I bought the anti-mosquito product from Homeoanimal. I have bought mosquito repellents in other horse stores, but the effect only lasted 30 minutes. With this Homeoanimal remedy, my horses are protected for 24 hours.

For prevention I give it 2x per week with a little water in a bottle cap (I have tested several ways to administer it and this is the easiest, according to me and my cat). My cat drinks it all without any problem. In terms of effectiveness, I trust this remedy. I can't really tell if my cat has been bitten...mosquito bites tend to go unnoticed...but I haven't seen my cat scratching.
