Rodent Droppings
Although the presence of rodent droppings in your home is likely to be your first concern, evidence of mice or rats is also a sign that your property is at risk of electrical problems. When rodents enter your home, they frequently chew on electrical wires and use them to grind their teeth.
If you notice any signs of an infestation, you should immediately inspect your wiring for signs of rodent damage. Consider installing devices such as sonic rodent deterrents around your wiring to keep these creatures out. If you have rodents in your home, you should consult with a pest control professional who can help you address the issue and prevent future infestations.
