What is the function of flashing in pest management?

Flashing serves an essential role in pest management by preventing leaks around structures. It is a material, often metal or plastic, that is installed in areas where water might infiltrate, such as roof edges, around chimneys, and in the junctions between different building materials. By creating a barrier against moisture, flashing helps to maintain the structural integrity of a building and diminishes the likelihood of water accumulation that can create ideal conditions for pests, such as termites and carpenter ants. Properly installed flashing can significantly reduce the chances of pest infestations by ensuring that moisture is diverted away from vulnerable areas, ultimately contributing to a healthier and more pest-resistant environment.

The other options are not the primary functions of flashing. While it may indirectly influence pest activity, its main role is to stop water intrusion rather than directly attract, trap, or insulate against pests.
