Perforated plastic sheet - any ideas ?

[Blockplane]

I am sure that I have seen rigid plastic sheet, with approx 1/2" holes on sale somewhere, but my mind is a complete blank as to where.

I need to come up with about a dozen pieces, roughly 10" X 15", ideally in black, to use as eves fill to keep the jackdaws from nesting.

Any ideas?

a bit like grass board/mesh?

You could do with something with holes less than 6mm to exclude bees and wasps.

This any good? Not that being on clearance attracted me to it
