Sate officials are asking Wisconsin citizens to join the fight against the Emerald Ash Borer.
Governor Scott Walker named May 19-25 Emerald Ash Borer Awareness Week.
Officials hope to spread information about how people can help stop the pests from killing ash trees.
13 Wisconsin counties have trees infected by the emerald ash borer, including La Crosse County.
Officials say a major way to help stop the spread is by making sure you don't move firewood out of the counties infected with the borer.
