So sorry, LeeAnne. I've had raccoon woes here, myself. Sucks.
There are places you can buy special chemical scents to ward off critters. Fox urine, wolf urine, etc. I thought I had noted the website of one vendor, but I just spent 10 minutes trying to find it with no luck. Try Googling. Or, I got the link from someone here in another thread; maybe he will repost it.
