Cockroaches – please help!

I am a tenant who has been renting a renovated apartment in the lower north shore for a few weeks now (I moved out of my investment property, which I am in turn renting out to a tenant – and if he had these concerns, I would address them immediately!).

I love the place – looks great, absolutely ideal location. But it is infested with cockroaches. As I have OCD, I find this particularly difficult to live with – in fact, if you saw the way I sleep at the moment (for a few hours a night out of sheer exhaustion with every light on), you would think I was insane. The condition report stated no infestation, but as soon as I moved in (the first day) I noticed them and wrote as such on the report.

The agent recommended I try bombs. So did my mother. 'Great,' I thought, 'What an easy resolution!'

Wrong! Four bombs down now, still roaches. In fact, I walked back into my apartment after using another bomb yesterday and one was sitting on the wall above my bed in stark daylight.

I have now bought baits (two varieties), surface spray, 'professional' indoor/outdoor spray, one of those insecticide spray packs that continually sprays into the air at intervals. I have ordered an expensive pest inspection.

I can't live like this any more. I need a resolution quickly, as I actually can't sleep in the apartment and am going to stay at my parents'. What can I do? Can I get out of the lease? I love the place so wouldn't want to do this as a primary option, but I'd rather find a less-awesome place with no infestation.
