You can get rid of ants in your car by removing all food sources, deep-cleaning the interior, washing the exterior and breaking any pheromone trails that lead ants inside. Traps, sprays or natural repellents can help if the infestation is more stubborn.
Ants are usually drawn to crumbs, spills or sweet residues left behind in the cabin. Once one scout ant finds food, the rest follow. A quick, thorough clean paired with a few targeted steps makes it far easier to remove ants and stop them from returning.
Below, you’ll find the main reasons ants show up in cars, how to remove them and the steps that help prevent repeat infestations.
If you’ve spotted ants crawling across your dashboard or seats, you’re probably wondering what’s drawn them in. In most cases, the answer is simple: food.
Even small spills, snack crumbs or empty drink containers can attract ants. Just a tiny trace of sugar or grease is enough for one scout ant to leave a scent trail, inviting the rest of the colony to follow. If the food source is reliable, ants may even decide to nest inside your vehicle, where it’s warm, safe and sheltered from the elements.
Even after you’ve cleaned out visible food, ants might keep coming back. This can happen if they’ve already marked your car as a food hotspot or are seeking shelter during extreme weather.
No matter the cause, it’s important to act fast before a few ants turn into a full infestation.
Ant infestations in cars are more common than you might think, especially in Australia’s warm climate. Knowing which species you’re dealing with can help with removal and prevention.
Here are the three most common ant types found in Australian vehicles :
● Argentine Ants – These ants build large colonies and are often drawn to sugary spills. Once inside your car, they can quickly contaminate any exposed food.
● Coastal Brown Ants (Big-Headed Ants) – Frequently found in coastal regions, they’re attracted to a range of food types and can invade vehicles if crumbs or residues are present.
● Black House Ants – Small but persistent, these ants often nest in cracks and tight gaps. Without quick action, they can rapidly multiply inside your car.
Fortunately, all of these ant types can be managed with a few smart cleaning habits and timely treatment.
The key to effectively eliminating ants from your car is identifying where they’re coming from.
Start by thoroughly inspecting your vehicle for any potential food sources, such as crumbs, drink spills or forgotten snacks. Pay extra attention to areas like the seats, floor mats and between seat cushions, as these are prime spots for attracting ants.
Next, check all possible entry points. Ensure that door and window seals are intact and inspect air vents, as ants can easily slip inside through these gaps.
Understanding where and why ants are entering your car will help you take the right steps to get rid of them for good.
Getting rid of ants in your car depends on the severity of the infestation and the condition of your vehicle, but the following steps are effective in most cases.
The first and most crucial step in eliminating ants from your car is to thoroughly clean the interior, ensuring it’s free of any potential food or drink sources that might be attracting them.
Begin by removing all litter, wrappers and leftover food from your vehicle. Follow this by vacuuming every part of the interior, including those hard-to-reach spots where ants may be hiding.
Ants only need tiny crumbs to find their way into your car, so make sure to pay extra attention to places like the sides of your seats where crumbs often settle.
Top Tip : Use different vacuum attachments to get into every corner and crevice. For a deeper clean, you can also turn to professional car washing and detailing services available at Star Car Wash.
After cleaning the interior, it’s essential to give your car's exterior a thorough wash. This step helps eliminate any sticky food or drink residue that could be attracting ants and disrupts the pheromone trails they use to guide others into your vehicle.
Top Tip : Don’t forget to clean the undercarriage and around your tyres, as these areas are common entry points for ants. For the best results, visit your local Star Car Wash, where our expert hand car wash specialists can provide a detailed clean.
If you often park near an anthill or under trees, one of the simplest and most effective solutions is to move your car to a different location. By doing so, you can disrupt the pheromone trail left by ants, preventing more from joining those that have already made themselves at home in your vehicle.
If the previous steps haven’t eliminated the ants, it might be time to use ant traps or sprays to tackle the infestation.
For ant traps, place them under seats or in areas where you’ve noticed the most activity. Keep checking and replacing the traps as needed until the infestation is gone.
When using ant spray, make sure it's safe for vehicle use to avoid staining upholstery or the interior.
Top Tip : If children or pets frequently travel in your car, opt for a child- and pet-friendly ant spray to ensure their safety while effectively dealing with the ants.
If you prefer to avoid chemicals, natural repellents can be an effective alternative. Wipe down your car's surfaces with a citrus-based solution, as ants dislike the scent.
Peppermint or tea tree oil can also serve as a natural deterrent when applied to entry points. Just remember to dilute the oils according to the instructions before use to ensure they’re safe for your car’s interior.
If you’ve spotted an ant nest near your driveway or parking area, addressing the source of the infestation can prevent ants from returning to your car. Consider DIY methods for nest removal or, for more effective results, consult a pest control expert to handle the situation.
The most effective way to deal with ants in your car is by preventing them from entering in the first place. Here are some tips to help :
● Avoid eating or drinking in your car – Spilled crumbs or drinks are often what attract ants. By avoiding eating or drinking in your car, you reduce the chances of food remnants that might invite ants inside.
● Regularly clean your car interior – Keeping your car clean is key. Regularly remove rubbish, wrappers and crumbs to deter ants. Additionally, wash the car exterior to remove any sweet sap residue or spilled liquids that may draw ants.
● Maintain your seals – Ensure that door and window seals are intact and functioning. Properly maintained seals reduce the risk of ants entering through gaps.
● Close air vents to the outside – Closing air vents helps prevent not only ants but also other insects from entering your vehicle.

What’s the fastest way to get rid of ants in a car?
Remove all food, vacuum thoroughly, wash the exterior and move the car away from the ant source. This usually breaks pheromone trails within a day or two.
Do ant sprays damage car interiors?
Some can. Look for sprays labelled safe for vehicles or choose child- and pet-friendly options. Test on an inconspicuous spot first.
Can ants cause damage to a car?
They typically don’t harm the mechanics, but they can nest in vents, wiring gaps or upholstery, creating ongoing mess and distraction while driving.
Why do ants return even after I’ve cleaned the car?
If a pheromone trail has already been established or ants are seeking shelter from weather changes, they may keep coming back until the trail is disrupted.
Is it safe to use natural oils like peppermint inside a car?
Yes, as long as they’re diluted properly. Undiluted oils may stain surfaces or create strong scents that linger.
By now, you should have a clear understanding of how to get rid of ants in your car and prevent future infestations. Avoiding eating and drinking in your car and maintaining regular cleaning are key steps to keeping ants at bay.
