Some cities have a big pet store that sells all sorts of stuff for pets. If it were me I would go to one and see what they recommend.
The above picture of Hartz ultra guard plus looks promising, but before I would spray down some place that I would come into contact with I would do some research on the internet to see if it was something too strong to be around.
What ever you use, you might want to roll down all the windows for the first few minutes of driving when you first get in the car, and then use the vent mode for the heating/AC to bring in fresh air while you drive.
