Squirrels love to eat ripe fruit off trees, and fig trees are no exception. You must keep squirrels out of your trees if you want to have any figs to pick and eat yourself. There are many different methods for keeping squirrels away, and they all may not work in your yard. Try different things until something works. Squirrels are smart creatures, so you may need to periodically change what you are doing in order to keep scaring them away.
Put a wire cage around your fig tree. This is only practical if your tree is still small or in a large bucket. Once the tree gets to be more than four feet or so, it is highly impractical.
Put an electronic owl on a post near the fig tree. If you don't have a post, you can place it directly on a branch of the tree. These owls are motion sensitive, and turn their heads and hoot when they sense movement near them. Squirrels are wary of owls, and may leave the fig trees alone.
Set out a bowl of fruit and nuts for the squirrels to enjoy. If you set it away from the fig trees, they may leave the figs alone for the more easily accessible food.
Set traps near the fig trees. Make sure they will not harm the squirrels. Release the squirrels back in to the wild several miles from your home. You may have to do this many times, several times a week if you have a lot of squirrels nearby. There is no guarantee you will trap all the squirrels in your vicinity, however.
