Rats get into a car—what should you do? - in detail

Rodents can enter a vehicle through open doors, gaps in the firewall, or ventilation openings. Their presence often leads to gnawed wires, contaminated upholstery, and unpleasant odors.

Immediate steps

  • Disconnect the battery to prevent short circuits.
  • Inspect the engine compartment for chewed hoses, exposed wires, and droppings.
  • Remove visible debris with gloves and a disposable cloth.
  • Ventilate the interior by opening windows and doors for at least 15 minutes.

Cleaning and repair

  • Use a vacuum with a HEPA filter to extract nests, droppings, and hair from seats, carpets, and trunk.
  • Apply an enzymatic cleaner to all surfaces that may have been soiled; allow adequate dwell time before wiping dry.
  • Replace any damaged wiring harnesses, coolant hoses, or brake lines identified during inspection.
  • Check the vehicle’s fuse box and relays for signs of gnawing; replace compromised components.

Preventive measures

  • Seal entry points: install steel wool or copper mesh in gaps around the firewall, under the hood, and in the trunk latch area.
  • Keep the garage door closed and maintain a clean storage environment; eliminate food sources that attract rodents.
  • Deploy ultrasonic repellers or scented deterrents (e.g., peppermint oil) in the parking area.
  • Schedule quarterly inspections, focusing on the undercarriage and engine bay, especially during autumn and winter when rodents seek shelter.

When to seek professional assistance

  • Extensive wiring damage that affects multiple systems.
  • Persistent odor after thorough cleaning.
  • Evidence of infestation in hard-to-reach areas such as the transmission tunnel.
  • Lack of tools or experience to safely disconnect electrical components.

Following these actions restores vehicle functionality, reduces the risk of future infestations, and safeguards the safety of occupants.
