You’ve created the lawn of your dreams; now protect it with the Hydro-Rain 62100 Yard Enforcer Motion Activated Impact Sprinkler on Spike. The motion detector sprinkler will protect your trees, plants, flowerbed, and veggie garden from uninvited guests such as deer, rabbits, squirrels, mice, rats, birds, cats, and dogs. A motion activated sprinkler is the most humane wildlife deterrent on the market and can be safely used even if your unwelcome guest is a protected species. Determine if you want the motion sensor sprinkler to run only at night when visitors are more likely to appear in your yard, daytime only, or be on constant guard. A loud burst of sound followed by a spray of water will startle but not harm wildlife and is a safe method to shoo them away.
