Here’s how to keep deer from eating your garden and landscape plants

 Yes, seeing deer and other wildlife in your yard can be adorable. But not when they’re eating the prized plants in your garden. When deer treat your carefully cultivated landscape like it’s a salad bar, it’s time to do something about the deer.

A new generation of deer and wildlife control products is now available that keep deer and other critters away—without using harsh chemicals. From ultrasonic devices to innovative repellents, here are some new ways to keep hungry deer from lunching in your garden. 


Solar-powered, motion-activated pest control


Solar Yard Gard from Bird-X

Here’s a high-tech way to keep deer and other pest animals out of your yard without using poison or traps. The Solar Yard Gard is a solar-powered ultrasonic pest control device that uses sound waves to keep deer, squirrels, raccoons, rodents, skunks and other animals away from your valuable landscape plants. Humans can’t hear the high-frequency sound emitted by the Solar Yard Gard, but animals hear it and keep away.

Just set up the device in a sunny area. The ultrasonic waves are activated when the motion detector senses an animal. When pest animals activate the Solar Yard Gard, the ultrasonic waves irritate and annoy them so they seek calmer, untreated areas. One device will protect up to 3,000 square feet of landscape. Simply use additional units for larger areas. Not only does the safe, easy-to-use Solar Yard Gard protect plants, but it helps prevent the spread of ticks that can carry Lyme disease. The Solar Yard Gard sells for $49 at and fine hardware stores. For more information call (800) 662-5021.


Use the scent of a predator to repel deer

Deer Ban package web

Summit Deer Ban

Summit® Deer BanTM repellent capsules keep deer from eating flowers and other landscape plants by tricking deer into thinking that a predator is nearby. Each Deer BanTM capsule contains predator urine that triggers a deer’s animal flight response.

Deer BanTM uses a unique gel-tablet application to provide 100% effective, year-round protection from wildlife damage. Just set out the capsules on the ground every 5 to 10 feet around the plants you want to protect. Then water the capsules to release the active ingredient for up to 90 days of protection. When activated by water, the polymer gel releases the scent of predator urine, which keeps deer away. Deer BanTM is odorless to humans, and your hands never touch the active ingredient. There’s no messy spraying, and no mixing or measuring.

Unlike many deer repellents that wash away and become inef­fective after rain, water actually enhances the effectiveness of Deer BanTM because the polymer gel needs to absorb water to activate the odor of the active ingredient. The biodegradable Deer BanTM will continue to be reactivated by rain or watering for up to three months.

Summit® Deer BanTM is available in packages of 20, 50 and 150 capsules at fine hardware stores, garden centers and online at Summit Responsible Solutions also makes Mosquito Dunks®, Mosquito Bits®, and Summit® Year-Round® Spray Oil and other pest control products.


Systemic repellent keeps deer and rabbits away from plants

Repellex Systemic Granular web

Repellex Systemic Granular

Repellex® Systemic Granular is a patented formula that delivers a hot pepper concentrate through plant roots, making the plants unpalatable to animals. Because the active compound is protected inside the plant cells, it doesn’t wash off in the rain or degrade in sunlight. Efficacy is greatly improved because the long-lasting compound maintains its potency and is evenly distributed throughout the plant.

Just rake the granular product in the soil around the plants you want to protect. The repellent compound dissolves during watering and enters through the plant’s roots, spreading gradually throughout the plant. The natural pepper extract is distributed evenly throughout the plant, so that all parts remain protected. Depending on the health and size of the plant, this can take as little as a week or as long as a month. (A foliar spray may be used during this period for plant protection.)

Repellex® Systemic Granular is not intended to be used on edible plants, and the product is not available to consumers in California. A 1.5-pound container of Repellex® Systemic Granular sells for $17.99 or a bottle of 50 pre-measured Repellex® Systemic tablets sells for $19.99 at local home centers, garden center stores and online at
