I've dusted my chinchillas and ferrets with DE and sprayed their cages with permethrin. There are other animals down there that don't belong to me but I was told they were being taken care of.

I take it they wouldn't be multiplying in the vast quantities that they are if there wasn't a host available to them. My dogs have been treated and there aren't any cats down there, they're 3 floors away.

I feel like I'm running around in circles. What bomb would kill the mites? I might do that in addition.
