I just moved into a new home here in Atlanta and had to do quite a bit of remodeling. The floors were in really bad shape, and I decided to rip up the remaining carpet, pull up all the nails and tacks, sand the original wood floors, and refinish them. I am very happy with the results! Now the dust mites won't be able to hide in carpet!
If you decide to remodel your home, be sure to wear a mask (especially if you're sanding floors). Construction dust is particularly harmful to the lungs. You can also seal off rooms with plastic and work on them individually to prevent contaminating the air in the whole house.
Ventilation is important, too. Be sure to open windows and doors when you're working with paint or other chemicals.
