Yes, and it's one of the more serious risks of leaving squirrels in a roof space unaddressed. Squirrels are rodents, and like other rodents their front teeth grow continuously throughout their life, which drives an instinctive need to gnaw on hard materials to keep them worn down. Cable insulation is an easy, convenient target when it's running right through their nesting area.
Why loft wiring is particularly at risk
Most homes route a mix of electrical cabling, aerial and satellite leads, and sometimes alarm or network cabling through the loft space. Squirrels nesting nearby will often gnaw at whatever is within reach, exposing bare wire underneath the chewed insulation. This can happen gradually over weeks without any visible sign from inside the living space below.
The risks this creates
- Exposed wiring increases the risk of electrical fire, particularly where cables run close to dry insulation or timber
- Damaged cabling can cause intermittent faults that are hard to trace
- Repairs to chewed wiring often mean an electrician needs loft access, adding cost on top of squirrel removal
- Some home insurance policies expect pest damage to be dealt with promptly, and unresolved damage can complicate a claim
Signs the wiring may already be affected
Flickering lights, circuits tripping without an obvious cause, or a burning smell near the loft hatch are all signs worth taking seriously if you know or suspect squirrels have been present. If you notice any of these alongside other signs of squirrel activity in your Theale property, it's worth having both the pest issue and the wiring checked without delay.
Why this makes prompt action important
The longer squirrels are left undisturbed in a loft, the more opportunity there is for wiring damage to build up. This is one of the main reasons we recommend dealing with a suspected infestation as soon as the early signs appear, rather than waiting to see whether the noise settles down on its own.
