We've been having a problem with raccoons using the corner of our patio as a latrine.
Each time I've made this discovery, I've suited up in mask, shower cap and gloves and removed the scat and two inches of soil.
Afterwards, I've also sprayed the area with concentrated mint.
This is an enclosed patio, so only climbing animals can gain access (no dogs). And our neighbors are so close that I can't control whether there's food to attract the raccoons.
How do I prevent them from returning? Is there something I could plant to offend them?
