How to deal with an ant problem in my car?

Got in my car this morning and the inside is swarming with ants, I don’t even know why. I never leave food in there and I haven’t spilt anything. I don’t know where they’re coming from either. Would vacuuming and wiping down the inside get rid of them, or would bug spray/bug bomb be more effective?
