I remember the way we built wasp/hornet traps in the french countryside. Take a plastic bottle of water, cut it in two (top vs bottom), invert the top so the bottle opening is pointing toward the bottom, and fill the bottom of the bottle with wine.

Wasps and hornets are attracted by the wine, get in easily, then get drunk and apparently can't find their way out through the narrow bottle opening and die drowning in the wine.

Well I guess not those ones.
