This innovative animal repellent is practical and robust, designed for outdoor use. It is a humane, non-toxic and highly effective way to deter unwanted animals including cats, squirrels, herons and other pests from vulnerable areas in your garden. This innovative sprinkler is powered by 2 AA 1.5 V alkaline batteries (not included). As soon as the built-in sensor detects movement within a range of up to 10 meters, a water jet is quickly activated. To maintain sensitivity, clean the PIR lens occasionally with a damp cloth. Thanks to the high-quality components, this animal repellent sprayer is very durable. You can easily place the sprinkler in the garden by inserting the ground pin into the ground.
