Minnesota agriculture officials are encouraged by the initial results of a new way to find emerald ash borers. The Minnesota Department of Agriculture recently finished the first year of a three-year study to detect the destructive tree pest.
The destructive emerald ash borer has been discovered in trees near St. Paul's historic Summit Avenue. The pests were discovered earlier this month. The area is three miles away from a previously infested spot in the St. Anthony neighborhood.
Researchers will be hanging thousands of purple traps across Minnesota this summer in search of the emerald ash borer. The Minnesota Department of Agriculture plans to place 4,500 traps starting this week.
