During a preliminary survey in the summer of 2006, ten South Carolina state park campgrounds were inspected for pest populations of Linepithema humile, the Argentine ant. Based on our results, three campgrounds were selected for more detailed investigation to ascertain the impact of L. humile on campgrounds and visiting campers. Within the three parks, ten 900 m2 sites were selected for detailed observations between July and October 2007. Each site selected contained between 17 and 378 trees. All trees within each site were observed for the presence or absence of L. humile trails. Sites at each campground were inspected four times, one day a month, both in the morning and evening, for a total of four months. By determining the presence/absence of L. humile trails, the percentage of trees infested in each park was calculated. Campers were also surveyed on their attitudes and control practices of persistent trails of L. humile. These data were used to help park personnel develop flyers to educate park campers about Argentine ants and to develop improved control strategies.
