Farnam Equi-Spot Spot-On Protection for Horses, protects up to 14 days 0.34 fl. oz.

I used this on 3 of my horses and 2 were fine. The third one is a 6 year old, fit Gypsy Vanner. After I applied the Equi-Spot I continued to groom her and within 15 minutes she began getting very agitated, biting and kicking at herself and scrubbing her head on the fence until it bled. It took me a minute to realize it was exactly where I had applied the Equi-Spot. I had to bathe her twice before she stopped. She was so out of her mind I thought she might inadvertently injure me as I worked to get it off but I escaped unscathed. The other 2 horses showed none of these signs at all other than rolling. 24 hours later there are no flies on them! If you haven't used this on your horse before I would apply it to one spot where it would be easy to wash off and wait 15 minutes before applying the rest. I did pour it into a syringe to make it easier to apply.

This is the second time I've purchased Equi Spot to use with my horse and I never had any problems until this new order. Freia became very disturbed when I attempted to apply it on her and was obviously in some distress (burning her?). She had the same reaction three weeks ago when I tried to apply it, but, I just thought it was something else bothering her. It was very evident today that it was the Equi Spot that was causing the problem because she was very calm before I attempted to apply it. Maybe, the formula was changed or we just got a bad batch but I won't be using it again! Once we washed the Equi-Spot off, she was fine.

Sadly, donkeys are fly magnets and our donkeys are no exception. The flies torment them something terrible and we have a hard time keeping them away with the twice-daily fly-spraying that has always worked for our ponies. I was looking for something to help and this seemed to do it. There are still flies, but they're better managed with daily sprays as long as I keep up on the Equi-Spot. I was concerned about sensitivivity, but none of our four (three donkeys and a mule) have showed any difficulties. The product is a bit difficult to apply without making a mess (even if you follow the video instructions) so an improved applicator would be nice, but it's not unmanageable.

Belgian reacted immediately, tried to scratch everywhere treated for about an hour, then settled. Arabian and Pony did fine with test spots, so treated the entire horse the next day. Pony did fine. The Arabian had sizable welts where treated the next day. Disinclined to repurchase, but at a loss as to what else to try for the terrible ticks this year!

I've used this off and on for a couple of summers, and while it definitely helps keep ticks off my horses, they absolutely hate it when I put it on. One of my mares will literally trot off when she sees me coming with it, as soon as she hears the 'snap' of the capsule or smells it. My gelding stands quietly as I apply it, but once it starts to soak in on his legs, he proceeds to chew intensely at his skin. I can only surmise that it is irritating to them. I've given up on it and have gone back to rubbing repellent lotion on their bellies and wiping spray on their legs and bodies.
