Order Provent-a-mite and use it on the cage, all hides and stuff as well as outside around the cage, the table or whatever you have the cage on as well as make a circle around the floor like a barrier. Then repeat as directed on the bottle. It will take more than 1 or 2 or 3 treatments to get rid of them as they get everywhere. If its in a main room with furniture and drapes etc, you might need to spray the furniture and drapes as well.
