What type of damage can rodents cause to electrical infrastructure?

Rodents can cause significant damage to electrical infrastructure primarily through their tendency to gnaw on wiring and insulation. When rodents chew on electrical wires, they may damage the protective coatings, exposing the metal wiring underneath. This can lead to short circuits, which occur when the electrical current flows along an unintended path. Short circuits can generate heat and may ultimately result in electrical fires, posing a serious hazard in residential and commercial buildings.

This type of damage is particularly concerning because it compromises not only the functionality of electrical systems but also the safety of the property and its occupants. Unlike the other options, which pertain to different types of damage (such as plumbing or structural issues), the risk of fire and electrical failure is a direct consequence of rodent activity on wiring. Understanding this risk is crucial for pest management and prevention strategies involving rodent control.
