Dust mites may love hanging out in soft bed linen, but they hate smooth surfaces. If you can, do away with upholstered couches and chairs and go for wood or vinyl instead. Also get rid of rugs and carpets, and replace them with wood, laminate, or tile. Even if dust mites do gather on these hard floor surfaces, they’re easier to clean with a damp mop. If you do keep your carpets, vacuum religiously.
