Japanese beetles and honeybees

Asked August 6, 2018, 3:19 PM EDT

Every summer we have Japanese beetles that destroy our roses and apple trees this time of year. This year we have a hive with honeybees and we want to ensure a bee-safe solution to the beetle problem. Are there any effective options? We live in downtown Stillwater in a small plot.

You can try manually knocking the JB's into soapy water early each morning and late in the day. They move very slowly then. Although I just knocked a couple dozen into a cup of soapy water off basil on my deck at 3:00 in the afternoon. Another person who had this problem shared that she was gong to cover her rose blooms with plastic bags and then spray the leaves with an insecticide. She could then remove the bags after the product dried. Bees will visit the blooms but JB's eat the leaves. Here is a link to our publication on JB's. Maybe it will give you some ideas: https://extension.umn.edu/yard-and-garden-insects/japanese-beetles
