Beetle, identification, and tips for management #877058

Asked July 13, 2024, 9:16 AM EDT

I have these Beatles in my garden. They mostly come at night and they have decimated my sunflowers. Any help on identification of the beetle and ways to get rid of them would be appreciated

Hello Jessica
This is Asiatic garden beetle. There are some non-chemical management practices that are friendly to beneficial insects.

UNH bulletin on Asiatic garden beetle

https://extension.unh.edu/resource/asiatic-garden-beetle-fact-sheet

Insecticides labeled for Grub management are available for use in non-edible flowerbeds and lawns- this bulletin names the active ingredients of  those insecticides.

If your sunflower seed  will be saved for consumption, do not use insecticides on the plants, unless the insecticide is labeled for use on edibles such as vegetables. Please follow all label precautions and directions when using  any garden products.
