Why Control Feral Pigs?

Feral Pigs Are Destructive

Feral pigs in Hawaii have no natural predators, and without an aggressive management program will continue to overrun their environment. They inflict severe damage on native ecosystems by devouring the vegetation, trampling the undergrowth,compacting the soil, and uprooting the tender shoots of growing plants. Feral pigs rototill the soil in search of food and destroy the soil structure. Feral pigs routinely decimate once pristine stands of native forest and create places for standing water tocollect, enabling mosquitoes to breed. Mosquitoes spread avian malaria and pox that kill rare and endangered native forest birds that can only be found in Hawaii.

Many residential and commercial areas abutting forested areas, even in highly populated regions throughout Oahu, suffer significant feral pig damage to lawns and ornamental plantings, costing property owners thousands in damages.

Methods of Managing Feral Pigs

  • Small scale trapping is a useful tool, especially in populated areas; however, this only focuses on individual pigs. Pigs not trapped will become educated about traps and learn to avoid them after one negative experience, making control even more difficult.

  • Fencing is expensive but effective. Control without fences is virtually impossible except with complete eradication. 

  • Shooting from helicopters can be effective in inaccessible areas, but ground shooting is not effective in reducing the pig population unless intense shooting is undertaken on a small isolated and accessible population of pigs.
