Amy's Opinion: Excellent for black flies and mosquitoes. I've even made fly spray myself with tea tree oil, vinegar, and other stuff, but this stuff is so much more effective. Bite Blocker has been proven 97% effective! It's sweat-proof and child-safe, with 4-8 hours of protection! On a really bad bug day, I apply again after 4 hours. Pleasant fragrance, my horses don't mind it a bit.

Non-Toxic, Non-Flammable, and won't harm plastics or the environment. Click here to see a study on Bite Blocker's effectiveness.
