I was going to set up some pie tins this weekend when I was back home, as I was told that should help. Yiu described how it should be set up like my grandmother told me with the pie tins. Before the work week though, I swung over to the dollar store and got some cheap fencing to put along it. I am hoping it helps somewhat while I was gone at work.

The vinegar and coffee grounds sound like a good trick too. Should have some vinegar at home, and I can raid the coffee machine at my grandparents house for the grounds, as I don't drink coffee.
