First of all, I keep my car clean. No food rotting in the back seat. I have an ant problem. Fortunately, they mostly stay on the outside of the car. This makes me wonder if it's the Zipwax that I use. I've tried ant "traps" where they take the poison back and they all die. Hasn't worked. Ideas? I'm not gonna use Zipwax anymore and see if that's what attracted them. Has anyone had a similar experience?
