Ditto, with a few other additions. I also pre-treat bedding about once every 3 months. **Spray it on the Aspen, shake it up and use as needed (when I was using paper, I pre-treated the paper).
Treat animals before bringing them in with RR and have their tubs pretreated and the area where I open the box, too. Haven't had a mite infestation yet...knock on wood!![]()
