State To Release Wasps To Fight Emerald Ash Borers

ST. PAUL, Minn. (AP) — Officials are planning to release stingless wasps near St. Paul’s stately Summit Avenue to combat a newly discovered infestation of emerald ash borers.

The stingless wasps are one of the few natural enemies of the emerald ash borer in their native Asia, so the Minnesota Department of Agriculture plans to release them Friday afternoon as part of a broader pest management plan. Other weapons include removal of infested trees and treating trees with insecticides.

The emerald ash borer has killed millions of ash trees in other states and threatens close to 1 billion trees in Minnesota. The metallic green beetles were discovered in St. Paul in 2009 and have spread to Minneapolis, Falcon Heights and Shoreview. They’ve also turned up in Winona and Houston counties of southeastern Minnesota.

    I thought they did this months ago Why do it just before winter, then have to do it again in the spring. Isnt that a waste of money.

    Wonderful! The snootys over on Summit get the problem fixed but the rest of the effected areas get nothing.
