Make sure to set the traps far away from the tree. 30ft or more otherwise you're just attracting more!

MilkySpore really is the ticket. It takes a year or so to really see the results but works wonders. I went from decimated beans and hop plants 2 years ago to only ten beetles in the traps this season. Worth it's weight in gold even if you aren't going for organic. Make sure to place some underneath the traps to kill of any grubs that hatch there.
