There’s no stopping the emerald ash borer, from the looks of things. Wisconsin has declared next week Emerald Ash Borer Awareness Week to try to stop the little critter that’s killing ash trees. But it’s already ripped through Wisconsin and has arrived, reports today say, in St. Paul.
From the looks of things, efforts to slow the spread of the killer insect don’t do much good once it’s already in the vicinity. Most of the tips involve not moving firewood from one area to another. But the emerald ash border can fly about a half mile from a tree it infects.
