Thanks, Zorah, and Bebop,
I am concerned too about having the yard sprayed. I have a garden as well, and the idea of runoff into the garden is a great concern. So, I'll probably just try to control the fleas in the house and on the pets. Last night, after the Dawn soaking and rinse, Fozzie was completely free of fleas, and this morning as well after a night in his kennel cage in the house, not in the garage.
I think fleas have become resistant, or immune, to the flea products out there, and it is a real problem.
