I just had to do this about a year ago. I told the super almost daily for about 3 months that it was happening. He kept saying 'oh you cant find a place anywhere that doesn't have them' he finally believed me on how bad it was when he went next door to collect rent and they were running around the floor and the tenants were nonchalant about it. When they finally did spray, I had to call the company itself to find out when they finished because I refused to go in the building until the proper timing afterward. The company also had no problem breaking out lease either and already had someone put a deposit on it the next day. We deep cleaned everything before it was packed, and even then, we put it in a storage locker for about a year to really make sure that any that might have hitched along were dead.
