I tried the Natural Defense spray. I don't like the chemicals either, but had such a battle with fleas this past year I can't even tell you how frustrated I was. It seems like I tried everything and nothing worked. The only thing I didn't use was Advantage or Advantix. Frontline didn't work, bathing regularly didn't work, Adams spray didn't work in the house or on the dogs, bombing didn't work. I used Biospot this last time, which I thought was the el cheapo stuff, but haven't had any fleas yet, and put it on them around Christmas. Never had an infestation all year, but would find about 5 fleas on each dog every time I bathed them (every 2 wks or so). This coming fleas season I'm going to start with the Advantage or Advantix and then alternate with the Biospot. I never used to have to use flea stuff all year long, this is the first time in years that I've used it more than 4 months out of the year.
No Fur, No Paws, No Service.
