What method is NOT part of subterranean termite control techniques?

The method that is not part of subterranean termite control techniques is ignoring cellulose debris. Subterranean termites are attracted to cellulose, which is found in wood, paper, and other plant-based materials. Ignoring cellulose debris in and around structures can create an environment conducive to termite infestation. Effective termite management involves removing or properly managing any cellulose material that may attract termites.

In contrast, proper construction practices help to reduce the risk of termite access and damage by eliminating vulnerabilities in a building's structure. Chemical control is often used to treat soil and wood to provide a barrier against termites. Regular cleaning is also important as it helps to eliminate potential food sources and reduce the likelihood of attracting termites. Therefore, ignoring cellulose debris stands out as a method that does not contribute to effective subterranean termite control.
