Wild animals are delightful when they wander in natural habitats. But not so much when they come into your backyard. This Plantskydd deer repellent offers all-season protection for your annuals, perennials and trees. It's all natural so it won't harm deer, elk, rabbits, moose and other creatures looking for a tasty treat. The liquid repellent is best applied in late fall or early spring. It will protect dormant plants for up to six months and active ones for three to four months. It's also cold weather resistant and won't wash off when it rains.
