Grasshoppers are the #1 pest at my location (well, other than deer). I grow strawberries, blueberries, blackberry. raspberry and a few fruit trees. They love to eat strawberry leaves. Best thing is Sevin. Kills em by the hundreds. Problem is it only lasts for 4 or 5 days and your not supposed to do back to back applications and your only supposed to use twice in a season. Imidacloprid was good but it has been linked with honey bee collapse. So I don't use it anymore.
