Japanese beetles are new to my particular area- although I was familiar with them in my grandfather’s garden. Back then it was a manageable task to hand pick them and drop them in a jar of kerosene ( my job). This infestation that i’ve experienced the past two years has been an unbelievable plague. They cover full grown cherry trees and decimate the leaves…then move on to about everything else. They also love the hazels. You couldn’t possibly hand pick them off when the numbers are so outrageously large, but the bags have been a help. In our case it isn’t such a problem when many gardeners in the area are using these bags.
We let them fill up and them dump them in the burn pile, reusing the bags. A smelly mess…. but hopefully over time it will help reduce the numbers. I wanted to get the bacilli and milky spore… but the sotres all sold out last year. This year I hope to get some and use everything in the arenal against them.
