The indoor surface deposition and distribution of insecticides applied as foggers, baseboard or perimeter sprays, spot sprays and crack-and-crevice sprays represent distinct pathways of potential unintentional and unavoidable residential pesticide exposure of children and adults. Fogger, perimeter spray, crack-and-crevice, and spot sprays using registered commercial products were studied using three 5-part deposition plates positioned in unoccupied residences in Riverside, CA. Pesticide active ingredients included permethrin, chlorpyrifos, cyfluthrin, cypermethrin, and deltamethrin. Horizontal distribution factors of 100% (total release fogger in a small room), 50% (perimeter spray), 15% (crack-and-crevice), and 2% (spot spray) were assigned based upon application of selected commercial products by a licensed pest control operator and investigators who participated in these studies. This research reduces uncertainties associated with assessing human exposure following different application methods.
作为雾剂、踢脚线或周边喷雾、点状喷雾和裂缝与缝隙喷雾施用到室内表面的杀虫剂的沉积和分布代表了儿童和成人意外和不可避免的住宅内农药接触的不同潜在途径。在加利福尼亚州里弗赛德的无人居住的住宅中，使用三种 5 部分沉积板研究了使用注册商业产品的气雾剂、周边喷雾、裂缝与缝隙以及点状喷雾。登记的商用产品包括氯菊酯、氯菊酯、氯氟氰菊酯、氯氰菊酯和溴氰菊酯。基于经许可的虫害防治操作员和参与这些研究的调查人员应用选定的商业产品，分别分配了 100%（小房间内的总释放雾剂）、50%（周边喷雾）、15%（裂缝与缝隙）和 2%（点状喷雾）的水平分布因子。这项研究减少了评估不同应用方法后人类暴露的不确定性。
