Hang a piece of chicken 6-12" over a bucket of soapy water. The wasps will leave you alone to eat their chicken. When they've had their fill, they will try to fly away. Since they've never been so full before, most of them will miscalculate the energy it requires to take off with that much load, and into the bucket they go.
Or if you're like me and you have a small unused shed completely infested with these little winged demons you light the d*mn thing on fire and walk away then laugh about it. Thankfully I'm not allergic to them.
Once you here the simple tap of a wasp landing, the game begins
Objective: Find the wasp before it finds you
