Invasive Ash Borer




The Minnesota Department of Agriculture announced the discovery of an emerald ash borer infestation (EAB) in St. Paul, the first detection of the destructive tree pest in Minnesota.

EAB is an invasive beetle that attacks and kills ash trees. Its larvae kill ash trees by tunneling into the wood and feeding on the tree’s nutrients. Since its accidental introduction into North America, EAB has killed millions of ash trees in 10 eastern states. With an estimated 900 million ash trees, Minnesota is a prime target for EAB.
Residents have been advised not to transport firewood, even within Minnesota. Don’t bring firewood along on a camping trip. Buy the wood you need locally from an approved vendor. Don’t bring extra wood home with you.

Don’t buy or move firewood from outside your area. If someone comes to your door selling firewood, ask them about the source of the wood.

TO TEST FOR INFESTATION ODD SHAPED OBJECTS THAT YOU SEE IN THE TOP PHOTO ARE SUSPENDED FROM THE TREE. THE BEETLES ARE ATTRACTED TO THIS COLOUR, AND THE STICKY SUBSTANCE WILL TRAP THE CRITTER, GIVING THE HOME OWNERS AND DEPT. OF AGRIGULTURE EVIDENCE OF INVESTATION. THE SMALL PHOTO IS A SIGN ATTACHED TO THE TREE TRUNK.

  2. Some insects, like bees, seem to be missing, too many of others! The balance in nature is difficult, especially when man interferes!

  3. Sound advice. Thankfully we no longer burn our fireplace. Will have it converted to natural gas. Best for the trees and our atmosphere.

  4. We get pine beetles down here. They have also been wiping out a lot of trees down here. We have already removed two from our yard, which was really sad b/c they were big old ones.

  5. Sad news, hope the funny looking traps work in time or better remain empty.
