"Happy Jack Frost", a sensitive mule, finds this combination of a popular bath oil, reputed to have insect repellent properties, to his liking. Add about 12 drops per ounce of Eucalyptus Essential Oil to this product for an effective rub. No need to spray. Just pour a little into the palm of your hand and apply. About one-fourth cup should be adequate and can increase or decrease according to size and location.
