The Liquid Fence Deer and Rabbit RTS works on scent so deer and rabbits don't even have to take a bite to be repelled. Includes the QuickFlip hose-end sprayer, which activates spray at the flip of a switch! It does not have to be rotated with other repellent brands because animals' natural aversion to the scent will never diminish. It can be applied year-round and is harmless to plants and animals.
