I live in South Florida and the fleas are a killer this year! We have been battling an infestation too. I think the key is to keep from bringing them back inside. We sprayed a yard spray by Virbac on the grass in the back yard where the dogs spend time outdoors. You can buy it online from Petco and Amazon but it was actually cheaper to buy from the vet. If your problem is really bad like ours was, I would recommend spraying the yard where your dogs spend their time then bomb your house a day or two after. You’ll need to treat the yard again in 10 days for the next cycle of fleas, but that should get most of them. That is what worked for us.
