If nothing else, you can keep them out of your apartment with a wonderful little product called Talstar. It's utterly nontoxic to anything without an exoskeleton, and completely fucking lethal to almost anything with one. You can get a pint of the stuff for 50 bucks, and that's probably enough to cover your entire apartment with it for ~3 years. They'll learn damn fast to stay away from the area that makes them melt.
Edit: Scratch that, keep it away from fish. Apparently the scales react to it in the same way insect chitin does.
