Don't put food in your trash. Compost it. It's so nice not having to worry about raccoons in my trash. Before I composted, they were there every week. Once I forgot to take the middle section out of the pizza box. There must have been cheese and grease on it because a huge raccoon got it. My husband heard it on the side porch. He turned the light on and it was the fattest raccoon he had ever seen. He calls him King Coon (after King Kong, for clarification). Our neighborhood must be part of his nightly rounds, but that was our only trash visitor in a decade.
