupancy patterns.
