Correction: Not yellowjackets

Caught over 20 in 3 hours. So that worked better.

So I guess they are European Paper Wasps? The just look so....yellow-jacket-y. And I grew up with plain brown wasps.

That's the "Rescue TSW-BB6 Visilure TrapStik for Wasps," which I got at Ace Hardware, bless them.  I think I'm going to be buying these by the case.

Truthfully, it....well, obviously it caught a lot, but I saw an unusual number of wasps that appeared to be trying to find somewhere new to live. (Which is why I think I need more traps.) Hopefully I can convince them to go build their house somewhere NOT attached to our house.
