growth inhibitors are very effective. But, the fleas need to bite the dog (or in some cases need extended contact) to be "dispatched". Not much of a help if your dog gets flea bite dermatitis.

For my own dog with allergies this is not an option. I used to use Dursban (when it was available) dip. Now its pyrethrin based dips.

Siphotrol premise spray by Vet-Kem (with Precor IGI) and Vedco Spot & Fog for the house/car etc work for me.

Not a cheap way to go but since I train dogs (incidentally, just down the road from you at a place with 300 dogs !) plus run my own Obedience business my dogs are "at risk".

It's been many years since I've had a flea "problem" using the above system.
