A rodent infestation often starts with an opportunistic rodent finding entry into a building through gaps under doors, damaged drainage systems, or surprisingly small holes. These openings provide easy access to shelter, warmth, and potentially a sustainable food source. Ensuring these entry points are sealed and reinforced with appropriate materials is crucial in minimizing the risk of rodent infestation.

As regulations on rodenticide usage become stricter, proofing becomes even more essential. For instance, toxic baiting is now subject to specific criteria, including the completion of proofing works. This underscores the significance of effective proofing measures in pest control efforts.
