Jo Ann, what brand is the new spray you are trying? I agree, applications of the foliar spray need to be applied frequently. I was trying to spray at least every two weeks, but as soon as I missed a re-application the deer were at my plants in a heart beat. I read that applying multiple sprays in a round robin schedule helped deter them from getting used to any single spray. That part seems to work for me, only having trouble when I miss a re-application in a two week timeframe. I've been using three sprays - Bobex, Deer Off, and Deer Away. The systemic pellets that my gardening friend recommended is Repellex
