1 part eucalyptus powder
1 part pennyroyal powder (use sage or rosemary for cats)
1 part fennel powder
1 part yellow dock powder
Combine all ingredients in a shaker top jar and shake to mi.
Apply to your pet's fur by brushing backward with your hand or comb and sprinkling the powder into the roots of the hairs. Concentrate on the neck, back, and belly. Use just enough to add a little odor to the hairs.
For severe flea infestations, treat daily; otherwise, use two or three times a week.
