When mice sneak into homes and businesses, they don’t just nibble food or make nests. One of the most costly and dangerous behaviours they’re known for is chewing through electrical wires. This blog explores why mice chew cables, the risks involved, and how to prevent major damage before it happens.
Why Mice and Wiring Don’t Mix
Mice have an instinctive need to chew constantly due to their ever-growing teeth. Unfortunately, electrical cables are often their target because they’re easy to access behind walls, under floorboards, or in attics. Once gnawed, wires become exposed and pose serious fire hazards. According to UK fire statistics, rodents cause thousands of electrical fires each year, many of which begin invisibly in hidden spaces.
If left undetected, this kind of damage can lead to major electrical faults or even void home insurance policies in the event of a fire. Homeowners often only realise there’s a problem when the lights flicker, fuses trip, or a burning smell emerges near outlets.
Spotting early signs is crucial. You might hear faint scratching or nibbling behind walls, especially at night. In some cases, you’ll find droppings or small pieces of chewed material near skirting boards, in loft spaces, or behind kitchen appliances.
The Importance of Swift Action
Once mice are present, it's vital to act fast. Leaving a rodent infestation unchecked not only increases the risk to your wiring but also creates opportunities for further nesting and property damage. A professional pest controller can locate hidden entry points, identify nest zones, and safely remove the infestation using humane methods.
They’ll also advise whether an electrician is needed to check or repair any exposed or compromised wiring. Acting quickly helps prevent the issue escalating into a much more expensive or dangerous one.
How to Help Protect Your Home
Preventing a problem is always better than reacting to one. To reduce the risk of mice entering your home and causing damage:
- Block any small external gaps around pipes, vents or eaves
- Keep stored food sealed and avoid leaving pet food out overnight
- Regularly check attics and underfloor spaces for droppings or nests
- Maintain good cleanliness and reduce clutter around the property
Rodents can enter through a gap the size of a pencil, so even modern homes are at risk if not properly sealed.
