I learned this from a wine making store in Dover, Ohio.
I put a small glass - with angles sides - like 45-60 degrees, with 1/4
inch of red wine in the bottle. These fruit flies end up in the wine and
drowning. This also works around fruit. It takes a couple days, but
works. I use like high-ball glasses with angled sides. It works, not
sure if the angle matters, but I don't experiment with success. :*)

And cockroaches - learned this from a Navy retired dude from WW II who
used it on ships and subs, mix a paste of Boric Acid powder with water -
so it's almost toothpaste consistency. put into a shallow small
container (even a plastic milk carton lid) and put on the floor several
places. Cockroaches are gone in a few days to a week. Even if infested.

That last one has nothing to do with wine making pests, but thought I'd
share - it sure worked for me in many places.

Anyone know how to get rid of squirrels from bird feeders? Just kidding,
let's stick to winemaking. haha.

not seen any in my must or secondaries, but I feel like I am playing
with gasoline inside a torchlit room. does anyone have some
suggestions? I am using flypaper right now which is catching them, but
more still apear.

not quite clouds of them, but enough to have me ask here.
