A thought on green Japanese beetles and moles. Apply Milky Spore.

It interrupts the beetle life cycle. It's a bacteria that gets absorbed into the soil and kills the grubs. It will stay in the soil for ~10 years.
Down side, it takes many applications over time to fully imbed. I am on my 3rd year of applying in the spring and fall. Last summer I noticed the lack of beetles. Not perfect but better than the prior year. It also needs to be watered in, so right before a rain or sprinkler. Also, not cheap. I have a large yard, 1.5 acre, and it costs me ~$300 per.
Upside, controls the beetles and MOLES. I know that moles feed on different things ie worms, but last year, not nearly as many moles. Cut their food supply and they go elsewhere.
