LANSING, Mich. (Great Lakes News) – A proposed firewood quarantine is designed to keep pests out of Michigan.

Michigan’s Department of Agriculture and Rural Development has proposed a quarantine on exterior firewood to help prevent the introduction of unwanted pests and diseases.
Under the proposal, firewood shipped into Michigan would have to be certified as heat-treated at a temperature of 140 degrees Fahrenheit for at least 60 minutes.
Kiln-dried lumber and wood chips smaller than one inch and logs or wood shipped from out-of-state sources directly to mills and other facilities for immediate processing would be exempt.
