I got those things at Home Depot. I feel like a charllotan telling how good they worked but honest injun , they worked good.
As it turns out I was in Tenn at the time. You got that right about the big things coming out at night. It seems the blacker the night the bigger the bug haha Nothing like a 4 inch moth fluttering around in your helmet. Gotta make sure you keep your mouth shut or they will fly right in,,,especially if you have bad beer breath
These things don't work as well up here in Minn with the moskeetos. These have evolved into almost as bad a bee stings and almost as big. The tig welder sounds like a mig when they swarm in haha. Try to make a nice weld with a swarm of swamp moskeetos around sometime.
