Need input for bats in venting

Looking for input on bats roosting in vents under eaves
Screening is behind blocker,,,,I now I cut secure cobra or attach screen,,,but looking for other options

Thanks

Vinke,

I like kwik mesh, color match painted, still screen so maybe not what you are looking for, but I get a fair amount of these venting gaps
and the material works well, comes in multiple widths and is fairly simple to bend and attach with brads...

Not sure if that was what you are looking for.....
