粘性越强防虫效果越好但同时越容易粘尘失效，尘土大的果园环境下超强粘胶2-3周就被灰尘覆盖失去粘性，反而中等粘性+可更换设计的持效更久

Unverified粘性持久与灰尘失效的矛盾：胶越强初期诱捕越好，但灰尘、落叶碎屑覆盖后胶面失效更快。室外多尘环境应缩短更换周期至2-3周，不能只看标称'可用2个月'88% similarUnverified粘虫板的粘性会因灰尘、湿度和虫尸覆盖逐渐失效，室内环境一般2-4周需更换，粘满或表面结灰即失效，非按颜色褪色判断81% similarUnverified粘胶持效期与灰尘和虫量正相关消耗：多尘环境或高虫口区约7-15天需更换，洁净温室可维持25-40天，标称'持效3个月'多指粘胶未被覆盖前提下79% similarUnverified施工前必须彻底除垢（用草酸或除水垢剂清洁至镜面无残留），否则涂层会包裹旧水垢导致附着力差、几周内脱落，除垢质量比涂层本身更影响持久度75% similarUnverified棘轮机构在沙尘或泥浆环境中容易卡滞或磨损，使用后不清理会显著缩短棘轮寿命，需定期润滑维护74% similar
