Final answer:
Generally, holes drilled for 'drilling and treating' method for termites should be no more than 12 inches apart to create a continuous termiticide barrier in the soil, although the exact spacing can depend on various factors.
Step-by-step explanation:
When using the "drilling and treating" method for termites, the spacing between the holes drilled into the ground for termite treatment depends on the label instructions of the product being used, the construction type of the building, and the severity of the infestation. However, as a general guideline, holes should typically be drilled no more than 12 inches apart around the perimeter of the foundation or affected areas.
This ensures that the termiticide forms a continuous barrier in the soil to protect the structure from termite invasions. It's essential to follow the instructions provided by the manufacturer and a pest control professional for the specific situation and termite treatment product.
