In 1998, twenty-five 4-Poster deer treatment bait stations were deployed on Gibson Island (GI), Maryland, as part of the U.S. Department of Agriculture (USDA) Northeast Area-Wide Tick Control Project. Treatments concluded in June 2002, having achieved 80% and 99.5% control of blacklegged ticks, Ixodes scapularis, and lone star ticks, Amblyomma americanum, respectively. No area-wide tick control was attempted again on the island until 2003, when 15 Dandux-manufactured 4-Posters were purchased by the GI Corporation and operated until the present. Annual flagging at sites on the island and a similar untreated area on the nearby mainland in May and June from 1998 to 2007 has demonstrated that populations of host-seeking nymphs of both tick species have remained at consistently low levels on the island during GI Corporation administration of the 4-Posters, in spite of 40% fewer 4-Posters and increased deer density during 2003-2007.
1998 年，在美国农业部（USDA）东北区域范围蜱控制项目中，25 个 4-Poster 鹿处理诱饵站被部署在马里兰州的吉布森岛（GI）上。治疗于 2002 年 6 月结束，分别实现了对黑腿蜱、Ixodes scapularis 和孤星蜱、Amblyomma americanum 的 80%和 99.5%的控制。直到 2003 年，GI 公司购买了 15 个 Dandux 制造的 4-Poster，并且一直运营到现在，该岛才再次尝试进行区域范围的蜱控制。1998 年至 2007 年期间，每年在岛上的地点和附近大陆上类似的未处理区域进行标记，表明在 GI 公司管理 4-Poster 的情况下，尽管 2003-2007 年 4-Poster 的数量减少了 40%，鹿的密度增加了，但两种蜱的宿主寻求若虫的数量在岛上一直保持在较低水平。
