my vet says you can kill mites and their eggs by drowning them in water actually. and if you use the search function you will find several posts by reptile experts including vets who use the same chemicals i have as well as frontline and proventamite and the like. all of these chemicals are dangerous with potential neurological damage occuring if ingested including proventamite. The chemical i used is extracted from chrysanthemums and should not be used on fringe toad lizards and invertebrates.
