Push beetles in a glass of soapy water, go out every night a few times. Or spray Captain Jacks Dead Bug Brew. It might work? Labeled for some beetles, but not June Bugs. It's Organic, It is Spinosad. Another organic for Japanese Beetles is sold only at Garden's Alive for now. It's a strain of BT bacteria, that probably will work. They eat Chitin. Will eat grubs too. These methods are all super safe and can even be sprayed on figs. Wait 7 days if using Spinosad before you harvest fruit. Or you can go with the big guns, follow label directions. Anything safe to spray on fruit, follow all directions on label, when to harvest etc. Bonide's "Eight" is a fairly safe product that will work. It's a Permethrin, which is based on an organic, but is a more effective synthetic.
