The best of the known methods for control of the chigger vectors of scrub typhus is the application of dieldrin to the ground and low-lying vegetation as a fog or spray at the rate of 2.5 lb to the acre (28 kg/hectare). This has produced a more than 91% reduction in the numbers of Leptotrombidium (L.) akamushi (Brumpt, 1910) and L. (L.) deliense (Walch, 1922) for at least 2 years. Aldrin applied at the rate of 2.25 lb per acre (2.5 kg/hectare) is also highly effective, but less so than dieldrin. Lindane at the rate of about 5 lb per acre (5.7 kg/hectare) ranks third, but offers protection for only about 2 months. Because of the potential hazards to wildlife when such long-acting compounds are used, application of organophosphorous or carbamate insecticides may be used instead in areas where reapplication every few weeks is feasible. Fenthion and arprocarb are promising compounds for this purpose.
控制恙虫病恙螨媒介的已知最佳方法是将狄氏剂以每英亩2.5磅（28公斤/公顷）的用量作为烟雾剂或喷雾剂施用于地面和低矮植被。这已使红恙螨（Brumpt，1910年）和地里纤恙螨（Walch，1922年）的数量减少了91%以上，且至少持续了两年。以每英亩2.25磅（2.5公斤/公顷）的用量施用艾氏剂也非常有效，但效果不如狄氏剂。以每英亩约5磅（5.7公斤/公顷）的用量施用林丹排名第三，但仅能提供约两个月的防护。由于使用此类长效化合物对野生动物存在潜在危害，在可行的情况下，每隔几周重新施用一次的地区可改用有机磷或氨基甲酸酯类杀虫剂。倍硫磷和残杀威是用于此目的的有前景的化合物。
