While this is a perfectly fine screen cover for reptiles and one that could even work to keep Madagascar Hissing Cockroaches in, I wouldn't trust it to be able to keep small cockroaches in our out. It just isn't designed for that... Putting a layer of Vaseline can be an effective barrier for cockroaches as they can't climb across it.
