I purchased those organza bags back during the winter...I'm having very good success with them against the birds, they just don't seem to want to peck at those bags...I noticed they also keep small insects away from the figs during the vulnerable ripening cycle, especially when the eye of the fig would give easy access to them...the organza material is woven with a very tight mesh...they are also reusable throughout the entire season. (maybe even next year too).
