Boy, I wish I had read about this before we went! We were on the Aug. 26 Wonder (between Charley & Frances ~ beautiful weather!). 3 days later, we got back into our van, which hubby parked under a tree, near a parking island. We noticed an ant, then a few more, 10 minutes away from port, we realized we were INFESTED, and they were biting us! We found a walgreens fast, got some ant spray, drove across the street to a gas station with a vac, and took EVERYTHING out of the car & sprayed & vacuumed. (There were thousands of ants, especially under the mats & in the crevices!) At this point, DH said he noticed a sign when parking not to leave any open containers of food, or you might return to a vehicle infested with ants. We found a bunch of crumbs, french fries, skittles, etc. Obviously enough to cause them to want in.
From now on, we'll know to park out in the open, spray the tires, and pick up or vac every last crumb!!!
