What should you do if rats crawl under the hood? - in detail
If small mammals are found beneath the engine cover, first secure the vehicle. Park on a level surface, engage the parking brake, and turn off the ignition. Allow the engine to cool completely before opening the hood to avoid burns.
Perform a visual inspection. Look for gnaw marks on wires, hoses, and the battery. Identify any nests, droppings, or chewed components. Use a flashlight to reach hidden areas.
Remove the intruders safely. Wear thick gloves and a mask to protect against bites and disease. Capture each animal with a humane trap or, if necessary, a sturdy container. Release captured rodents far from residential zones, complying with local wildlife regulations.
Disinfect the affected zone. Apply an approved rodent‑proof cleaner to all surfaces, paying special attention to electrical connections. Replace any damaged wiring, hoses, or sensors with new parts that meet manufacturer specifications.
Implement preventative measures. Seal entry points such as gaps around the firewall, intake ducts, and cable bundles with metal mesh or silicone sealant. Install a rodent‑deterrent device—ultrasonic emitters or peppermint oil sachets—inside the engine compartment. Schedule regular checks, especially before seasonal temperature changes, to catch early signs of activity.
Document the incident. Record the date, location of damage, and parts replaced. Keep this log for future reference and for warranty or insurance claims if needed.
