Keep animals away from your pond or garden with a harmless blast of water. Protect your yard, fruit trees, vegetables, flowers and water features from hungry or destructive animal intruders. The ScareCrow motion-activated sprinkler automatically detects deer, racoons, heron, dogs and more as they approach, and repels them with a short but startling burst of water. The sudden noise, movement and spray scares animals away, teaching them to avoid the area in future. The ScareCrow: Works day and night without chemicals or unsightly barriers Can be linked to other ScareCrows to form an effective water barrier Conserves water – uses just 2 to 3 cups per deterrence Operates for up to six months on a single nine-volt battery One scarecrow covers approximately 1200 sq. ft.
