A few years ago we had a problem annually with returning bats, which made a habit of getting behind our second story window shutters on the house,
and each time within a week there seemed to be a hundred bats underneath. It remained that way for 2 weeks.
Nothing helped until I saw a product in our local Lowe's store called
Stay Away Rodent Repellent.
I knew of course that bats were not rodents, but I read about the product and decided to try it.
I placed a couple of "tea bag"-type units behind the shutters (very carefully) from an open window.
The next morning they were all gone. WOW. The same scenario happened the following year---they came, they formed a "community" behind one shutter,
they stayed about a week before they started multiplying a LOT, so I bought more Stay Away and placed the product again,
and once again to my amazement they were completely gone the next morning.
We also noticed that the squirrels that usually played in our back yard had suddenly disappeared, and didn't come back for about a week after the bats left.
I know again that neither bats not squirrels are rodents, but they apparently dislike the product enough to "leave town".
Actually it has a decent "spruce-like" natural scent, not bad at all.
After three seasons of bats returning to our shutters, we decided to take down those two shutters on the end of our house (weren't that noticeable anyway, decoratively),
so now we haven't had bats return at all for about the last 6-7 years, and I'm sure they won't. Seems they only liked North-facing "shelter".
A neighbor of ours down the street had bat problems too, long before ours, and they spent $2500 to have a pest control company come in to eradicate them.
Not sure if they ever returned, probably not, because after our experience, and knowing what they had gone through with the expense, we told them
about Stay Away and we've heard nothing else since. I'm sure they bought and used it.
Anyway, the point is, if I were you I would get some Stay Away and at least try it----hang some "tea-bag" Stay Aways in the area, perhaps double the number,
and see if it works for Raccoons too. The product would be worth its weight in gold if it does.
All small wild animals have very keen senses of smell, and it just might offend them enough to help you. let me know.
