Check the cabin before using the fan. Droppings and chewed paper need attention.
Inspect storage spaces and footwells. Avoid disturbing dry droppings or nesting material.
Use the vehicle manual. A contaminated filter needs replacement after safe removal.
Follow CDC vehicle guidance: ventilate first, wear gloves and disinfect. Never vacuum dry droppings.
Use protected placements away from children and pets. Keep traps outside the cabin.
Secure birdseed and pet food. Clear garage clutter and check door seals.
Remove cabin snacks. Ask a workshop about persistent smells and damaged intake barriers.
