Maybe there's no mosquitoes because of all the CO2?
Never really considered it before, Lin. I live along a river back in the woods and usually after a flooding period I have mosquitoes that make mowing the yard almost suicide - yet I don't seem to recall having this issue in the forge during the same time period? CO2?
I'm like Kevin, I use a fan. I stand a pedestal fan on the end of my forge bench and blow the heat sideways so it doesn't hit me in the face.
I've got those mud daubers, too, and get a dozen or so daily.
They don't seem to be very viscous, but can surely be annoying.
