UltraShield Brand Residual Insecticide & Repellent

Absorbine Ultra Shield Fly Spray

The most technically advanced, ready-to-use fly repellent provides the ultimate protection for your horse. It repels flies, mosquitoes and gnats on horses for up to 5 days.

Fly Spray Note: Natural Pyrethrins and synthetic Pyrethroids kill and repel in the same manner. They are tactile, that is, the fly must land to be repelled and to pick up the insecticide in order to be killed. The spray does not produce an invisible shield around the treated animal to repel flies. The fly will land on the horse, but will not stay to bite. This contact with the insecticide repels the fly and later kills it by attacking its central nervous system.
