Several questions are coming in about the Asian giant hornet (a.k.a. “murder hornet). To date, it has not been detected in Montana.

The Montana Department of Agriculture has set up vinegar and orange juice traps to monitor for any potential introductions (also in 2020). The design of the traps is based on what the Washington State Department of Agriculture has used in their sampling efforts.
