Sugar ants come into your car in their never-ending search for food. If you don’t have any food leftovers, it’s unlikely they will stay for long, but if they find what they want, car infestation is most probable. The first step is to clean all of your car, including tires and wheels. Throw away any food packaging or any other boxes and bags you can find. They may seem clean, but ants can smell a lot of things we don’t. Vacuum-cleaning the upholstery is also a must — thus you will eliminate the ants from tiny cracks and holes. If the infestation continues after cleaning, use ant baits (Terro baits are highly recommended).
