We have been using this product for several years now on our calves when we castrate them. We have never had any problem with infection or flys. Easy to spray on, good product

Works well for alpacas with ear ticks. If I see an alpaca with an ear "down", I spray it in the ear and massage it in (alpacas like that!), and usually the ear is up in a day or 2.

I use this stuff when all other fly products don't work.You squirt a little in your hand and rub it on the effected area. It usually lasts well over a week. In the long run you actually save money by using this as you don't have to re-apply it very often.

GREAT spray for dogs' ears that flies are biting! Keeps the biting flies away and helps heal the ears up if the tips are already bloody.
