barry crump, god rest his soul, wrote in one of his books about pest control in new zealand. The pests in question were wild pigs. His solution was putting out potatoes at night in the fields near the forest. In each potato, he inserted a detonator, and retired to the pub, job done. He could relax with a beer, and listen to the distant bangs, returning to tidy up in the morning.
Why not try that?
