Thank you.

Weep holes can be found on most any brick home and quite commonly on other types of structures too. For obvious reasons, any "hole" that leads to an interior wall void of a structure tends to increase the potential for a pest problem to develop. In my estimation, weep holes account for a lot more problems than realized. In fact, I've seen termites, wasps, roaches, crickets, earwigs, millipedes, ants and many other invasive pests take advantage of this "open door" to what amounts to a great nest site: wall voids where it's nice and warm, shady, moist and protected! Yet it's not likely we'll see less utilization of weep hole design in residential homes anytime soon and though there has been some attempts at making them insect proof, for the most part they still represent one of the most likely places for invasive pests to enter a structure. More importantly, the "purpose" of any weep hole is really at fault. Think about it: weep holes are designed to release water. And what is it that most invasive pests seek? Moisture (water). Safe harborage. Darkness aka shade. Basically everything a weep hole can provide!
