If your son or daughter is headed off to college and they have allergies to dust and dust mites make sure they keep their bedding covered with dust mite covers. It won't stop all the allergens but the will cut down on most of them.
You have kept them safe for years but now they are headed to a place you will not be able to clean. I would tell you to make sure they wash their sheets weekly in hot water but if yours are anything like mine were it won't happen.
