Squirrel Damage in Schools: A Hidden Fire Risk

Recently, we attended a school in North Yorkshire where significant damage had been caused by squirrels inside the building. The squirrels had taken a particular liking to the fire alarm system cables, chewing through the insulation and causing the system to short — repeatedly triggering the alarms.

While this may sound unusual, damage like this is far more common than many people realise and can pose serious safety risks.

Why Do Squirrels Chew Electrical Cables?

Squirrels and rodents constantly gnaw on hard materials because of their teeth. Their front teeth, known as incisors, never stop growing throughout their lives. To keep them worn down and sharp, they must continually chew.

Unfortunately, electrical wiring and plastic cable insulation are often targeted because they are easy to access in lofts, ceiling voids, and wall cavities.

Common targets include:

Fire alarm wiring
Electrical cables
Internet and communication lines
Lighting circuits

The Serious Risks of Rodent Gnawing

Chewed wiring is more than just an inconvenience — it can create genuine safety hazards.

Rodent and squirrel activity can lead to:

Fire alarm failures or false activations
Electrical shorts and power loss
Increased risk of electrical fires
Expensive repair and downtime for schools or businesses

In environments such as schools, where safety systems are critical, early intervention is essential.
