Why and How Ants Get In Cars
Spilled Food and Drinks
If you have ants inside your car vent, it is most likely because there is a food source close by.
Ants are attracted to just an empty chocolate wrapper as it will still smell sweet.
Empty soda cans are full of sugar, attracting ants even if the soda has spilled onto the floor.
Always keep your car clean of rubbish and food debris, and any spills need to clean properly asap.
Vacuum even the smallest crumbs and wipe all surfaces down often with an automotive surface cleaner.
Shelter and Warmth
Ants get cold and will search for a warm spot to nest.
Car vents are warm places, especially if you drive often and the car is always warm.
Always check these places for ants. Even if you see one or two, it will mean more are not far away.
They Got Transferred In
If you carry something that was sitting outside and place it into your car and it has ants on it, you might not notice.

How to Get Rid Of Ants In Car Vents
a) Identify the ant species first
Before you try to fix the ant problem, you need to identify the type you are dealing with.
Different areas will have their local variation of ants but most ants will get into car vents searching for food or shelter.
The common ones that like to hide out in cars are the carpenter or the fire ants.
b) Remove sources of food and water
If you have any bits of food in your car, vacuum these out right away.
Even the smallest crumb of food can attract ants. If you have something sticky, these will also bring ants to the car.
Make sure you wipe everything over and remove all food sources.
c) Use temperature control to kill ants
Park your car in the sun. In summer months, the car can reach temperatures well over 120 degrees Fahrenheit, which can kill ants.
If you have ants in your heater vents, then you can either park your car in the hot sun for a few hours.
Or turn the heater on high for ten minutes. This will kill any ants in the venting system and the engine compartment.

Commercial Ant Killers
a) Ant Bait
Ant bait is easily affordable and effective in killing and deterring ants. Ant bait is safer than many other insecticides.

Ants are attracted to the formula, but it is toxic to them once they eat it. The ants take it back to share with the other ants, including the queen.
b) Aerosol insecticide
You can spray aerosols inside a car but the car needs to be kept shut for a few hours for it to suffocate the ants.
Then open the car windows and door to ventilate the car before anyone can go inside.
This method is not as successful as the ant bait.
c) Ant fogger
This one is ideal for the car as it can get into the hidden places that ants like to hide.
An ant fogger will kill the ants inside the car plus kill the ones that enter the car within two months of use.
After use, run the a/c to clean the vents out and air out the car for a few hours.
