That is a difficult and hard place to treat spiders. You can use a contact kill spray such as Sterifab to kill any of the spiders that you see. We recommend that you vacuum and then use D-Force HPX that is labeled for use in automobiles. We also recommend contacting Your Local Cooperative Extension Office for help on which products to use for spiders in your car.
