Irish Spring soap is a great home remedy for repelling raccoons.
The scent of Irish Spring Soap will keep raccoons away because raccoons hate the scent of Irish Spring Soap.
All you need to do is break up some Irish Spring Soap and spread it around areas where raccoons are hanging out at.
You can spread the Irish Spring Soap around your garden to keep raccoons out of your garden as well as they'll smell the soap and find that your garden or any area you put the soap has no appeal to them and they'll scurry away and will likely not come back.
Irish Spring Soap not only repels raccoons but also mammal pests, such as mice, rabbit and deer.
