Complaints from workers suffering from insect bites led to the investigation of three broiler breeder houses. These houses were found to be infested with the hen flea, Ceratophyllus gallinae. Large numbers of adult fleas and larvae were extracted by Tullgren funnel from samples of wood shavings used as nest box material. Lower numbers were extracted from the litter under these nest boxes. A pilot trial using infested nest boxes and floor litter showed good control of adult fleas and larvae could be obtained using a .25% spray prepared from a permethrin water dispersable powder. In more extensive trials the following year, almost complete control of hen fleas and larvae was obtained following monthly treatments of nest boxes with a .125% permethrin spray or a 1% permethrin powder.
工人遭受昆虫叮咬的投诉引发了对三个肉种鸡舍的调查。发现这些鸡舍感染了鸡蚤（Ceratophyllus gallinae）。通过Tullgren漏斗从用作产蛋箱材料的刨花样本中提取了大量成年跳蚤和幼虫。从这些产蛋箱下方的垫料中提取的数量较少。一项使用感染跳蚤的产蛋箱和地面垫料的试点试验表明，使用由氯菊酯水分散性粉剂配制的0.25%喷雾剂可以很好地控制成年跳蚤和幼虫。在次年更广泛的试验中，每月用0.125%氯菊酯喷雾剂或1%氯菊酯粉剂处理产蛋箱后，几乎完全控制了鸡蚤和幼虫。
