There are a few things you can do to get rid of ticks in a car. First, cover the entire car with a tick-proof material. This includes the seats, door panels, and trunk. Second, use an insecticide to kill ticks. Third, cover the car with a tick-proof cloth or wrap. Fourth, put an insect repellent on your skin when you’re outside and when you’re inside the car. Fifth, keep your windows closed and your air conditioning on all the time while you’re driving to prevent ticks from coming in contact with your skin. Sixth, if you have any children in the car, keep them close to you and avoid playing near cars or open windows.
