I must say for the past 4 years we have been fighting deer! We have tried different sprays, little bags, scarecrow sprayers, and soap…this year I discovered Nite Guard Solar! OMGosh! Our gardens have never been sooooo beautiful! Before Nite Guard Solar a section of my tulips were taken care of by the deer. I purchased 4 Nite Guard’s and had such success we ordered 4 additional ones. We have 5 gardens. We have given Nite Guard Solar to SEVERAL of our neighbors and friends and told them it was definitely worth the money invested! Thank You!
