Of all the reasons to take squirrels in the loft seriously, electrical damage is the one with the most serious consequences. It's not a rare or exaggerated risk — squirrels are constant gnawers by biological necessity, and loft cabling is exactly the kind of accessible, chewable material they encounter as they move around a roof space.
Why Squirrels Chew Cables
A squirrel's front teeth grow continuously throughout its life, so gnawing is a routine behaviour to keep them worn down and sharp — it's not related to hunger or aggression. Cabling, being firm but not too hard, is an easy target, and squirrels will chew through PVC insulation on wiring in the same way they gnaw timber, loft insulation or old bird boxes. This applies to mains electrical cabling, telephone and internet lines, and any low-voltage wiring for alarms, aerials or smart home devices routed through the loft.
The Risks This Creates
- Exposed or damaged wiring insulation, increasing the risk of short circuits.
- A recognised fire risk where chewed cabling is left undetected, particularly in older Maidenhead properties with cabling run directly through open loft space.
- Intermittent faults with lighting, sockets, alarms or broadband that are hard to diagnose without checking the loft.
- Damage to satellite, aerial or smart home wiring that isn't always covered under standard electrical safety checks.
What to Do If You Suspect Chewed Wiring
If you notice unexplained electrical faults, flickering lights, tripped circuits with no obvious cause, or you've confirmed squirrel activity in the loft, it's worth having both the pest issue and the wiring checked. We'll flag any visible cable damage during a squirrel inspection, but a qualified electrician should assess and repair any wiring found to be compromised — this isn't something to leave until it's convenient given the fire risk involved.
Squirrel-related wiring damage is a strong reason not to delay dealing with an infestation once you suspect one. If you've had electrical faults alongside daytime noise in the loft of your Maidenhead property, contact Pest Services Berkshire for an inspection, and we'll advise if an electrician's follow-up is warranted.
