| Hi Steve,
I know a mate of mine has used TOD on elapids in his collection and from what i am told (i.e. he has never mentioned) that there has been no ill effects from it.
Mind you the animals are in very big enclosures, as they are display animals, thus the concentration of the spray used would differ.
So yeah though i know that he has and does use it, i dont know exactly what he is doing when he uses it.
As for treating of mites, regardless of animal, i have always found best to remove the animal to a different part of the house and have it in a bare plastic tub with a water bowl and heat mat for about two months. This means that you need to give the tub a wipe out every day or so to get rid of the mites there.
Essentially you just need to break the cycle and you have it. Any animals that are still living in the enclosure are going to die as they dont have a food source, and the mites on the animal, provided you keep cleaning out the tub etc, (thus stopping the breeding cycle in that location) you shouldnt have an issue.
Best of luck with it
Cheers
