Herbal Flea and Tick Remedies for Pets
Try the book All You Ever Wanted to Know About Herbs for Pets, by Mary L. Wulff-Tilford and Gregory L. Tilford, Bowtie Press, 1999. It contains some recipes for flea and tick repellents and rinses for pets. Some of the multi-ingredient concoctions may seem a little complicated, but most of the herbs and essential oils are available in a good health food store. Note, what you use for yourself is not necessarily safe and effective for Fido, and vice-versa.
