We are invaded by fleas. I had a cat, who was very old and sick. He has been gone for several weeks and there are no other pets in the house, except the hedgehog. I don't want to bomb or do something that is going to require me to scrub down the whole house afterwards, and evacuate for the day. I don't think this is necessary since we have no pets in the house. I live a few houses from the beach and there is constantly sand being brought into the house. I assume this is part of the problem. Any thoughts?
