How to get roaches outta my car?

I drive a used 2009 Honda civic, and there are several roaches in my car. I dont know how they got there but every morning when I got to my car there are roaches all over the dash board/seats/floor. Its disgusting. I manage to kill a few, but those buggers scatter b4 i can get to them. It's also embarrasing, a couple people at work are starting to call me lil roach because they saw a bunch of roaches in my car when they were in the parking lot. It's crazy that when i get in my car they hide, but when im out, they come out like its a party. I am fed up with this, someone please help,
