How did you get dust mites entirely out of your house?

Basically a two step process: 1. Keep humidity at 40% year round, using dehumidifiers. This stops their biology and makes them go dormant quickly. Their eggs and protonymphs will die out after a year or so. 2. Remove existing allergens from your home. In short: allergen covers around your bed, get rid of old fabric stuff(curtains, rugs, carpet). Launder everything you can on the highest heat possible.

Internet says to keep humidity below 50%, so a dehumidifier.
