All houses have dust mites, which feed on skin debris from humans commonly found in house dust on floors and on mattresses. They can produce asthma symptoms in sensitive people. Some experts have claimed that up to 2,000 dust mites can live in one ounce of mattress dust. It is nearly impossible to eliminate them from your home, but there are ways to control them.
Try to keep your home’s humidity level to below 70 percent ( humans only require 35 to 45 percent relative humidity). You can do this by using exhaust fans in the kitchen and bathrooms, controlling moisture in the crawl space or basement, venting gas heaters correctly and if necessary, using a dehumidifier. Frequent vacuuming may help control mites, but it is also likely to stir them up so use a vacuum with allergen filtration, especially when vacuuming your mattress. It is more effective to replace carpet with wood floors.
Try to wash your bedding at least once a week in very hot water. Above 120 degrees if possible. Using a plastic mattress cover will go a long way to slow down mites.
Even your child’s stuffed animals can be full of dust mites. Kill them by placing the stuffed animals in a plastic bag and leaving them in the freezer over night. This may cut down your child’s sniffles.
