Dishes are an interesting thing. Even people who are typically on the neat side often think nothing of leaving dirty dishes in the sink. But even if you've rinsed your dishes off and plan to wash them first thing the next morning, it's not a smart thing to do. Dirty dishes have food stuck to them -- everything from large chunks to small particles to residue you don't see -- and guess who finds your leftovers, no matter how miniscule? Ants, mice and a gazillion other icky creepy crawlers, that's who. Plus, insects like cockroaches are attracted to moisture as well as food, so a dirty, wet pot sitting in the sink is like hitting the jackpot [source: Pest Exterminate Now].
