You can certainly use VespaCatch attractant (available in 1L bottles or 10 ml single-dose sticks) specifically designed for the Asian hornet, which has been proven effective in numerous tests.
Since VespaCatch Select is a non-drowning trap, you can also use a protein-based attractant (such as shrimp or fish pieces) in summer when Vespa velutina workers are more attracted to proteins and less to sweet attractants.
