For what it is worth, I have been using Frontline spray with my ferrets
for 7 years and have experienced no negative effects on my ferrets nor
myself by handling them or administering it.
 
Personally, it is the my flea control product of choice.  Also, I have
been told to use it for earmites, but I prefer ivomec for ear mites and
heartworm protection.
