Rob,
Just bought an aerosol can of "No Stinkin' Bugs". It is supposed to be scent free. I picked it up at Wally World for about 5 bucks. I have not tried it yet, but may do so in the back yard while shooting. I cannot believe there are any mosquitoes anywhere else in the world with all of them being in my back yard. I will let you know how it performs. The bugs in the yard are not at all put off by the stuff the wife uses on the kids. I don't think it slows them down. That being said, if this new stuff works out back, I would have to say it is pretty good. I keep you posted.
