You may have noticed gaps between the bricks of your home. Although these may look like large cracks, they are purposely left between bricks in the lower layers of external walls to assist in proper drainage and ventilation. These gaps are called weep holes. Without ventilation, internal wall studs and other building materials within the wall cavity can become damaged by damp conditions. For this reason, it is important that you do not block weep holes or seal them with caulk. The problem with weep holes is that they act as an entry door for pests to access the interior of your walls. To help prevent this from happening, you should have weep hole covers installed. Our Retrofit Weep Hole Covers made by Tamlyn® will keep the critters out! Custom fit weep hole covers are a low-cost solution for additional pest prevention. These covers are specifically designed to eliminate the chance for pests to enter your walls through weep holes without interfering with the necessary ventilation and drainage the weep holes provide. Whether or not you decide to install weep hole covers, you should call Armor Pest Control to perform quarterly visits to maintain a pest barrier around your home. This will give you peace of mind and ensure that any pests are treated before they become a severe problem.
