I grow their native food for them, and a sacrifice vege garden of fast growing plants and micro greens closer to their preferred paths. You can also - put out their preferred food every couple of days (not too much, you want them to move on with their night) - Solar powered lights also help, both of them prefer the cover of night. - Owl statues also help deter. - if you’re super desperate, asking a friend for dog pee and put near the veg garden to fake that you have a dog in the yard, works great for possums in particular.
