The Minnesota Department of Agriculture (MDA) is encouraging residents who purchased wreathes, swags, boughs, and other evergreen decorations at several retailers to burn items, or bag and throw away items to stop the spread of the invasive insect elongate hemlock scale (EHS).
EHS is native to Asia. It feeds on nutrients found on the underside of conifer needles.
Earlier this week the Wisconsin Department of Agriculture, Trade, and Consumer Protection issued a similar warning after finding EHS in greenery at several retail chains. The MDA then began inspecting similar retailers across Minnesota, looking for the insect in any leftover greenery. The Minnesota Department of Agriculture found the insect in displays at Menards and Home Depot locations. Both companies are cooperating with MDA investigators and are pulling what’s left of the displays off the shelves.
The bigger challenge for inspectors is the evergreen items came all the way from North Carolina. It’s more than possible that the items were sold at other locations as well.
Minnesotans who bought wreathes, swags, boughs, and other evergreen decorations at Home Depot or Menards should burn the items, or bag them and dispose of them in the trash once the items are no longer useful for decoration. Do not compost the items.
“Unless you know you purchased evergreen products from a locally grown source, residents should err on the side of caution and burn, or bag and throw away your evergreen items,” said Assistant Agriculture Commissioner Whitney Place. “This will help us ensure this invasive insect does not get a foothold in Minnesota.”
Elongate hemlock scale has been found in the eastern U.S., Michigan, and Nevada. It had previously not been found in Minnesota.
