I have NO pets but there are a lot of stray cats roaming around and my neighbor across the hall has a huge dirty dog. fleas have moved into my place and are completely out of control. I boraxed *everything* in the house (heavily) and there is no relief. I used two cans of carpet/upholstery spray for my approx 900 sq ft. apt (the kind with an insect growth regulator) and fogged… there are still fleas hopping around and attacking my ankles! i figure i might have to fog a few times. any other suggestions?
