Help! japanese beetles on bluberries.
Hello. I have twenty two high bush. And this year they really starting to produce. Only problem, they are being eaten buy Japanese beetles. I put down miky spore 3 years ago. It made no difference. In fact there were more. This past spring I put down grub-ex. hasen't made a difference. I put up some bait bags. that did nothing. I sprayed the bushes with jacks dead bug yesterday morning and this morning they are back as strong as ever. Whats next? dynamite?. any help would be a blessing. Filix.
