How does it work?
The ScareCrow uses a combination of sudden noise, unexpected movement, and a startling blast of water to create a memorable and unpleasant experience for the trespasser.
The animal immediately associates this unpleasant experience with the location, and to avoid similar surprises, learns to avoid the area. If an animal chooses to return, the ScareCrow will be waiting.
While a human may flee several steps after activating a ScareCrow, animals are typically affected to a much greater degree. In most cases they run much farther, and stay away longer. Because the unit only triggers when the animal moves, its behavior is difficult for animals to anticipate, making it a very effective deterrent.
