Gypsy Moth Quarantine and Regulatory Information

Gypsy moth is a serious invasive forest pest that requires a quarantine to slow it's spread. The gypsy moth quarantine limits the movement of certain items out of a designated area and is an effective tool in managing and slowing it's spread across the U.S. and Minnesota.

Gypsy moths are expert hitchhikers and are most commonly transported as egg masses. The female will lay her eggs on any solid surface increasing the risk of further distribution.

The following articles are regulated under gypsy moth quarantines

  • All stages of the gypsy moth life cycle including: eggs, larvae, pupae, and adult moths
  • Logs, posts, sawbolts, and pulpwood
  • Bark and bark products
  • Nursery stock
  • Christmas trees, boughs, wreaths and garland
  • Firewood
  • Outdoor household articles
  • Mobile homes and associated items
  • Any other products, articles, or means of conveyance that present a high risk of artificial spread of gypsy moth
