Instead of stressing over how to keep pesky critters off your lawn and out of your gardens, invest in the SCARECROW MOTION ACTIVATED SPRINKLER ($79) from Contech Electronics. The device offers a humane way to keep whatever friendly visitors you might have — cats, dogs, rabbits, deer, or large birds — out of your carefully tended gardens. The motion-sensitive Scarecrow attaches to a common garden hose and senses the movement of the unwanted critters. Then, it unleashes a three-second spray of water toward them. After being doused a few times, it’s unlikely that your little intruder will return. (800) 767-8658 or
