Herbal Flea Powder

From the Book Eco Dog by Corbett Marshall and Jim Deskevich.

Combine as many of the powdered herbs as you can find.
Mix together equal parts of each herb in a shaker top jar
Brush your pet's coat backward with your hand or a comb while sprinkling the powder onto the base of the hairs. Apply sparingly, paying special attention to the neck, back, and belly.
Put your pet outside for awhile afterward, so his pests escape in your yard, not your carpet
