I'd say don't worry too much about bringing roaches to your new place, because they probably have roaches there already. Boric acid usually works really well for me, but earlier this year we had a problem with lots of the little bastards that just wouldn't go away. I bought bait stations and traps, which didn't completely solve the problem, assuming they did anything at all. Then I got the kind you squeeze out of a syringe and put some of that around the apartment where we saw roaches. That's the last we saw of the little vermin. Gone in 24 hours. I think that was either D-Con or Raid.
