If you live in the Northeast, you’re no stranger to a mouse in your house. However, a rodent gnawing its way through the electrical wiring in your home is much more likely than you think. Let’s cover why rodents chew wires and the steps you can take to prevent these furry invaders from doing damage to your home.
Rodents don’t care what stands between them and the warmth of your home. They have been known to crawl in through holes as small as half an inch and chew through drywall, wood, and often wires. “Mice are known to gnaw through walls, wood, and wires,” says Jim Fredericks, technical services director for NPMA. “The damage to wiring within walls can cause house fires.”
Why are they always chewing? Their teeth are always growing! Similar to a cat’s claws, rodents will chew on just about anything to optimize their teeth for long-term eating and chewing. Since mice and rats don’t have any means to keep their teeth well-manicured, they typically will find something hard and reliable to file down their rapidly growing teeth. In this case, wires made of metal and copper make for a good texture to sharpen their teeth.
