Beemiester asd "are you catching many European Hornets in your trap?"
Not a lot but ever dead one sure looks great. On a good day I only get 3 or 4 per trap.
The best lure for the European hornet that I have seen is the apple flavored jolly ball that I hung for the horse. Once the hornets found it there would be 10 or more of them at any one time. Needless to say the horse ignored it. However, this required the ball bat approach.
