Control moisture problems. Dust mites are found mostly in bedding. They can live in many other places, including upholstered furniture and stuffed toys. Regular cleaning is helpful. Small stuffed animals can be placed in the freezer for a few hours to kill mite eggs.
Mold needs moisture, a food source and mild to warm temperatures to grow.
Mold can grow just about anywhere there is high moisture. Mold problems are often visible. They can cause allergic reactions and asthma attacks. Some types of mold can cause severe illness, especially in the young, the elderly and those who are ill. A solution of laundry bleach, mixed according to directions on the bottle, will kill mold.
