1. Why are Plant Pro-Tec UNITS effective? The repelling formulation in Plant Pro-Tec UNITS is based on long known data that the garlic odor repels browsing animals. Our product contains a strong, long lasting garlic odor that discourages browsing animals from feeding on or around treated plants. (back to top)

2. Why are Plant Pro-Tec UNITS long lasting? The garlic odor from an activated Plant Pro-Tec UNIT is evident for 6 to 8 months, a whole growing season! The garlic odor lasts a long time for two reasons: 1) The garlic odor is from concentrated garlic oil- one ounce of the garlic oil is equivalent to 200 pounds of fresh garlic! 2) We have created a slow release system. Sulfur compounds give the garlic its repelling odor, and if exposed to air, sulfur compounds oxidize. As oxidation occurs, the garlic odor dissipates. It is the same as watching an exposed apple core turn red with rust as it oxidizes. We prevent oxidation of the sulfur compounds by sealing out air with a plastic cone ( See cross section diagram, at left). The cone, however, allows the garlic odor to slowly permeate through. Without the cone the garlic odor would be evident for 1 to 2 months. With the cone the garlic odor is evident for 6 to 8 months, a whole season! Another reason the repelling garlic odor is long lasting is that the garlic formulation is not affected by rain or irrigation water. Although a Plant Pro-Tec Unit has a rain-shield, we still recommend that UNITS be clipped on sideways to prevent water from getting in. Water cannot dilute the formulation, but it can create a barrier which prevents the garlic odor from escaping. No repelling odor, no repellency! Another question that we often get is "Why can't I spray garlic juice or hang garlic cloves on my plants?" . The answer is that you can, but the garlic odor will be gone in several days because of the oxidation of the sulfur compounds that give the garlic its repelling odor. (back to top)

4. Why are Plant Pro-Tec UNITS economical? Plant Pro-Tec UNITS are economical because only one application is necessary to last a whole growing season. Also, with a shelf life of one of more years, any UNITS not used this year will still be effective next year. (back to top)

5. Will my yard smell of garlic? The honest answer is that if you smell garlic at all, you will probably get hungry for Italian food. In ten years of selling Plant Pro-Tec UNITS we have never received any complaints about the garlic odor. Although the garlic odor from a Plant Pro-Tec UNIT is not strong to most people, deer and rabbits are generally very sensitive to it. (back to top)

6. Can Plant Pro-Tec UNITS be used to protect plants in forests, vineyards, and orchards? Plant Pro-Tec UNITS are also used in forests, vineyards and orchards. Models for these uses are blue and white instead of green and white for the model used in lawns and gardens. The blue color stands out making it easy to keep track of where the UNITS are placed. The green color blends in with plants. For more information about using Plant Pro-Tec UNITS in forests, vineyards, and orchards, contact Dr. Jerry Walters at 1 800 572-0055. (back to top)

8. Who invented Plant Pro-Tec UNITS? Plant Pro-Tec (Garlic) UNITS were invented by Dr. Jerry Walters. As a Research Forester and a home owner, he kept losing research and landscape plants to deer. After trying every repellent available with poor results, he invented Plant Pro-Tec (Garlic) UNITS. Because Plant Pro-Tec (Garlic) UNITS were invented and developed with Jerry's time and resources, a private U.S. Patent was issued in 1992. Over 8 million UNITS have been sold. Today Plant Pro-Tec (Garlic) UNITS are the best, longest lasting repellents on the market. (back to top)
