Rodents pose an expensive threat to trucks and vans

According to Aviva, there has been a 28% increase in claims involving rodent damage, with a noticeable spike during the colder months of December and January.

The cost of claims also increased, with the average claim in 2024 rising to £2,494 - an 11% increase compared to £2,253 in the previous year. In one case, rampaging rodents caused over £24,000 of damage, leading to the vehicle being written off.

Types of damage commonly cited by customers include rodent nests discovered within engine compartments and behind passenger airbags and numerous cases of chewed wiring and cabling, leading to damage across dashboard sensors, batteries, suspension systems and gear mechanisms.

Seats, seatbelts, footwells and carpets have also been gnawed, while there has been fuel and water leaks caused by rodents biting into fuel tanks and piping systems

James Driscoll, motor claims manager at Aviva, said: “Many people are aware of the damage that rodents can cause to properties, but may not realise they also like to explore our vehicles. In the winter months, mice and rats look for warmer places to nest and they can squeeze into the tiniest of gaps, including the grilles, vents or open windows of vehicles.

“Once inside, rodents can cause significant damage, from chewing wires and gnawing at interiors, to nesting in engines. The issue tends to be more prevalent in larger cities, where higher population density, extensive drainage networks and ageing infrastructure create ideal conditions for vermin to thrive.”

Driscoll says it is worth being extra-vigilant, especially during the winter months. “If you notice any signs of gnawing or suspect rodent damage in your car, contact your insurer straight away,” he added.
