Before leaving your car for Diwali, remove food and nesting material, choose a clean parking space and make a battery plan suited to your vehicle. Arrange a bonnet inspection before the first drive back, especially if the car has stood beside drains, bins or stored clutter.
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
Battery condition and vehicle instructions determine the storage plan. Ask about an appropriate maintenance charger or the permitted shutdown procedure rather than automatically disconnecting power after a set number of days.
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.

| Rat deterrent set up in the engine bay | ☐ |
| Tyres at the correct pressure | ☐ |
| Fuel tank at least half full | ☐ |
| Battery plan for trips longer than a week | ☐ |
| Valuables, documents and toll account details out of sight or taken with you | ☐ |
| Windows fully closed; car locked | ☐ |
Away for more than two weeks?
- Ask someone to start the car and drive it for 15–20 minutes once a week. Short idling in the parking spot isn't enough to recharge the battery.
- Or disconnect the negative battery terminal. Note that this may reset the clock, radio presets and some settings; check your owner's manual first, especially for newer cars.
Why society basements are risky over the holidays
During the festive break, whole basements go quiet. Dozens of cars sit unused at once, building staff may be on leave, and garbage collection can slow down. For rats, that's an ideal week: warm engines that don't move, no people around, and food nearby. See rats in society basement parking for what societies can do.
When you get back: first-start checks
- Walk around the car, tyres, any leaks under it.
- Open the bonnet: look for droppings, nesting material and chewed wires or hoses.
- Check the cabin for a musky smell or chewed items.
- Start the car and watch for warning lights.
- If a warning light appears that wasn't there before, don't drive far, have it checked. A bitten sensor wire is a common cause.
For leaving your car for diwali, the EchoRepel Car Rat Repellent is a supporting option using ultrasonic sound that rats and mice want to avoid. It is poison-free. For leaving your car for diwali, use the device only as instructed and assess new signs rather than assuming protection.
Give the person checking your car a clear job
If someone will look after the car, ask for a visual check rather than simply starting it. They should look around the tyres and accessible engine-bay areas for fresh debris, leaks or chewing. Leave the workshop and roadside-assistance details where they can find them, and agree when they should contact you instead of driving.
Only an authorised, insured driver should move it. A short idle in a basement is not a useful substitute for a charging plan and exposes people to exhaust. If driving is appropriate, it should follow the vehicle instructions and happen outdoors after the car has been checked.
Choose battery care using the handbook
Do not disconnect a battery just because a holiday crosses an arbitrary number of days. Vehicle security, battery condition, connected accessories and manufacturer requirements differ. Some cars need a specific shutdown procedure, and disconnecting power may affect alarms or stored settings.
Ask a workshop whether a compatible maintenance charger is suitable and whether your parking area has a safe, permitted supply. Keep any charger and leads protected as their manuals require. For an EV, follow the manufacturer's storage advice for both the traction battery and auxiliary system rather than applying a petrol-car routine.
Use the return inspection to decide what happens next
Before starting, compare the bonnet area with a photograph taken before departure. Fresh shredded material or droppings warrants a check for animals and damage, not just a quick wipe. Visible bare wiring, damaged hoses, warning messages or a fuel smell needs professional advice before use.
If everything looks normal, check tyres and lights and begin with an unhurried local drive. Do not leave the first inspection until the family and luggage are loaded for a long journey. A deterrent can be a supporting measure during storage, but it cannot establish that the car is safe to drive when you return.

Frequently asked questions
Should I disconnect the battery for every holiday?
No. Follow the vehicle’s storage instructions and assess battery condition and accessories. Disconnection can affect security or settings, and some vehicles require a specific procedure.
Can my neighbour just idle the car in the basement?
Do not run the engine in an enclosed basement. Brief idling also does not replace an appropriate battery plan. Agree on safe visual checks and any authorised driving beforehand.
What should stop the first drive after I return?
Suspected cable or hose damage, leaks, a fuel smell or new warnings need professional advice. Do not load up for a long trip before checking the car.
Should I leave the keys with a neighbour?
Only if there is a clear need and someone suitable is authorised to use the car. Agree on visual checks, security and when to call you or a workshop before handing over keys.
