Efficacy of a sheep fat-based deer repellent based on research in up-state New York

Stephen M. Vantassel, host of Living the Wild Life, summarizes research on Trico deer repellent (EPA# 71637-2) which was tested outside of Rochester, NY on yew plants (Taxus media "Hicksii"). Interestingly, it was also tested against the popular repellent Plantskydd. The repellent is registered for use against deer, moose, elk, and rabbit browse and rub damage.
