Can I get rid of house dust mites?

Getting rid of house dust mites is next to impossible. This is because they can live almost anywhere in your home, especially on soft surfaces like bedding, carpets, rugs, curtains, and clothes. Even really clean homes can still have house dust mites. You can also come in contact with them in other people’s homes, or places you stay when you travel. However, there are some things you can do to help keep them in check.
