What action is vital in managing pest issues effectively?

Regular inspections and cleanliness are crucial in effectively managing pest issues because they help identify potential problems before they escalate. Maintaining a clean environment minimizes food sources and nesting areas for pests, which can deter infestations. By routinely inspecting the premises, any signs of pest activity can be spotted early, allowing for prompt and targeted interventions. Cleanliness practices, such as proper waste disposal, cleaning kitchen areas, and addressing leaks or moisture, further reduce the likelihood of attracting pests.

In contrast, increasing food sources would actually attract pests, while providing open access to buildings would create opportunities for pests to enter. Relying on natural predators may help in some scenarios but is not a standalone solution and does not address the broader issue of pest management on its own.
