There are almost infinity sizes of screens and screen
openings that can take care of this job. They make metal and wire mesh so fine, with openings so small these days, you can't even see through the material. For your purposes - try a stainless steel
wire mesh - maybe about a 250 x 250 Custom Wire Cloth - Belleville Wire Cloth Co - Cedar Grove, NJ
This material will be rust proof, and should let enough ventilation to come in and out - without letting in any bugs or mosquitoes.
Good Luck. adios
