Come on Donny, . . . how about your audience? You gonna let "them" suffer?!
Just turn up the music a little more and get the crowd dancing and no one will hear a thing as those buggers fry. It's either the nasty mosquitos or us afterall. Also, the zapper unit can simply be setup far enough away from the stage to not be detected or heard, yet still remain effective as any mosquitos in the vicinity will be drawn to it instead of to you onstage or the party audience. That said, here on the West Coast, because we don't experience high humity with warm temparatures like you do in tne East, probably don't experience nearly the problem with mosquitos as in most other areas of the US. I really appreciate living here in the SF Bay Area where the morning fog acts as our natural enviromentally fresh air conditioner. ahhhh.
