This article series explains the purpose of drainage openings & rain screens in solid brick walls and in some brick veneer walls: brick wall weep holes and recommends their use in new construction and in some brick wall repairs or retrofits.

Retrofit Brick Veneer Wall Weep Opening Covers & Screens

Rid O Mice veneer wall drain screen retrofit product - ridofmice.net

Rid-O-Mice, a producer of several types of brick veneer wall drain opening screens and covers (at left), advertises their product as preventing invasion of the wall by mice, scorpions, insects and other pests.

There's not much to attract a mouse to the cavity in a brick veneer wall, but as we illustrated in the article above, there can be a problem with clogging of these drain openings by mud daubers, wasps, other insects, and perhaps other small critters.

Adding an appropriate screen will keep these creatures out of the wall drain opening. [Image used with permission of Rid-O-Mice.]

The company provides no direct contact information but provides a contact message page at their website: http://ridofmice.net

This and other veneer wall vent product sources are given near the end of this article.

Watch out: adding a veneer wall vent or drain screen should reduce the chances of clogging from insects or animals, but if the wall was improperly constructed so that the opening does not actually vent the wall (for example if the opening is blocked inside the wall by fallen mortar or if the flashing in the wall was not properly placed) the vent screen cannot correct those defects.

Reply:

Several manufacturers provide brick wall weep hole systems that assure that moisture or water behind the brick wall or brick veneer can drain out of the wall while at the same time insects or larger critters are kept from entering the walls.
