What is the maximum distance that drill holes must be spaced apart?

The maximum distance that drill holes must be spaced apart is typically up to 12 inches. This guideline ensures that when treating for termites, the application of the product is thorough and effective in reaching potential conveyances of termite activity, including wood members or infested areas. Spacing holes too far apart could result in missed sections of wood that could harbor termites, leading to incomplete treatment and increased risk of an infestation returning. The 12-inch spacing allows for adequate distribution of the pesticide or treatment method being employed, maximizing the effectiveness of the pest control strategy. This distance aligns with standard pest control practices, ensuring comprehensive coverage while minimizing the risk of damage to the property being treated.

In contrast, options that specify distances greater than 12 inches would not provide the same level of assurance in effectively treating areas where termites may be active, potentially allowing for gaps in coverage that could undermine the treatment's success.
