Anyone have any ideas on a better solution to fill these brick vents? I currently have some plastic mesh stuffed in there, but I was just under the house rebaiting and there were a lot of bodies in one area down there, which was on the other side of these vents. The rest of the vents on the house were easier to seal up. I'm suspecting that they are making it past the mesh. Ideally I'm looking for a solution that still allows some airflow...if there isn't one, I will have to just stuff steel wool on all of them. On a side note, the moles have made several forays under the foundation and I've heard that rats (and mice) can use these tunnels to get under the house. Is there anything that can be done for that? The moles like to tunnel right along the block skirting and apparently have gotten down low enough to circumvent the foundation.
