I have a snake I picked up who had a cpl of ticks on it, which I removed. Ive gone over him completely and I dont see anymore. To be sure I went and got a bottle of mite off, and gave him a dose of it(sprayed him down). How often should I use it, and should I give my other snakes a dose, for preventive measures. The snake that had the ticks is in a tank in another area of the house away from my other snakes.

Here is a pic of him
