Help! We have a huge Japanese Beetle problem in our garden and orchard. Our new Cherry and Plum trees are hit bad -- they are literally consuming the top part of the tree where they sit during sunlight. They also are destroying a 10 year old Mountain Ash tree. They love my grape vines.
I've went to the local store and they claimed Captain Jack's Deadbug product would work, but after spraying the trees 2 days ago it has not. I've tried Sevin in the past and it seems to work for a few days and then they're right back. I pick them off and toss in soap water a couple times a day but I cannot keep up with their appetite.
Does anyone know what does work and what will not harm the plants/trees?
