Go to wallyworld and look for Sawyers Tick repellent, in the green can.
And get a plastic tote or a pillow case with a tie string to keep it in while treating the cage.
Step one - get the snake out of the cage and place in a tote or the pillow case.
step two - Remove the water bowl from the tank and cut off all the heat sources,
UTH,
CHE lights etc.
Step three - Spray the inside of the cage, stirring up the existing substrate and spraying it well aslo.
You will want to end with the cage foggy from the spray. Spray the floor around the cage also, but not enough to rasie a mist.
Mites trave and it is very likely they are in the carpet or floor around the cages.
Step four - Cover the tank with a sheet or a towel to keep the fumes inside while it works on the
mites.
Step five - While the fog in the tank is being settled, give the snake a bath in slightly tepid water, to get as many
mites off it as possible.
Step six - After letting the fog in the cage settle for a minimum of two hours, place the snake back in the tank. You can also replace the water bowl at this time, but I normally wait till the next day.
Step seven - What ever you used for holding the snake, whether it is a pillow case or a tote, spray it also to eliminate any
mites that may be present and left behind.
Be on the look out for the next two weeks for any new
mites that may hatch and treat as needed.
Mites have a two week life cycle, so it is possible in two weeks you may need to repeat the treatment.
Aslo, very important.
Do NOT spray, rub or put ANY of the spray directly on the snake or any reptile, PERIOD. It can prove to be detrimental for the snakes health and possibly lead to death.
As long as you treat only the cage and not the animal, it is very safe.
