NIX EVERYTHING!!!!!!!!!
NIX all hides and let the nix dry (that's how it works!)....... spray your snakes so they are very wet with the soloution and do not give them a water dish for at least a day.
spray the area around the tanks and let it dry also....... do not wash it off! Spray the tank, and anything else the snake goes near with a light misting and let it dry also. if you use any substrate, throw it out. spray paper towels with nix all over and let them dry before putting them in the tank with the dried nix solution.
your mites will be gone, don't worry.
Do the whole thing all over again in a week........ spray any new animals that come into contact with your snakes with nix too. I keep a bottle of it handy at all times, and you'll have LOTS left over even after 2 whole treatments.
If you mix it with a gallon of water (distilled water!!!!!) it is not toxic to them, so if in doubt, nix the hell out of it! Just mix it into the bottle, then pour that into a spray bottle as you need it.
Yes, nix everything, all plastics (mites can most certainly get on plastic) and anything in, on or around the area..... i believe you are to also spray at least a yard around the tank, as in the floor and walls.
Again, do not wash it off.
Hope that helped.......
