Wisconsinites are trying new things to stop the tree-killing emerald ash borer
Wisconsin cities and forests are trying new things to stop the emerald ash borer from spreading.
The tree-killing beetle was first discovered in the state 14 months ago.
In Milwaukee, crews will finish spraying insecticides next year on 28,000 city-owned ash trees. The job's about half done.
Officials will then urge Milwaukee property owners to either treat their ash trees, or replace them with other varieties.
