Baits, dusts, and aqueous sprays were applied to sewer shafts to control American cockroaches, Periplaneta americana (L). Boric acid and hydramethylnon baits failed to provide consistent control because of problems with mold on the baits and because large populations of cockroaches depleted the bait. Bendiocarb, boric acid powder, and a powder mixture of silica gel + synergized pyrethrins provided excellent control for at least 1 mo, but cockroaches reinfested treated shafts within 3-6 mo. Treatments made in the fall when adult cockroach populations were lowest (about 26%) provided best results. Aqueous sprays of wettable powder chlorpyrifos and microencapsulated diazinon provided outstanding control for at least 9 mo. Microencapsulated and emulsifiable concentrate chlorpyrifos sprays provided greater than 94% reductions for a year.
为了控制美洲大蠊（Periplaneta americana (L)），在下水道竖井中使用了诱饵、粉剂和水剂喷雾。硼酸和氟蚁腙诱饵未能提供持续有效的控制，原因是诱饵上出现霉菌问题，且大量蟑螂消耗了诱饵。残杀威、硼酸粉以及硅胶+增效除虫菊酯的粉剂混合物能提供至少1个月的良好控制效果，但蟑螂在3至6个月内会重新侵扰经过处理的竖井。在秋季成年蟑螂数量最少（约26%）时进行处理，效果最佳。可湿性粉剂毒死蜱和微囊化二嗪农的水剂喷雾能提供至少9个月的出色控制效果。微囊化毒死蜱喷雾和乳油状毒死蜱喷雾在一年内减少率超过94%。
