Interesting, gets the wheels turning as to "does it work?"...
Never used a trap like that before. Seen 'em, but never really looked at it. I thought the concept was the beetle stays trapped because its in a bag. If the bag wasn't on there, wouldn't a good majority just start to fly away as they drop?
...and as a kid, I remember trying them as bait, like everything else I could get my hands on took a dunk for experimenting. Never continued doing so, I'm guessing because it wasn't the best option.
It will be interesting to see what others may think.....
