There are tiny roaches in my car?

A few days ago, I purchased a 2002 Ford Escape. I went to get into my car the next day and found little roaches (there are like 2 different kinds in there) around the driver's seat, in the back floorboard, and coming out of the gear shift on the floor. I do not want to bug bomb my vehicle. I don't want to risk my baby getting sick if I were to miss some places after cleaning or if the fumes took too long to go away.

I would contact the person that you bought this car from. Did they advertise it as "clean"? Get some Boric Acid (Borax Laundry Detergent) to kill them. Be aware though that it can be harmful if ingested, so not a good idea for your baby. The Boric acid will definitely kill them, but wherever you pour it, make sure to vaccuum really good afterwards.
