Community Action is key in helping to control the spread of invasive insects in Michigan. We can all play a role in keeping these pests under control.

Removing and destroying Spotted Lanternflies is a crucial step. Officials ask you to crush nymphs and adult Spotted Lanternflies when you see them, or scrape egg clusters into a plastic bag containing hand sanitizer or rubbing alcohol to kill them.

Before you head out, make sure to check your vehicles for any signs of Spotted Lanternflies. This includes checking for eggs or attached insects, and keeping your windows and doors closed to prevent them from getting in.

If you do find a Spotted Lanternfly or its eggs, document it by taking photos and sending them to the Michigan DNR with your location. This helps them properly log where the insect is spreading.

By taking these simple steps, we can all contribute to the effort of keeping invasive insects under control in Michigan.
