SEAWEED POSSUM DETERRENT
This one is worth trying.
Take the end of an old nylon stocking, pack in some sponge material or soak strips of absorbent cloth in liquid seaweed and hang in the trees and shrubs where there is evidence of possum damage. Re-wet when dried. Continue this process until the possums move on. Seaweed is not part of the possums diet so they find the smell offensive. But like all animals some types of deterrents may keep possums away and other possums might not fine the smell repulsive. So you might need to experiment with other chemical brand names.
