I can't stand cockroaches. I did have a family with a horrible ant problem, which I had no difficulty working around.
Then, I had a patient who had cockroaches living either in or under his vent!!!
I understand they gravitate toward things like phones, radios and microwave ovens because the electricity generates heat. Yes, the RT was aware of the situation, which finally got resolved because she was even more skeeved out than I was.
If you aren't able to get a bug specialist in to get rid of them, remember they hate light, but are specialists at hitching a ride to your house in your stuff. I would bring the absolute bare minimum of stuff in the house with you, and keep it in sealable containers. I'm so paranoid about them, I would change clothes outside my house, too.
If it were me it wouldn't make much difference whether I was grossed out 2 nights a week vs 5 nights a week if I really needed the money, though. Best wishes!
