The crazy thing is that 3 different people in a chat on another snake forum all said it was safe to use. They said to take a teaspoon of the powder and mix it up in the aspen. As I said before I am using the method I talked about above. I have already done the known infested snake and cage. The others don't show any signs of mites but I will treat them and thier cages as well. Do you see any reason I may need to repeat the treatment in a week even if I see no more signs of mites?
