I have been using Food Grade Diatomaceous Earth for years to kill fleas, ticks, bed bugs, parasites naturally on my dogs. I put it in the food too, put it on dogs coat and rub it in good. Make sure you buy the FOOD GRADE kind and not the kind used for swimming pools. I order mine from Dirt Works. Check it out..its wonderful for humans..many good uses.
