Mice, rats, squirrels, and more can easily penetrate a location, crawling through small spaces and being undetectable when their numbers are small.

This includes your car where they can live in the hood, trunk or even the interior of the vehicle.

Once they infest a place it can be difficult to remove them.

They often inhabit cars during colder months, seeking shelter and warmth or target vehicles that are not used frequently as they will not be detected right away.

It can be hard to remove these rodents once they claim location, so using the best rodent repellent for cars will work to drive them away, protect your car, and prevent future infestations in a way other rodent removal methods cannot.

Damage to your car and health

Both the damage to your car and the disease brought on by rodents infesting an area can prove dangerous.

Mice, rats, and other rodents can easily carry diseases and make your car unsanitary.

This is a common problem caused by rodent infestations no matter its location and requires cleaning after the rodents have been removed from the area.

But diseases are not the only problem. Rodents can build nests, store food, and gnaw through the wires of your car too.

Once under the hood, they can do extreme damage to a car requiring minor remains or preventing the car for operating properly and safely.

This is the main issue with rodents in or near your car. They work quickly and once they are in a place, they can start to cause problems.

Repairs to your car’s wires, engine, and more can be expensive and prove to be difficult to replace in cases where the car is an older model.

Why not to use traps and poison

While traps and poisons can be quick and efficient methods to remove rodents from the home, using repellents is safer, cleaner, and a better solution for protecting your car.

Traps and poisons offer a lot of features that will not benefit infestations within a vehicle.

They can often be messy and require clean up and disposal of bodies. They are not safe for pets and children to be around either which can be a disadvantage.

Traps need to be replaced frequently and poisons use unsafe chemicals in order to kill the pests.

These two options also do not prevent future infestations from occurring, acting as only after the fact solutions to an infestation.

Benefits of using repellents

Repeller features are different than those of traps and poisons. This makes them safer to use and can prove to be less work.

There are three main types of repellers that can be used in cars: sprays, ultrasonic devices, and scent-based repellents.

These repellents attack the sense of rodents without harming the creatures, either their smell or hearing.

The main benefit of these types is that they are non-toxic, do not feature chemicals, and do not harm the rodents they are repelling.

As they are often made naturally with safe solutions, they are safe to use around children and even pets.

These methods act as a humane way to remove and discourage rodents from the premise and limit their future activity. There will be no need to dispose of rodents as the method does not kill them.

These solutions also last longer than traps and poisons, not needing to be replaced or reapplied as frequently.

The range of these products allows them to protect larger areas too. This can be beneficial to keeping rodents out of your car as you can protect infestations from occurring in the home, garage, and other areas.

With these areas protected, there is less rodent activity nearby, limiting the number of rodents trying to access the car.

Unlike poisons and traps, they are safe to use in vehicles and will not cause messes to occur.

These are the key features to look for in your repellent as they will be the more efficient and safe repellent to use to rid rodents from your car.

Spray repellents

Spray repellents act on the sense of smell. These solutions are made almost completely with essential oils. This allows the solutions to smell nice and not leave behind a bad odor.

This smell based on essential oils is pleasant to humans, it is repulsive to rodents.

While other essential oils like rosemary oil and cinnamon oil are also used, the most popular of the oils is peppermint. It produces a minty fresh scent and works hard to drive away the pests.

When using spray repellents for mice and other pests, you can apply to nearly all surface areas, both inside and outside the car.

This allows you to further protect your car as you limit the number of rodents within the entire area.

Most sprays will require a respray within a month or less to fight against future rodent issues.

These are safe to use in homes and many are designed to not stain fabrics and surfaces.

When selecting a spray, the key trait to look for is how large of a container you wish to purchase.

Larger containers work great for those who experience infestations frequently and those wanting to cover more area beyond their vehicle.

Those wishing to treat a single case of rodents or to have some on hand can purchase smaller bottles.

Under hood ultrasonic repellents

These devices work by being placed under the hood of a car or another vehicle. They are powered by being connected to the car’s own battery.

When the car is parked and turned off, the device will turn on and emit a sound wave. The frequency of this wave is undetectable to humans.

However, rodents like mice and rats will be disorientated and irritated by the sound, forcing them to vacate the area protected by the ultrasonic speaker’s range.

These devices are intended to protect a car, though if you have access to a 12 to 24 volt battery, you can place them in other regions.

So long as the device is connected to a power source it will work to drive away current and future rodents.

Two important features to look for within these devices are their ability to automatically turn on and off. This helps you conserve energy and protect your car battery.

One automatic switch can be triggered whenever the car is used, as the device will not need to be operating during a time when rodents cannot access the vehicle.

Secondly, the device should automatically switch off whenever your car battery is low, falling below 10.5 volts.

Scent repellents

Scent repellents are often featured in bags or pouches that feature a substance coated in essential oils.

There can be a couple of essential oils used to target the senses of rodents, but the most popular choice is peppermint oil. It is the strongest scent, greatly hated by rodents, and is pleasant to smell.

These bags, often sold in packs of various quantities, last for around a month before their scent is diffused too much. Then they must be replaced with a new bag.

They are easy to hang from a variety of places, such as in your car or your car’s trunk, and work to repel rodents without harming the creatures.

They also produce pleasant scents that are not harmful to either the creature of people.

There are a number of repellents that might work well for use against rodents invading your car.

It’s important, though, to always consult an industry professional before you use any particularly pest control product or intervention method.
