If you have a garden, the only truly effective animal deterrent is to scare them away. This is easily done with water. How it works? With a spray that shoots towards the intruder that crosses a motion sensor. Take a look at this demonstration video of the Contech Sprinkler in action.
The response is very quick and the movement and sudden spray of water never fails to scare animals off. It simply works every single time on all kinds of animals such as deer, squirrels, raccoons, wild pigs, cats and dogs, and even birds.
This is a eco friendly and humane way to scare animals off. All it uses is water. No chemicals. This is a very cheap animal deterrent considering the range it has and how effective it is.
