I will have to try that the next time I have a problem with raccoons. The last time I could not get rid of them, and I had to call a raccoon removal service for help. They did a great job, but I don't want to keep calling them any time I have a raccoon problem on my property.
There is a lot of advice you can find online about stuff like this, and it rarely works. I hope that the thing you said works for me too.
