Maybe where David camps that kind of screening works, keeping out the
Chihuahuas and Pekinese, but out here on the west coast of Canada(and
I am sure other parts of the world) you can be, a certain times of
the years, plagued by no-see-ums that easily easily get through that
kind of screening and the stock screening found in the camper poptop,
rear hatch screen, and window screens.

I replaced all my screening with a finer mesh no-see-um proof
material (sourced locally). Its a very fine weave, and has a strand
that runs diagonally across the tiny square formed in a regular warp-
woof weave.

It is a really fine weave, trade off is that air flow is reduced
compared to the stock stuff. But crimny, if you have ever been
exposed to the clouds (no hyperbole) of no-see-ums that come out at
dusk, especially near a river on the west coast, then you accept that
trade off.

yes, the teeny tiny buggers bite. how they manage to give you such a
hit, a very palpable hit :) with mouth  parts that must be measured
in microns, is beyond me.

The netting material we used on that, btw, was/is ordinary
Fiberglas-core window screening.  Much sturdier than regular 'skeeter
net and rolls up very nicely around the batten that stretches the
vertical part down to the lip of the companionway.
