저도 잘 모르지만 일반적인 이야기로 해보겠습니다. 개미들이 어떻게 차안에 집을 짓기 시작했는지는 잘 상상이 안가지만 일반적으로 개미들은 고무를 싫어합니다. 예를 들자면 개미가 자꾸 작은 쇠봉을 타고 올라오면 거기에 고무줄 하나만 감아 놓아도 왠만해서는 개미가 고무줄을 넘어 올라오지 않습니다. 개미가 어떻게 차 안으로 들어온 지는 잘 모르겠지만 개미가 차에서 내리고 싶어도 타이어를 타고 내려가야 하기 때문에 있던 개미가 다 약에 죽거나 굶어 죽이 전까지는 있던 개미가 제 스스로 다른 곳으로 옮겨가지는 못 할 거 같습니다. 만약 먹이가 될만한 것을 다 없애셨다면 시간이 지나면 점차 없어지지 않을까 싶습니다 (혹시 차를 정기적으로 세우는 곳 위로 개미가 지나다니는 나뭇가지등이 없는 지 보시는 것도 도움이 될 거 같습니다).

I live in South Florida.. where we have all ants known to man, ha ha. The first thing we do is to figure out what kind of ants it is… some like food, some sugar, some wood, some will sting you, etc. Normally the ones that come in the house will eat food or sugar. There is a product you can buy at Wal mart, home improvement stores, hardware stores, etc. That is called Terra… Sometimes it is Terra X. It is a liquid, in a small bottle, packaged in a red and white box. This contains boric acid, which won’t hurt people, animals, or the environment. It will end the ant problem for you. Costs less the $3. You could also make your own using corn syrup and mixing boric acid in it. The way I put it out is this.. I run a day care.. and have pets, so I must be careful. I save small jars.. baby food sized are perfect. Wash and dry them, then punch holes in the lids. Put a few drops of the ” bait ” inside and lay the jar on its side. We were infested last year after the hurricanes … I put them anywhere I saw ants. As I saw less and less I started putting them outside the door ways, and where they were likely to be coming in.. Even in my flower pots out side.. they were building nests there.. no ants now.. Ants hate bay leaves, too.
Boric acid is the best also for roaches.. put the powder out where it will remain dry.
For fleas use 20 mule team borax. and moth balls in the vacuum cleaner. Spray with rubbing alcohol when seen. Drops them dead.
Good luck to you,
