According to the Kentucky Department of Agriculture standards, which type of debris must be removed from beneath structures?

The correct answer is cellulose because cellulose is an organic material that comes primarily from plant sources, such as wood and paper products. When debris containing cellulose is left beneath structures, it poses a significant risk for attracting termites and other wood-destroying insects, which thrive on such materials. The presence of cellulose debris creates an ideal environment for pest infestation, leading to structural damages and potential costly repairs.

In contrast, while plastic, metal, and glass may also need to be managed for various reasons such as safety and aesthetics, they do not present the same level of risk for pest-related issues as cellulose debris does. Therefore, the specific emphasis on removing cellulose debris aligns with pest control practices aimed at preventing infestations and maintaining structural integrity.
