Die, Cockroach!
We’d all like to think that this world would be a much happier place without cockroaches, and for the most part, you’d be right. Seriously, what purpose do cockroaches serve for our ecosystem, other than to freak the heck out of unsuspecting people who go downstairs for a midnight snack?
If you encounter a cockroach, fill a spray bottle with water and soap. The soap will make it hard for the cockroach to run, and it will eventually die. Now, all that’s left to do is find a way to get rid of the corpse of the nasty bug, and you’re all set.
