Rodent warfare

Dear Kitchen Rat(s),
When I first saw you and realized how small and gray and terrified of me you were, my heart softened a bit to the idea of your infrequent visits to our kitchen. I'd knock before entering and give you a moment to scurry from inside the trash bin to what I can only assume is a rat paradise in the wall beneath our stove. I fought against an unnecessary rat genocide and said no to the purchase of poison. But then you got cocky. You got sloppy. You brought friends. Bigger friends. Decidedly un-cute, slow moving, gluttonous friends. You are not paying rent nor contributing to grocery costs, rat, and you are no longer welcome.
Wall fillers have been purchased, new trash bins acquired. The backyard is now on lock-down and bits of blue poison have been distributed.
Our Message:
Keep your filthy paws off our property or suffer the consequences.
There are plenty of restaurants in the surrounding areas to keep you nourished.
There's nothing for you here.
And unless you are smart enough not to consume that delicious looking poison and have armor the likes of this:

I suggest that you bid us adieu.
G'day
