EAB found in Martin County

Jeffrey Hahn, Extension Entomologist

The Minnesota Department of Agriculture (MDA) reported earlier this week that emerald ash borer (EAB) was confirmed in Martin County in the south central area of the state on the Iowa border. Because the nearest infested areas in either Minnesota or Iowa are several counties away, the infestation is the result of someone moving infested ash into the county.

EAB was first found in Minnesota in 2009. Since then, it has spread and is now found in 16 counties.  EAB is a very destructive invasive insect that threatens all native ash in the U.S. Ash is a very important resource in Minnesota where about 1 billion ash trees occur, one of the highest numbers of ash trees in the country.

People can greatly reduce the chance for EAB to spread by buying their firewood locally and avoid transporting it. Burn it where you buy it. It is equally important to observe any quarantine restrictions for the movement of any ash products that may occur in your county. Be aware of the symptoms of EAB and report any suspicious infestations to the MDA’s Arrest the Pest line at 1-888-545-6684 or
