I've tried most of the spectrum of things for fighting the beetles from companion planting to the toxic-ist of gick, and the Japanese Beetles are un-phased by most of it.
Our netting only protects our berries from birds, which is great, but the beetles are still a problem, because they can crawl through the holes.
Last year we put the beetles into containers of soapy water. This year I will be spraying with Neem Oil and possibly sprinkling with DE and thinking of applying Milky Spore for next year.
