Mason Jar Wasp Trap

I Saw a few similar ones on here for flies, but our problem here is wasps, i also adapted it to be able to have a string run through it so it could be hung from a tree...

EDIT: I just added V2, i found V1 did work, but it wasn't a smooth and a little tighter on the jar than i wanted. I recently learned how to do threads, so i recreated it entirely around the threads i found worked well on the jar, so V2 is a complete rebuild from the threads out, i think it fits a lot better.

EDIT again
