1. Squish the mosquito or insect against the window, but stop the car first or you may squish yourself like a bug on a tree .
2. Open a window and tell the mosquito to leave and pray that the vacuum created will pull the insect out the window at some point. Of course you can help the bug along with your hands.
3. Grab newspaper and roll it up and bash the little insect if you can. If you can't, stop the car and chase him till you get him.
4. Don't have a newspaper? Then stop at a local store and buy a fly swatter...the most used weapon on earth...and bash the bug to death.
5. If the fly swatter doesn't work and we really don't understand why it won't, buy a can of insect spray and go after the mosquito or insect or bug or bee or whatever has taken over the car. Spray the inside close the door so you don't breathe that terrible killing stuff yourself and watch and wait for the bug to expire.
6. Now you can drive again without being attacked.
