I am thinking about pretreating new feeder breeders with ivermectin as a mite preventative. From what I have read, for a rat you can put one drop behind the ears of the liquid or a rice size grain of the paste horse wormer orally for larger ones and half a piece of rice size orally for the smaller rats. Thought I would try it on a few and see how they do before treating the whole batch. Ivermectin can be given to snakes orally as a wormer, so what is not processed would be a safe amount for a snake I presume, at least safer than poisons. The ivermectin can also kill othert parasites, an additional bonus. Hopefully more people will chime in.
