Sounds really bad. I have used those Beetle traps and hubby squashed them. I think he may have also washed them off with the hose and then drowned them.
The are really only bothering my rosa rugosa plant and we don’t use rose hips that often, so it was more of a pretty hedge type plant that we planted as an experiment. It has pretty roses.
We are going to have to go squirrel hunting - the jerks got all the apples before they were even beginning to ripen. Hubby didn’t think anything would bother them till they were closer to ripe and so he didn’t cover them.
So, the beetles haven’t bothered the apple tree leaves? Mine look like lace.
