Their destruction is unsightly, permanent and often very expensive. For over 25 years, Redding Nursery has been protecting plants from damage with a unique formulation called DeerPro. DeerPro is a thiram-based repellent developed by James McNamara, which prevents deer from eating woody ornamental plants during the winter months. And with DeerPro, one spray lasts all winter long.
