Scarecrow Sprinkler - Repel Large and Small Animals From Your Yard and Garden

Updated on May 27, 2013

Garden Pests

Getting rid of deer, raccoons, cats, dogs, birds, possoms, rabbits, or even the lowly armadillo from your garden space can be a real challenge. Doing this without poisons or other harmful products just adds another layer of complexity to the problem as well. Here is a gentle, peaceful, and possibly entertaining! way to get rid of your garden pests.

The Contech Scarecrow Sprinkler

One product that gets a lot of favorable reviews is the Contech Scarecrow Sprinkler. This product works on almost any larger garden pests, and does it without hurting them or harming your garden or lawn in any way.

The concept of the Scarecrow Sprinkler is simple enough. We all know that if you were to spray the garden hose on almost any garden pest like a dog, cat, or bird, it would immediately move away from the water spray.

This sprinkler takes that basic concept and just automates it. Using an ultrasonic detector (similar in concept to the one that operates the automatic lights on your outdoor garage lights), it senses the motion of pests in your garden or lawn, and shoots a short burst of water (it lasts just a few seconds) over the area you cover when you set it up, and away go the pests. The moisture, noise and movement combine to startle your unwanted visitors away, but leaves them unharmed.

The video below shows how it worked on a spa that continually had problems with birds leaving droppings. It's battery operated (standard 9 volt), so you just need a garden hose to hook up to the sprinkler.

The battery on the Scarecrow is suppose to last for several thousand activations, which should be measured in months, and you can cover up to 1000 square feet (about 35 feet out from the sprinkler, with a 100 degree sensor zone).

It has been used to repel the usual suspects like cats, dogs, deer, chickens, rabbits, birds (including herons), raccoons, possums, and armadillos. I'm sure it will work on small children at times!

In fact one common complaint is that it does work on humans, and it's easy to forget it's on and therefore walking into the protection zone you become wet.

Some folks claim that the pests learn to stay away after a few weeks, and you can actually move it to protect another zone while they stay away from the first one.

Check out the Amazon reviews. This works very well for a lot of gardeners, it may work for you!

A Tip on Installation

One trick to setting the Scarecrow Sprinkler up correctly is to be sure the hose is tight in the connector, and you may want to use a little teflon tape to make sure it's water tight.

Alternative Infrared Sprayers

Havahart has recently started shipping their version of a sonic sprayer. The reviews on Amazon seem to be relatively positive. The biggest complaint is that with very small animals sometimes the sensor isn't triggered. Overall people seem to be happy with it.

What's your favorite way to get rid of garden pests?

      "These are great ideas for keeping garden pests away. Have you ever tried any repellent sprays? I found this repellent called Deer Off II while searching online.

      It's supposed to last up to 3 months."

      Cool idea. I have a terrible time with very young plants and starting seeds. The rabbits eat everything. Maybe something like this sprinkler would save my baby plants.

      I gave one of these to my father last year and he thinks it's great. Like everyone he's been sprayed by it a couple of times, but its kept the raccoons out of the garden.

      My next door neighbor is a landscape contractor who specializes in installation of garden ponds. His home is surrounded by ponds filled with expensive fish. We live adjacent to a river and many native animals take shelter on the banks of the river. The wildlife decided that it was easy to feed off the fish in my neighbor's ponds a few years ago.

      The installation of a couple of carefully placed scarecrow sprinklers instantly ended the problems he was having with loosing fish to the predators. I do get sprayed from time to time when I work on my own vegetable garden but, that is most often a refreshing surprise. This is a timely Hub, Thanks John.
