We just bought our first home and we had advice some friends that we should cover the weep holes with wire mesh, to prevent bugs and other things from going inside. Is that a good idea? Please advise.
Sorry thought this was for windows... Brick weep holes are different. Wire mesh will keep out rodents and small animals. Won't keep out bugs - your drywall does that. I would try steel wool.
