YIKES NEVER use Hartz products. Horribly dangerous and they don't work http://www.hartzvictims.org Sergeants shouldn't be used, either, as they're owned by the same company. 20 Mule Team Borax CAN work in the carpets but not without also treating the pets. Flea bombs are useless and VERY dangerous with pets running around a house - especially ferrets. Just think - they're walking on surfaces and licking their paws and ingesting that poison. I've heard some say that fleas have grown a resistance to Frontline. Try Advantage. When I first bought my home I found out the hard way that the prior owner had left the backyard infested with fleas from his hunting dogs. I let my two cats out for some photos (since it's fully fenced) and my home ended up infested with fleas because only my dog was protected. I put Advantage on all the cats and then split a vial between all my ferrets and also combed them daily for any since it completely freaked me out to see them on the ferrets. The fleas were completely gone in about 10 days and in five years I haven't seen anymore.
