Raid makes these little fumigator things you guys can use. Chemicals in a little can. Just add water & bugs are dead. I used one in my big Merc because of a wood spider in the trunk. Great thing about them, they leave no nasty residue on your interior like a fogger will.
Just be sure to put something heat resistant under the can-o-killer. I don't think it gets hot enough to harm anything because it sits in a plastic cup, its just a precaution I took to protect my car.
Good luck!
