Very interesting. What made you think of everclear?
Ethanol is very hydrophillic in a concentrated state (95% or so), such that when you spray it on the wasp I can only surmise that it pulls the water out of them, leaving them quickly unable to react.
I had the bottle of everclear as an antiseptic or a way to sanatize something, and figured it was worth a shot.

I was really wanting to kill them, not throw them a party!
Seriously, though, if it works I wonder if isopropyl alcohol would too? Or at least make them go blind!

Isopropyl works ok, though you can't get it in as high a concentration, and it's fairly toxic. Plus the fumes burn my eyes in closed quarters, which seems to be where the little buggers like to hide.
