Cold water leaves up to 10 percent of mites behind. Dry cleaning kills all mites and is also good for removing dust from fabrics. If you have taken as many of these actions as practically possible and are still having allergic reactions to house dust mites, allergy shots may help. A dust mite extract can be formulated to boost your immune system's response specifically to dust mite allergen. Shots for this purpose have been shown to be very effective.
Dust mites are probably impossible to avoid completely.
Still, they don't have to make your life miserable. Your doctor is an important resource in helping you to keep dust mite allergies under control. Talk to him or her about measures you can take, sources of more information and of allergy products, and whether immunizing shots may be right for you. Together you can prevail against the effects of house dust mites. This information should not substitute for seeking responsible, professional medical care.
