Of all the damage squirrels can cause in a roof space, electrical damage is the one with the most serious consequences. It's easy to think of squirrels as a nuisance rather than a genuine safety risk, but gnawed wiring in a loft is a well-documented cause of house fires, and Woodley lofts are no exception.
Why Squirrels Gnaw Electrical Wiring
A squirrel's front teeth grow continuously throughout its life, so gnawing is instinctive behaviour rather than a targeted attack on your wiring specifically. Cable insulation happens to be an easy, convenient material to chew, and wiring often runs directly through the areas squirrels favour for nesting, which puts the two in close and repeated contact.
The Real Risks This Creates
- Exposed live wiring in the roof space, creating a fire risk from arcing or short circuits
- Damaged wiring to smoke alarms, which can leave a property without a working early-warning system
- Chewed satellite, aerial or telecoms cabling running through the loft
- Damage near loft-based electrics such as immersion heater controls or alarm systems
Warning Signs to Watch For
- Lights flickering without an obvious cause
- Fuses or the RCD tripping repeatedly, particularly on circuits that run through the loft
- A burning or unusual smell coming from the loft or upper floor
- Visible chewed or exposed cable if you can safely see into the roof space
What to Do If You Suspect Electrical Damage
If you notice any of these warning signs alongside evidence of squirrel activity, treat it seriously. Avoid entering the loft yourself if you suspect exposed live wiring, and consider isolating the affected circuit at the consumer unit if you can do so safely. This is a situation where a qualified electrician and a pest control professional often need to work together – the electrician to make the wiring safe, and pest control to remove the squirrels and close off how they got in.
