I'm looking for a meshing material that fruit flies won't get through, but one that will allow for ventilation to pass through. Something that is made of plastic/vinyl or whatever would be preferred over metal mesh.
I have mesh now, but it's so fine that sometimes water closes the openings and I have a wet mess that doesn't let air through.
You can post links or if you have a lot of it, I'll gladly take/buy some off your hands.
