The correct answer is: Long

The process of drilling horizontally through the exterior foundation just below the slab level is commonly referred to as "Long" drilling. This technique involves creating a passage through the foundation to allow for various purposes, such as pest control measures, plumbing, or electrical installation. In pest control specifically, this method is effective for applying treatments in areas that are otherwise difficult to access. By drilling horizontally, the procedure minimizes disruption to the structural integrity of the foundation, while also ensuring that any necessary treatments can be applied evenly and thoroughly within the desired area. Understanding the terminology and the methods used in foundation modifications is crucial for professionals in home inspections, especially regarding pest management and structural integrity assessments.
