Michigan's 2027 Firewood Quarantine: A Trust-Building Topic for Tree Companies

Michigan's environmental agency (EGLE) used Firewood Month to remind residents not to move untreated firewood. Wood carries insects and diseases with it, including emerald ash borer, oak wilt and spotted lanternfly.

The key dates

• A firewood certification program started in Michigan in 2026.
• Beginning Jan. 1, 2027, an external quarantine means only heat-treated, certified firewood may be brought into the state.

What it means for tree service owners

If you sell firewood, haul wood, or take in logs from jobs, check the quarantine rules before 2027 so you are not caught out.

It also hands you a content topic homeowners care about. People who hear "emerald ash borer" or "oak wilt" want to know whether their own trees are at risk, and they tend to trust the local expert who explains it clearly.

Content ideas

• A short guide: "Is my ash tree at risk?" with signs to look for and when to call an arborist.
• A seasonal post on why firewood should stay local.
• A short video of your crew explaining what an inspection involves.

Rules differ by state, so check your own state's agriculture or natural resources agency before publishing anything specific to your area.
