I've got a couple of raccoons that come on my front porch pretty much nightly and eat my cat's food, run my cat off, make a mess of my porch, and are a general nuisance.
Take the food away.
What Coon does not want nutritious , high calorie, free food? Can you blame them?
(Just leave a warm piazza in the break room and see how long it lasts with the two legged scavengers at your place of work. Or Girl Scout cookies
Take the food away before the Coons decide to rip a hole in your roof and nest in your attic.
A Raccoon ripped off ten feet of my roof before I chased it away.
