MARSHALL, Minn. — The emerald ash borer has been confirmed in Lincoln and Pipestone counties.
The Minnesota Department of Agriculture says the insect was found at a campground near Lake Benton and at a yard waste site in Jasper.
The larvae kill ash trees by tunneling beneath the bark and feeding on the tissue that carries nutrients. Officials say early signs can include increased woodpecker activity and light-colored patches, known as “blonding,” on the bark.
Some healthy ash trees can be treated, particularly within 10 to 15 miles of an infestation. Officials also warn that moving ash wood and firewood can spread the insect.
An emergency quarantine is being established in Lincoln and Pipestone counties, restricting the movement of firewood and ash material. Minnesota has now confirmed emerald ash borer in 62 counties.
