Ohio is one of three states, along with Massachusetts and New York, with quarantine regulations attempting to control the spread of the Asian Longhorned Beetle. The other 47 states are also at risk from this destructive insect that has destroyed 80,000 hardwood trees in the U.S.

Trees at Risk

asian longhorned beetleIn Ohio, the Buckeye tree is at risk as well as the state’s multi-billion dollar nursery industry. It’s estimated the beetle has already affected seven billion board feet of maple wood alone and is affecting maple sugar processors.

Once the Asian Longhorned Beetle infests a tree, there is no cure. The beetle bores into the heartwood of the tree where treatments can’t reach. The adult beetle is most active during summer and early fall.
