Mayflies typically begin to emerge from the Lake Erie mud beginning in June and can live for up to 72 hours.

The bugs have also been spotted recently “invading” closer to Northeast Ohio.

As annoying as mayflies are, they are completely harmless. The bugs tend to congregate under bright lights and rest on the pavement or stuck to the side of cars.
