How to control the avalanche I have with the Japanese and June beetles without damaging the bees and bumblebees on the roses and rose of sharon bushes? I have killed hundreds of them practically by hand. (I place a strong insecticide and water on a plastic container and with a stick I shake the twig making the bug fell into the container) but it is getting to be full time job as more arrive in no time. Thanks a lot,
