Citronella Oil -- Equi-Ternatives, Inc.
If you haven't tried adding citronella oil to your regular fly spray, you should!! Just add a capful to a quart of fly spray. It boosts fly repellency, helps your fly spray last longer (it makes it slightly oily) and smells good, too. I add a capful of Avon Skin-So-Soft and a capful of Citronella oil to natural products like Larry's Horse spray, and it makes a great SAFE fly spray to use around kids or sensitive horses. It's sort of hard to find; try The HorseMart at email@example.com.
