Movement of infested firewood is an easy way for insects (e.g. EAB) and disease (e.g. oak wilt) to be Introduced into noninfested forests.

"Don’t move infested firewood" and proper wood disposal have been key messages for some time in the management of Dutch elm disease, oak wilt, pine bark beetles and a number of exotic wood boring insects. All of these pests, and many others, can be moved from one place to another in raw wood products -- including firewood. Until recently, these messages have not been overwhelmingly received. However, with the continued spread of the emerald ash borer and its apparent association with the movement of firewood, many homeowners who cut/burn firewood, and land and forest owners, are taking heed.

Here are some things to remember when it comes to firewood and proper wood disposal:

• Cut and split wood to be used later on site. Avoid moving infested wood off site whenever possible.
• If you do move firewood from the woods to your home, dispose of all infested wood by April 1st of the following spring. Debark, chip, burn or seal with a plastic tarp all infested wood before pests emerge from their winter sleep.
• If you bring firewood along on a camping trip, be sure to burn it ALL before returning home. Do not leave it for the next camper.
• Whenever possible, buy firewood that was produced, not just purchased, locally. Be aware that many large distributors repackage their firewood so it may not list the state of origin.
• If you run across firewood coming from an infested area, ask if it has been certified pest free. The distributor should have papers demonstrating that they are in compliance with state and federal regulations.
• Monitor trees under your care for signs of infestation. Both the emerald ash borer discovered in Detroit and the Asian long horned beetle discovered in Chicago during the 1990s were found by concerned citizens and not by professionals.
