LANSING, MI (AP)-- The tree-killing emerald ash borer has made its way to the Western Upper Peninsula.
Contractors working for the U.S. Department of Agriculture placed 122 traps this year in five U.P. counties where the ash borer wasn't known to exist. A trap in Baraga County tested positive.
Baraga already had been added to a list of counties covered by a state quarantine that limits movement of firewood and other items that could carry the bug. Also added this year were Dickinson, Marquette and Menominee counties.
The quarantine covers the entire Lower Peninsula.
Travelers are urged to only use local sources of firewood, burn what they buy and not take any unused firewood elsewhere.
The ash borer has killed tens of millions of trees in more than two dozen states.
