Will this cover prevent tiny gnats from entering drainage system?
Camco 42152 Flying Insect Plumbing Vent Screen
We have a septic system and at certain times of the year, many very small gnats (1 mm or less) appear to come from house drainage system. I have been told they enter through the vent pipes and that they can be screened out at the vent pipes. They are so small that the screen would need to be fairly fine grained.
