How Do Mechanical Deer Repellent Devices Work?

If you are starting to look into ways to keep deer out of your yard, there are a number of options you might be looking at. Scented products can be helpful, but sometimes a more physical or mechanical option can be the better choice. To make a smart decision for your situation, you should understand the various types of repellents and how they work.

Deer Fences

We should start with the simplest option, the fence. It’s not particularly mechanical but it is a physical deterrent that many homeowners first consider when they realize that deer have become a problem. Not the best option, though there are few ways to improve a fence for deer. A standard conventional fence will need to be at least 8 or 9 feet high in order to do any good. Your deer may even be able to leap over that if they’re motivated.

For something a little less daunting, you can try an electric fence. Granted, they can still jump over it but since it is not solid, a deer won’t see it immediately as an obstacle. When they sniff or otherwise touch the wire, the shock can be a powerful deterrent to keep them from going any further.

Water Sprinklers and Sprayers

Using a spray of water drive away the deer is a very popular option. When paired with a motion sensor device, you can have a potent weapon against any animals on your property. When the sensor is triggered, the device releases a burst of water in that direction. They can be sensitive enough to detect smaller animals like raccoons but they work best for deer. Just don’t have yours set up where it might pick up on pedestrians going by.

Startling Noises

Noise gadgets are a bit more varied, and you can use unexpected sounds to startle deer. Not as effective as a sprinkler but possibly easier to put in place. Sonic devices can be plugged in near your home to emit a constant high-pitched noise that deer will be irritated by is one example. A motion sensor can be used with a noise-maker to emit a sudden loud noise when they approach, or you can even just try a large wind chime to make constant noise when the breeze blows.

Electric Shock

Not quite the same as the electric fence, you can use individual shock devices to convince deer that your yard is dangerous. Several baited stakes are placed around the property, designed to give an electric shock when touched (usually using static electricity). They don’t create a barrier or border like an electric fence does. The idea is that once they get a shock, they will think twice before trying to eat anything else nearby.
