Carpets collect dust, dirt, and other small debris due to the frequency of foot traffic in those areas. If these unwelcomed particles are not eliminated, germs will grow and multiply beneath your carpets. Harmful bacteria can affect the indoor air quality of your home, which in turn, can cause health problems to you and your family. Skin rashes and asthma are just some of the illnesses that you and everyone in your household may catch if there are parasites living under your floor coverings.
