Hey Sapphira Possum poo is good for your garden, like most animal droppings. Though its understandable to want to brush them away, I suggest it's a waste to put them in the trash. The best solution is to add them to your compost - but if you don't have one them you can bury them in your garden. They don't have to go deep, just enough to keep the flies off. Your plants will thank you.
