What is the maximum distance between holes when drilling through a slab floor adjacent to the perimeter foundation?

36 inches
24 inches
12 inches
18 inches

The correct answer is: 12 inches

When drilling through a slab floor adjacent to the perimeter foundation for pest control treatment or inspections, the maximum distance between holes is typically 12 inches. This close spacing is necessary to ensure effective application of treatment and to facilitate the best possible coverage for eliminating wood-destroying organisms, such as termites. The objective is to create a thorough barrier or an effective access point for the treatment material to penetrate the area where infestation risks are highest, which directly contributes to better pest management. This method enhances the likelihood of successfully reaching the pests by ensuring that the treatment can be effectively distributed in the targeted areas without leaving gaps that could allow for pest survival.
