The shiny, metallic-green beetles chewing your roses into lace right now are invasive Japanese beetles, and they've only just begun to party this year.
They emerge from the ground over the next few weeks, and they don't let up for about the next month and a half.
Here's the thing that makes them spread: a beetle feeding on a leaf releases a scent that calls in more beetles. A few become a swarm, which means the single best thing you can do is cut that signal off early.
Go out in the cool of early morning, when they're slow and clumsy, hold a cup of soapy water under a cluster, and tap. They drop right in.
They can't bite you, their jaws don't break skin, so you can pick them off by hand too. Ten minutes a morning for a couple of weeks genuinely thins them out, because you're pulling the beetles before they call in the reinforcements.
What you should not do is buy one of those bag traps. They work by scent, a floral lure plus a synthetic copy of the female's mating pheromone, and they are extremely good at it. So good that they pull in far more beetles than they catch, from your yard and your neighbors' yards both.
And if a skunk has been digging little cone-shaped holes in your lawn at night, it isn't vandalizing the place. The grubs that turn into these beetles are down in your soil eating grass roots, and the skunk is doing your pest control for free, one grub at a time. Let it work.
