We carry a number of diseases and parasites that we can transmit to you through contamination of food and water sources you utilise.  We can cause all sorts of damage to property that result in big bucks from your pockets to fix.  Plus, we will use your roof as our nesting grounds as well as our public bathroom.  It will be unsightly to look at and what happens if this is your business and as your customer is walking in, I gotta go; I miss the ledge and ya, that customer get’s it, my guess they probably won’t be too happy. What if it was your house and same scenario but its your grandmother walking in? I’m not making this stuff up, it’s either happened to you or you have heard a story of someone who got hit because my aim has game.
