If you're looking for a safe, effective, and low-maintenance animal repellent, Scarecrow Motion-Activated Sprinklers are a good option. All you need to do is assemble the sprinkler, hook it up to a hose, and place it near the area of your lawn that you'd like to protect. These sprinklers keep pests away with little worry or effort on your part. And unlike traps, predator urine, poisons, etc., Scarecrow Motion-Activated Sprinklers are set up just once and control a broad spectrum of pests. This device will safely deter a variety of animals like deer, dogs, cats, and squirrels.

  • Scarecrow Sprinklers are safe for people and pets.

  • Scarecrow Sprinklers are humane: pests are simply driven off, uninjured.

  • Unlike animal repellents like predator urine, there's no "re-application" with Scarecrow Sprinklers.

  • Versatility: no need to take separate control measures against each of the various types of pests.

  • Scarecrow Sprinklers will work as long as they sense motion. They will continue to shoot out water at 7-second intervals until the pest leaves.

  • Requires a 9-volt battery (sold separately).

  • Scarecrow Sprinklers may get you wet if you're not careful.

  • Some users had trouble with a leak where the stake meets the hose. Usually this can be remedied with some minor adjustments.

  • Requires you to keep your hose on, which may mean you need to instal a second hose if you want to still be able to water your plants.

General Review - Scarecrow Sprinklers

The principle behind Scarecrow Sprinklers is simple enough—a motion sensor lurks within the "crow's head" sensor housing that is constantly on patrol for pest. Just as with motion-activated lights, anything that crosses the sensor's path activates the device—except that, instead of beam of light, the Scarecrow sensor activates a shooting stream of water. The water is shot directly at the pest, scaring it off.

A sprinkler head sits atop the sensor housing, which, in turn, sits atop a stake and a stake extension. The stake is jammed into the ground. The stake extension is hollow and forms a "T." One end of the T's crosspiece hooks up to a garden hose. The other end is sealed with a flow through cap, unless you wish to attach a second hose (for watering) or wish to install multiple Scarecrow Sprinklers. The fact that you can attach a second hose meets an objection some might raise concerning the Scarecrow Sprinkler—while it's running, you're unable to water your plants.

Best practices for regulation of Scarecrow Sprinklers:

  1. Make sure your water pressure complies with the suggested pressure indicated on the directions.
  2. Adjust the arc of the spray coming from the sprinkler. This is done by changing the position of stem tabs on the sprinkler unit.
  3. Check the knob on the sensor housing that determines the sensor's sensitivity.

Regulation is fairly intuitive and just requires a bit of practice and consistency. Your system should work for many years if you make sure it's running as it should.
