Leaving Your Car for the Holidays? Do These 6 Things First

By EchoRepel Team·12 September 2026·4 min read

Every festive season, millions of cars sit parked for days while their owners travel home. And in the weeks that follow, workshops fill up with chewed wiring and dead batteries. A car standing still is far more vulnerable than one being driven — so before you lock up and leave, run through this quick checklist.

1. Park clean and smart

Clear food, wrappers and leaves from the cabin and engine bay, and park on dry, higher ground away from garbage, drains and bushes.

2. Set up a rat deterrent

This is the step almost everyone forgets. A quiet, warm engine bay left for days is exactly what a rat is looking for. A deterrent running in the bay stops it becoming a nest while you are gone.

3. Inflate the tyres

Correct pressure reduces the flat spots that can form when a car rests on the same patch of rubber for a week.

4. Leave fuel in the tank

A reasonably full tank leaves less room for condensation to form inside.

5. Tend the battery for longer trips

A week is usually fine, but for anything longer, disconnect the battery or use a trickle charger so you are not greeted by a dead car.

6. Do a quick walk-around when you return

Before starting up, glance under the bonnet for droppings or nesting material, so a small visitor does not become a big surprise on the road.

For the deterrent in step 2, the EchoRepel Car Rat Repellent runs on its own while the car is parked — so you come back from the break to a car that starts, not a repair bill. See also what happens to your car when it sits parked for a week.

Frequently asked questions

What should I do before leaving my car for a week?

Park it clean and on dry, higher ground away from food and bushes, inflate the tyres, leave some fuel in the tank, disconnect or tend the battery for longer trips, and set up a rat deterrent in the engine bay.

Why do rats target cars during the festive break?

Because so many cars sit unused for days at once, giving rats undisturbed time to nest and chew, and the season often coincides with cooler, wetter weather that drives them to seek shelter.

Will my battery survive a week parked?

A healthy battery usually will, but an older one may not — for longer trips, consider disconnecting it or using a trickle charger.
