Touchdown! Greaser!
Buy cheaper peanut butter. You have to pay extra for the healthy, all natural "no-preservative" stuff.
But even the health stuff should last a month after opening, or maybe only a couple of weeks in a hot, humid hangar, but as has been said, if you aren't catching anything in that time frame, you don't really have a problem.
But mice and rats are smart. You should probably vary you bait occasionally anyway to confuse them. Perhaps a piece of banana (won't last long) or cheese. Who cares if cheese molds; its made from mold anyway.
