Best Deer Repellent, Bobbex Rated #1

The Best Deer Repellent was revealed through an independent study conducted by the State of Connecticut Department of Forestry and Horticulture. Conducted by Jeffery S. Ward and Scott C. Williams during the growing season of 2006 – 2007, this test was structured to determine the true effectiveness of leading deer repellents in the deer-saturated Connecticut region.

To determine the Best Deer Repellent, ten different commercially available deer repellents were tested in two different geographic locations, using deer-attracting Evergreen Yews. To establish benchmarks, both positive (fence) and negative (no treatment) controls were included in the experiment.

The Evergreen Yews were planted in 2 “garden blocks” at each location, with each block containing 12 groups of 6 yews. Deer Repellents were applied based on manufacturer’s label recommendations, with a different repellent treatment randomly assigned to each group of yews within each block.

Application costs were recorded, and a Protective % Index was established to grade the effectiveness of each product tested. Results were determined by measuring plant size and dry needle weights at the end of the 2007 growing season.
