MINNEAPOLIS (WCCO) – If you buy a Christmas tree or wreath online this year, make sure you’re not letting destructive insects into your home or neighborhood.

The Minnesota Department of Agriculture (MDA) is warning consumers that such plant products are regulated in certain parts of the country. The department is asking consumers to get proof from retailers that the trees and wreaths you seek to purchase meet all the requirements to be shipped to Minnesota.

MDA Plant Protection Director Geir Friisoe said the department is trying to prevent the spread of forest-destroying insects like as gypsy moth, sirex woodwasp and the pine shoot beetle.

To make sure your holiday plants meet all of Minnesota’s standards, the MDA says you should buy from Minnesota tree farms. You can find a Minnesota tree farm near you at www.minnesotagrown.com.
