"I used to work at an Apple Store and I was amazed at how often people would come into the store with MacBook Pro issues; we'd open it up in the back and find little roaches, usually dead, sometimes still alive. Immediately pack it back up and return to them because it's considered a biohazard and unserviceable at that point. They tend to like warm electronics.
Roaches are everywhere, you really gotta maintain cleanliness and never let them become a problem inside your home or you're screwed."
One thing your bug guy won't tell you is you can buy these things called "Gentral" disc on amazon and put them every where they stop the roaches from breeding
