Another infestation of emerald ash borer found in Minn.

Officials have found another infestation of emerald ash borer in Minnesota.

Survey crews identified infested trees on a couple of islands in the Mississippi River, very close to a previous infestation in Wisconsin.

The Minnesota Department of Agriculture's Geir Friisoe says public education is the key to slowing the spread of the pest.

"Our main focus now in Houston County, which has already been quarantined, is to work with the public and try and avoid any firewood movement out of that area, particularly from areas close to the river where it's likely to be infested," Friisoe said.

Both Ramsey and Hennepin Counties are also quarantined. That means people should not move ash trees, ash tree limbs, or any hardwood firewood from place to place.
