How to Manage Pests
UC Pest Management Guidelines
Wild pigs include both domestic swine that escaped captivity and wild boar. Wild pigs are commonly found near in the foothill areas, and they prefer areas of dense brush. During periods of hot weather, they will "wallow" in water or moist soil.
Wild pigs will feed on insects and underground vegetation. This "rooting" behavior can disrupt parts of the orchard floor. Pigs will also create large uneven basins or wallows in moist soil during hot weather. Both rooting and wallows can disrupt the application of irrigation water. If a pig gets tangled up in flexible irrigation equipment, it will pull it out. Pigs can eat lower fruit on the tree.
Wild pigs are considered game animals and fall under the jurisdiction of CA Department of Fish and Game. Pigs can be trapped or shot, but this requires a depredation permit. In some CA counties, the Agricultural Commissioner has trappers who can assist. Fencing can be done but is expensive. Frightening devices can be used for a temporary solution.
