You could also go to one of those you do it yourself exterminator places and purchase what you need without bombing your house. We had to do that a couple of years ago in our house and it was much easier. You did need to go back and spray a second time to get the fleas that are still in the egg stage. The type we purchased we could as place on our animals and was not toxic to them. You really do have to be careful as many of the store bought products will make your pets very sick. One of my dogs, initially had a sensitively to flea bites, and we were allowed to treat him every three weeks. Maybe your vet would allow you to do so. Good luck.
