My goats are being eaten alive by flies. I wanted to know if I made up a mixture of garlic oil and water, or vinegar and water and sprayed my goats, would this hurt them?
Straight Apple cider vinegar in a spray bottle works great on any livestock. It is what I learned to use as a kid in 4-H.
I have a friend that buys Avons-skin so soft. and she applies it with a sponge to her horses. It does keep the flies off of the animals.
Instead of treating the goats, why not kill the flies? Buy some Beneficial Nematodes, and let the microscopic buggers kill all the fly larvae before they even become flies.
