I meant to report back on this a while back, but I forgot about it after I got rid of the problem.
I found the ultimate gnat zapper. You guys offered some good solutions, but they have to be re-done, renewed, refreshed, and every time I go out to bring in the mail, more gnats follow me back in.
As Jimi pointed out (as do many online sources) gnats hate peppermint. I've never vaped mint flavors, never did smoke menthol, none of that, but for gnat patrol I ordered a bottle of peppermint eliquid at my usual nic and pg/vg levels. I have a dedicated tank for it, which I keep at my desk, and when a new gnat starts dive bombing me, I switch tanks from my clove to this peppermint, and done. Gnat executed, can't escape the cloud.
I hope this will help someone else.
