These tough 3/4" black polypropylene mesh nets protect fruits (strawberries, blueberries, peaches, apples, etc.) and nuts against squirrels, birds and rabbits. While squirrels and rabbits are notoriously good gnawers, these nets rise to the challenge with a barrier that is very hard to chew and if there are other food sources nearby it will be sufficient to deter all but the most determined critters.
