#EABweek

Illustration with the message “Buy it where you burn it,” showing logs next to a campfire and a green beetle flying through the night sky. Forested mountains line the bottom, and the site name “Don’t Move Firewood.org” is prominently displayed, warning against transporting firewood that can spread invasive pests.

🚫 Don’t move firewood—it moves pests! 🪲

Emerald ash borer (EAB) is destroying #ashtrees across Minnesota, and moving firewood spreads it faster. Buy it where you burn it to protect our forests, parks, and neighborhoods.
