In sticky mouse traps, sprinkle an appropriate amount of white sugar, then place the sticky mouse traps inside the car. Ants are attracted to white sugar and will be drawn to it. You can also place an appropriate amount of mothballs inside the car. Mothballs have insect-repellent properties and can help eliminate ants in the car.

Last time ants got into my car, I used a vacuum cleaner to suck them up for half an hour straight, even their eggs were cleaned out. After vacuuming, I used a hairdryer on hot air setting to blow through the seat gaps—ants hate high temperatures and all ran away. I also sprayed a mix of lemon water and peppermint essential oil on the tires and door frames, the smell made the ants avoid those areas. Now, I check for branches and fallen leaves every day before parking, and I never leave snacks in the car. Oh, and I sprinkled food-grade diatomaceous earth under the floor mats—it’s much safer than insecticides, safe for kids and pets, and kills ants physically without damaging the interior. Remember to close the windows and let it sit for half a day after treatment, the ants will completely disappear.

Have you tried sprinkling cinnamon powder on ant trails? Natural spices work wonders for repelling insects. When I found ants in my car, I removed all the seats to search for the queen. After locating her, I sealed the exit with tape and poured boiling water to completely destroy the nest. Then, I wiped down the interior with alcohol, especially hidden areas like air vents. Now, I always park away from green belts and garbage stations, and keep a few packs of desiccant in the trunk. The key is to ventilate the car daily, as dampness attracts pests. After eliminating ants, remember to check the spare tire well—standing water there is like a hotel for ants.

Directly recommend boric acid sugar water recipe: Dissolve sugar in hot water and add half a spoon of boric acid, soak cotton balls and place them near ant nests. Worker ants will carry the poisoned sugar back to the nest, wiping out the entire colony in three days. If you spot ants, avoid using Raid spray as it can corrode the car roof lining. I learned this the hard way—squeezing orange peel oil to wipe door seams is safer. The key to clearing ant nests is to dismantle the air filter, as they often build nests there. It’s advisable to keep a car vacuum cleaner and vacuum the seat gaps weekly—more effective than any pesticide.

My experience is to control it from the source. Park the car on a cement ground under the sun, as the high temperature will make the ant colony relocate. Use a syringe to drain the accumulated water in the wiper groove, as this is where ants most frequently reside. Purchase a narrow-headed vacuum cleaner to reach into the air filter for cleaning, and dismantle the glove box for deep cleaning when necessary. Always keep a whole block of camphor in the trunk, as the smell will confuse the ants' navigation. Important reminder: Wear gloves during cleaning to prevent ant acid, and thoroughly scald the ant eggs with boiling water to prevent recurrence. Now, I use lemongrass essential oil to fumigate the entire car every month, which serves both as a fragrance and an insect repellent.

Emergency treatment involves turning on the AC at maximum fan speed for three hours. Ants fear the cold and will flee collectively, allowing you to seal the door gaps with tape to capture them alive. For complete eradication, seek professional steam cleaning—high-temperature steam penetrates foam layers to destroy eggs. I personally modified my car seat with a heating pad; setting it to 40°C during commutes forced the ant colony to relocate. I’ve also adopted the habit of using dried coffee grounds, scattering them in cabin corners to repel ants and deodorize. Always remind car washers to thoroughly rinse the undercarriage, using high-pressure water jets to clear ant trails hidden in wheel arches.
