My guess is that you don’t know much about dust mites except they are small, unseen creatures that disgust you. Perhaps someone in your household is allergic to them. Here is some background information on dust mites and how you can work to control them in your house.
Dust mites don’t live in your air ducts, although most people tend to focus there when attempting to remove them. They live in soft places, prefer higher humidity and release a protein which causes an allergic reaction for many people. If you don’t have any reactions to dust mite proteins then reducing your exposure may not be a priority for you but these basic treatment steps should still be taken to reduce their presence in your home and affect on your life. If you need motivation to do some of these steps you can see pictures of dust mites by doing a google image search. They’re gross enough to scare anyone into a rapid cleaning spree.
1. Dust and vacuum your house on a regular basis. The more dirt you have, the more dust mites you have.
2. Use a dehumidifier to reduce the humidity levels in your home as they prefer high humid environments (anything over 70%)
