Important Information About EAB infested firewood


If you have an EAB-infested tree that you would like to use as firewood, be aware that EAB can continue to emerge from the wood for two years after cutting. To avoid spreading EAB, split and leave the wood to age near where you cut the tree for two summers. After two years of drying, EAB that may have been within the wood will have emerged or died. The aged firewood poses little risk of introducing EAB and you may move it freely within the limits of the quarantine.

Emerald ash borer and firewood restrictions
State and federal laws forbid moving hardwood firewood out of emerald ash borer quarantined areas. 

Currently, this means hardwood firewood that has been stored, purchased, or harvested in the following areas may not be moved out of these areas in Wisconsin: Adams, Brown, Buffalo, Calumet, Columbia, Crawford, Dane, Dodge, Door, Douglas, Fond du Lac, Grant, Green, Iowa, Jackson, Jefferson, Juneau, Kenosha, Kewaunee, La Crosse, Lafayette, Manitowoc, Marquette, Milwaukee, Monroe, Oneida, Outagamie, Ozaukee, Portage, Racine, Richland, Rock, Sauk, Sawyer, Sheboygan, Trempealeau, Vernon, Walworth, Washington, Waukesha, Winnebago and Wood counties. A federal quarantine also prohibits the movement of hardwood firewood out of all or parts of more than a dozen other states and parts of Canada. This map shows the most current national and international quarantines.

Quarantine Violations
If firewood from a quarantined county enters a DNR managed property in a non-quarantined county, regardless of whether it is within 10 miles, it will be confiscated. State and federal fines up to $1,000.00 apply for violations of firewood quarantines.
