Mosquito Repellant shield. I found this on FB last year and put it to the test. Sure enough, it works. I placed half of line wedge with whole cloves in window ledges Inside my home, and created a barrier outside in the area we sit on Summer nights. This repellent works immediately and i did not have to replace the limes often. I reused each clove after the limes dried out. I'm hooked on not getting bit by the Mosquitoes with this most frugal and fab natural repellant!
