The Malibu solar-powered mosquito inhibitor does what repellents can't: it blocks the mosquito's ability to track your scent by using the patented chemical Linalool that was developed in cooperation with the USDA. Linalool was found to be twice as effective as DEET and many times better than Citronella oil at preventing mosquitoes from homing in on human scent, blocking mosquitos up to 100 feet. Retake control of your yard and enjoy the outdoors without being eaten alive. Solar rechargable batteries come installed in the mosquito inhibitor, simply turn the switch to the "on" position for hours of mosquito protection. This model also features a soft amber light for those lovely bug free summer nights!Features Include:Blocks mosquito's ability to track human scent Solar powered-easy to use Soft amber light Protects up to 100 square feet 1 year limited warrantyRechargable batteries included9 x 9 x 9 inches
