>Some years ago I suggested that the lure used for wax moth control (see our article on wax moth) might 'attract' the flying beetles, and did suggest that the wax moth trap could be adjusted to bait the flying beetles when they emerge from the ground. Unfortunately not having a problem with SHB as they haven't reached our area yet, I could not test my theory, but can now report someone has done so.
Mel and Sonny, the experimenters took small containers, individual sandwich containers, punched 3/16th holes through the side, filled the bottom with Food Grade Mineral Oil, then in the centre placed a half filled bottle cap with wax moth lure, then replaced the sandwich container lid. This after a great deal of experimentation 'baits' the trap into which the SHB are drawn, they fall into the FGMO and are killed.
>Method.
Wax moth lure as used by Mel and Sonny. Take 1/2 cup Apple Cider vinegar,1/4 cup sugar, 1 cup water, 1 ripe banana peel, cut up finely, combined and allowed to ferment before adding small quantities to the trap.
