"We heard they have been shooting them," Herrighty said. "But we're asking everyone not to do that. We want to let the USDA try to handle this."
He said the pigs are very bright and, if they learn they are being hunted, may become nocturnal and disperse. But that may already be starting to happen. The USDA initially found no sign of the pigs in the White Oak Branch area until hunters quit for the winter season.
Other states with relatively new populations, such as Michigan and Pennsylvania, are enlisting hunters, trappers and any other means they can to eliminate their hogs. But New Jersey is more hopeful.
"We are fortunate, in one regard, in that New Jersey is among a very few states where the population is small enough and not dispersed that we should be able to eradicate them," Herrighty said.
