I have used the food grade DE for a flea outbreak we had a couple years ago. It worked wonders. I did not like how it made my pups' fur feel chalky, so it is not something I would do instead of flea preventative, but we still have some and I would use it again should we have a flea infestation.
Definitely do not use the stuff they use in pool filters or to line fields on your dogs. ONLY food grade DE!! |
