Mason Jar Wasp Trap

This print is a threaded to be a standard mason jar lid.  Just put some bait in the jar and the pests fly in and are unable to find their way out.  Has a convenient spot to hang the trap should you want to.  

I suggest not using sweet bait as you are likely to trap bees and other beneficial pollinators.  Something fermenting or meat.

I added the top entrances and a hanger to make it less likely that the pests will be able to see light up the hole and escape.
