10 Alarming Signs Rodents Are Invading Your Home (And What to Do)

3. Gnaw Marks and Damage

Rodents have ever-growing incisors that require constant gnawing to keep them in check. This behaviour leads to one of the most destructive signs of their presence: gnaw marks. These marks can be found on various materials, including wood, plastic, and electrical wiring. The damage caused by rodents can be extensive, leading to structural weaknesses and posing fire hazards due to chewed wires. Identifying gnaw marks is crucial for assessing the extent of an infestation. Fresh gnaw marks are lighter in colour and will darken over time, providing a timeline of activity. This information can help determine the severity of the problem and guide the implementation of control measures. Addressing structural damage promptly is essential to prevent further deterioration and maintain the integrity of your space. In addition to repairs, sealing entry points and using rodent-proof materials can help deter future infestations.
