I have a 6' indigo snake that lives in my attic. He has been there for about 6 years (that i know of) - he likes to shed on the attic door. Hopefully I won't open it while he is in process. I doubt I have too many critters because of him. Maybe you should get one of those, lol. I had to have a new AC unit put in last week. The workers weren't too happy when they caught a glance of the snake.
