Ant update: after nary a sign of ants for 3 days, there are 20+ wandering around the bathroom.

Bait is back out (cleaners had picked it up yesterday and tossed it), and I will probably swing by the grocery store to get peanut butter and make up some protein bait to go out with the sweet stuff. Floor has been mopped AGAIN.

There are days I could just burn the whole thing down. >.>
