So easy. I'm not sure why people always over react.
1) Take a roll of paper towel and unroll as many squares as you have snakes. (10 snakes = 10 squares of paper towel).
2) Spray Provent-a-Mite on the paper towel and allow it to dry (wait an hour to be safe).
3) put 1 square of paper towel in each of the snakes enclosures
4) repeat the same steps in 2 weeks or if paper towel becomes soiled.
DONE!
