When should you drill and treat brick or stone veneer?

Drilling and treating brick or stone veneer is particularly important when the brick ledge is below grade. This is because areas that are below grade are often more vulnerable to moisture accumulation and water intrusion, which can create an ideal environment for wood-destroying pests such as termites. When the ledge is positioned below ground level, it increases the risk of pests accessing the wooden structures in the home, since they can enter more easily at ground level where soil and moisture are present.

By drilling and treating these areas, pest control professionals can effectively apply treatments that help to prevent infestations from reaching the wood components of the structure. Addressing potential entry points in below-grade areas is essential for preserving the integrity of the building and preventing costly damage from wood-destroying insects.
