 What Attracts Rats to Your Car?

Before we look at the techniques to keep the rats away, we must learn what attracts them to your vehicle. With the correct information, it is easy for you to keep them away. One reason that may attract rats is food or leftovers in the car. Rats, just like cats, have a strong sense of smell.

They smell the scents of food from a distance. As they eat the food in the car, they get their way to the cabin and car engine and eventually cause damage. So, how do you keep squirrels and rats out of your car engine? One way to answer this question is to avoid leaving anything edible in the car.   

Rats love warm and dark places to hide, breed, and store their food. Wheel arches, underbodies, and car engine bodies have lots of nooks and crannies, offering an ideal environment for the rats to hide and nest. The car engine attracts rats due to the warmth inside. They find it a cozy spot for staying and breeding, especially in the winter.

How Do You Know If a Rat Is in Your Car?

When your car stays idle for some time, it offers a cozy shelter for rodents and other animals. Rats seem small, but they create big problems in your car. They love to nest in the engine since it is dark and warm. As they shelter there, they eat the engine wires and other components as they try to trim their ever-growing teeth.

By the time you know of it, the damage is already done. We, therefore, need to protect the car engine from rats at all costs. However, sometimes we may try too much to keep them away, but they find their way into the vehicle. If you suspect a mouse or rat is in your car, the first action is to get it out. So, how do you know there is a rat in your car?

1. Bad Smells

One sign that there is a rat inside the car cabin is strange odors. Rats mainly use the venting system to access the engine’s interior components. Over time you notice odd odors coming out from air vents which is a sign of rat infestation.

2. Rat Droppings

Animal droppings are a good indicator that they have infested your vehicle. If you see some rat waste on the dashboard, seats, carpet, or around your vehicle, they are likely sheltering in your car.

3. Rat Nests

Rats love nesting in dark and warm places. Finding a nest in your vehicle is a confirmation of rat infestation. The first place to search is in the air box since that is where the engine air filter is positioned. Also, check under your vehicle’s plastic engine cover and beneath the seats. Odd sounds after turning the heater or fan indicate rodents’ nests.

4. Upholstery Damage

If you find missing insulation, chewed-up foam, or holes in your vehicle seats is a sign that rats have made a living in your car. The rats gnaw on the upholstery parts as they try to sharpen or trim their ever-growing teeth.  

5. Car Problems

Unfortunately, some drivers discover a rat infestation in their car when it fails to start or stops working as usual. The leading cause of these problems is rats chewing the wires in the vehicle’s engine compartment.

How to Protect Car from Rats

Mice, rats, and other rodents cause a big problem for your car, especially if you leave it unused for a long time. You can do a number of things to minimize the chances of rats getting in your vehicle. Here are some of the most efficient and effective ways to prevent rats from getting in your car:

Keep Your Area Clear

Rats love to shelter in warm and dark places. Parking in a clean and well-organized garage is one step to ensuring that rats do not get near your car. Ensure you park the vehicle in a well-ventilated place with low humidity. Keeping condensation and moisture on the list will help since rats thrive in moist areas.

Discard any Food Remains

Just like other creatures’ rats need food for them to survive. Therefore, leaving any type of food in or around the vehicle entices rats, mice, and other rodents to your car. Therefore, avoiding loitering food around is one of the best ways to prevent them from getting near the vehicle.

Use of Repellant Odors and Fragrances

Just like other rodents, rats do not love certain strong smells. Therefore, these odors are some of the best ways to keep rats away from your vehicle. One odor-repellant you can use is Irish spring soap. Cut the soap into cubes and tie them around the vehicle hood where it does not get hot. You can also rub the soap around different car surfaces.

The other order that rats hate is peppermint oil. Apply the peppermint oil on cotton wool and place the balls appropriately around your car. The oil has a strong scent repugnant to rats but pleasant to humans. Some recommend spraying pine sol on the engine compartment as a rat repellant. If you choose to use the pine-sol, ensure it does not get to certain car parts like the battery. Cayenne pepper is the other strong order that acts as the best rat repellent for cars. 

Use Electronic Deterrents

Today’s market offers several useful electronic repellants for rats and other rodents. Some electronic deterrents use flashing lights, others are ultrasonic, while some cause vibrational disruptions to deter rats. Some of these deterrents will buzz loudly when they sense any motion around the vehicle.

Other deterrents send out unpleasant sounds that are only heard by the rodents. The main advantage of this type of deterrent is that you do not have to keep on respraying every time you park your vehicle. Some electronic deterrents are solar-powered, while some you can plug into a wall socket or on the vehicle’s lighter receptacle.

Using Biological Deterrents

Most people advise you to keep a cat to discourage rats from your vehicle. This may seem reasonable if your feline has the right hunting disposition and instincts. However, you should be careful they also don’t cause harm to the vehicle. The cats may scare away the rats but leave markings on your vehicle.

Using Light to Deter Nesting

As we discussed above, rats love to nest and stash food in dark places where they can eat later. Some of their preferred areas in your vehicle are the air filters or engine components. You can simply discourage this by keeping your car hood and garage lit. During the day, ensure your vehicle’s interior gets direct sunlight.
