It will also catch (and is very much used as) a yellowjacket trap. I use a touch of apple cider vinegar (with the mother, it's healthier
) with the oil that I put into my beetle jails...I've been thinking about adding just a tad of banana. Banana, vinegar, sugar, and water will catch the moth and yellowjackets...not sure about beetles, though, seems like it would.
Scott, I had a couple of good banana sandwiches for lunch and then went and played with (another) swarm (from my own hives). I then videoed a bunch of young bees that suddenly emerged from my two big hives and started orienting...I (the newbee) thought two more swarms were starting! Thankfully, I called my mentor and he calmed me down.
Anyhow, there wasn't a bee in the cloud of bees I was working in that seemed to mind banana breath.
