It actually doesn't smell at all in here anymore that the AC is running which makes it hard to figure out what is wrong.

Do you think a few could have gotten out and reproduced (exponential growth after that)?

Are there traps in drains for toilets? I know there is one in the actual toilet so I am guessing that is the only one..
Maybe try turning off the a/c for a bit and giving the house a thorough spring cleaning and see if the smell comes back? Toss out of a few fly strips and see what you can come up with.
