Spider Shop vents for small roaches?

[WarrenB]

Hello all. I'm fixing to set up a small Oxyhaloa duesta colony with a bit of a focus on security. I'm using a gasket-sealing tub and for ventilation, some of the screw-on vents from the Spider Shop, this side of the ocean. They're supposed to be able to keep phorid flies out of tubs, but would they keep duesta newborns in? I have the vents here: the biggest holes are about 1mm x 1/2mm. (1/32" x a bit over 1/64")

I have a bit of micromesh on the way too, if they need a little reinforcement.
