Sending them elsewhere is not only a logical solution, it's also humane and earth friendly. They're there for a reason and killing them isn't always the best solution. Kudos to you for figuring this out!

I remember a film shoot that had been overwrought with yellow jackets and no one had thought of that brilliant idea.  I spent my lunch in motion, out running the suckers.  

The next film set I'm on will be watermelon ready!
