Richard... thanks for the info. I am going to finish the floors tonight and POR-15 the entire interior tonight. I will give it about 3 days to dry and with NO interior that they can nest in. I will leave the bait traps in it and then possibly drive it around with no carpet or anything for a few weeks up to a month. I am afraid to put the carpet kit, headliner, etc in the car and have them come back. There were so many under the carpet I could not believe it. The floor WAS white and when I pulled the carpet, there were so many ants it literally looked black.
They seem to be in every tiny place and inside the engine compartment, packed in wire looms, between the inner fenders and outer fender, in the wiper motor, inside every electrical part, etc.
I am hoping I can either starve them or this bait works but I do not want dead ants anywhere in the car even if I cannot see them so that is why I am worried and want to pull everything. I also do not want them to hide and come back or get into the house. The car is in my garage right now so that is kind of stupid of me but I did throw 2 bug bombs in the car and garage. I am going to go get 3 more, do one more inside before putting the seats back in, one in the engine compartment and one under the car. They are even inside the chassis!
