Deer, rabbits, voles, and birds may attack fruits if given the chance. Repellents may keep the animals away, but the surest way to protect your fruiting crop is by exclusion. In the cases of deer and rabbits that means erecting a fence or other enclosure to protect the plants.
Voles chew bark of fruit trees and shrubs over winter. Place a hardware cloth ring around the trunk of fruit trees or around entire shrubs over winter to protect them from voles. Stop birds from stealing or damaging ripe fruit by covering the crop with bird netting.
