WHY DO WOMEN/GIRLS DO THIS???? THEY HAVE TO BE SUPER CLEAN, SUPER HYGIENIC, SUPER STRICT ABOUT THESE THINGS?

That's funny that you think cleanliness is something to complain about. Being clean feels good, and being in a clean environment makes everyday activities better. Also, consider being more careful when eating in your room! Spilled beverages and foods attract ants, not to mention the SMELL of old food/drink.
