Did you know that wall-to-wall carpeting can hold up to eight times its weight in trapped dirt, dust mites, chemicals and pesticides? While it may not be green to rip up your carpet and replace it with hardwood floors, you can be mindful of what goes on in rooms with carpeting. First, make a habit to not wear shoes in carpeted rooms. Second, if you get your home treated by an exterminator, ask him or her not to spray directly onto the carpet but on the baseboards. Insecticide chemicals can settle in carpets and remain there for many years, accumulating each time you have your home treated.
