CMa2e887, and welcome! I see you recently joined our community website (earlier this morning), and we are glad to have you here! It's also nice to see you jumping right in to the forums section.
When it comes to dust mites, it is always helpful to keep one's living space clean and free of dust. This is not always easy and it is best not to overdo this, either.
We do have a wealth of information published, right here within our asthma.net community, which focuses on this very topic. For your convenience, here is a link to several of those articles: https://asthma.net/search?s=dust%20mites. I do hope you find the information is helpful for you, in a practical way. Some of the information specifically addresses your concerns.
Wishing you well,
Leon (site moderator asthma.net)
