Motion-activated water sprayers emit a short, sharp burst of water and the combination of the sudden unexpected noise, movement, and water spray scares the living daylights out of raccoons as well as many other critters and dogs and cats. Multiple units can be linked together to create a formidable barrier.
The devices require: a clear field of view (bushes and trees block
it) and a dedicated water hose line. An infra red motion sensor works day and
night to keep out intruders without chemicals or unsightly barriers. Each unit
uses only 2-3 cups of water per burst of spray. Specifications. Watch the Scarecrow at work below
