Deer Gard uses a battery or mains-powered motion detector that is continually scanning your property 24/7. Once a deer or other large critter triggers the sensor, the device emits a loud ultrasonic sound. This annoys the deer and they retreat. Repetition of this teaches the deer not to come onto your property, so the Deer Gard is a humane, effective, and long-term solution.

You can use mains power for Deer Gard if you like, otherwise, it can be powered completely by batteries. The device comes with 20 feet of power cord that you can connect to mains power but otherwise, works perfectly well with batteries.

We would suggest periodically checking the batteries to ensure they still have sufficient charge.

Deer Gard is humane because it doesn’t harm animals. Home Shielders doesn’t believe in any deterrent or repellent that harms animals. We all need to learn to live together while respecting each other’s boundaries.

It uses an ultrasonic frequency inaudible to humans but annoying to deer and other critters. It is this sound that deters them. There is no permanent damage and chemical or physical deterrence required.

Yes, it does. As long as you position the motion sensor so it can detect other creatures, it will detect and deter them. We know it works on raccoons, squirrels, skunks, opossums, and other mammals as we have tested it.

The key is in the positioning of the device. Make sure the motion sensor is low enough to detect smaller mammals and place it close to where they enter your property. The motion sensor should detect even small mammals and provide that audible (to them only) deterrent.

Yes, it is. Pest or animal control needs to be in place to capture the deer or to place traps. Neither are ideal solutions and can cause distress to the animal. Even the most careful handling of a deer will cause immense stress, which isn’t an ideal outcome.

The Deer Gard is a fully automatic, hands-off deterrent that uses sound waves. No distress, no stress. Just an annoying sound that should drive away even the most determined deer.

That’s impossible to say as all deer are different but customers have told us that it can begin working right away. Some deer will get the message immediately and not return. More stubborn deer may require a visit or two to get the message.

Either way, we would fully expect Deer Gard to begin reducing unwanted visitors to your property within a few days at most.
