I'd just get a trash can with a lid and find a simple easy way to fasten the trashcan to the wall so she can't knock it over.
Also ferrets are worse than dogs when it comes to getting into things they're not supposed to, and they are very clever little problem solvers, they find ways to get where they want to go that you never would have even thought of, and then you have to fix that problem.. They're also smaller and can get into more places. For awhile there I was ready to lose my damn mind too. It's easier and takes less of a toll on your sanity, to just proof the house to keep them out of the things you don't want them in, than try to train them not to.
Kids are easier to baby proof the house, and they're a lot easier to 'train'. From my experience even very young children are still smarter than most dogs, they're quicker to grasp 'no'.
