When treating slabs containing or covering heating ducts, you should reconsider treating if the ducts?

When treating slabs that contain or cover heating ducts, the presence of ducts made of a material containing cellulose is a significant concern. Cellulose is an organic material that is highly appealing to termites as a food source. If the ducts are made of cellulose-based materials, they could potentially attract termites, making it important to reconsider the treatment strategy to ensure that the treatment is effective and that it does not inadvertently promote termite activity.

In scenarios with insulated ducts, exposed ducts, or ducts connected to a furnace, while these factors may influence your treatment plan, they do not present the same direct risk of attracting termites as cellulose does. Insulation might complicate treatment access, exposed ducts may offer accessible points for treatment application, and connections to a furnace might present a need for careful handling to avoid damage to the heating system. However, none of these scenarios imply an immediate nutritional source for termites as cellulose does. Thus, focus on cellulose-containing materials is crucial when assessing the risk of termite infestation during treatment planning.
