Junction Triangle

That seems like a crucial point here -- where there are gardens, there is very likely less garbage. Partly because it is more regularly maintained than an ordinary park, by the gardeners themselves, and maybe even because people are less likely to dump their chip bags and pop cans where things are growing. Maybe I'm naive but it makes sense to me. I have also heard from friends who garden at Dupont that there is no rat problem. In a well-maintained garden, that should be the case. We have a garden in our backyard and there are no rats there either!
