Replace your furnace filter with a high-quality allergen-rated filter. These filters specify on the packaging that they will trap dust mites. To get rid of the mites on your floor will mean preventing them from being blown into the room.
Clean your hardwood floor with an electrostatic dust mop. This type of mop will collect the dust mites rather than pushing them around. Make sure the mop is machine washable. Hot water is needed to kill dust mites.
Vacuum drapes and upholstery once a week, using a HEPA-filtered vacuum cleaner. While dust mites cannot live on hardwood floors, they thrive in areas such as carpets and curtains where dead skin may accumulate. You may not think your drapes are accessible to mites. However your furnace will blow them throughout the house and they will collect on cloth-covered surfaces.
Air out your house as often as possible and try to keep your thermostat at 70 degrees or lower. Dust mites cannot survive in temperatures below 70 degrees.
Consider replacing your upholstered furniture with leather and your drapes with blinds. Likewise, protect your mattress and pillows with dust mite proof covers. This will eliminate the places where dust mites can survive, ridding your hardwood floor of the residue they leave.
