When we have to deal with fleas, which is extremely seldom, I always use Adam's flea shampoo on the animals and their carpet spray on the carpets. I guess it's every 4 - 5 yrs we'll see a few fleas. The shampoo doesn't smell like insecticide, it leaves their coats soft, and is really effective. I know it's available coast to coast b/c my sister who used to work in an Army vet clinic in North Carolina is who got me using it here in Washington. It's the only product their clinic used – and I've noticed it the background in some of the clinics on the Animal Planet Animal Precinct shows, LOL
