What screen mesh stops no-see-ums and gnats?
The 20 by 30 no-see-um mesh — a weave tight enough for biting midges that standard screening lets through.
What screen mesh stops no-see-ums and gnats?
You want the 20 by 30 mesh — the count refers to openings per inch, and at that density the weave stops biting midges, gnats, and other insects small enough to walk straight through standard screening. V-Track insect screens come in both the standard 18 by 16 mesh, which handles mosquitoes and flies and maximizes airflow, and the 20 by 30 no-see-um weave for properties near water, woods, or anywhere the tiny biters rule the evening.
Both ride the same keder-bead retention system — the fabric edge is welded to a continuous bead captured in the track for the screen's full height, so there are no edge gaps for pests to push through. If your patio backs to a creek or pond anywhere in our Virginia, Maryland, or DC service area, spend the little extra on the tighter mesh; it is the difference between a screened porch and a genuinely bug-free one.
