If your tank is glass, cleaning it with a 10% bleach solution will kill any mites and eggs on the glass.

Take your wood hide and branches and put them in your oven on 180 for 20 minutes.

Soak the snake in warm water WITH dishwashing liquid added for 30 minutes.

Do NOT put the wood with the snake until you are sure the mites are gone. Just put it on newspaper with a waterbowl. If it needs to hide, put some extra newspaper in there for it to get underneath.

Then get pam and follow directions.
