1988年8月中旬,自贡市檀木林宾馆电工房及其附近出现大量跳蚤,工作人员常常受到袭击。通过现场调查,我们发现跳蚤主要分布在电工房外约50m~2的外环境中,另外电工工作房和值班室(约30m~2)也常能见到跳蚤。我们在室外密度较高的地方停留不到1分钟,发现脚上的跳蚤多达十多只。经鉴定,蚤的种类单一,均为猫栉首蚤。外环境有两个变压器,地下有电缆通道,另外有一个小废品堆。据工作人员讲,电工房附近常有野猫出现,但鼠和狗很难见到。我们首先采用0.05％的溴氰菊酯粉2公斤,重点处理室内的墙根、墙角。然后用0.5％的敌敌畏16公斤喷洒室外地面。喷药的原则是先喷低密度区,再喷高密度区;先喷四周,再歼灭中间的跳蚤,另外沟洞内也进行重点喷洒。最后在室外沿墙根再布10cm宽的药粉带。
In mid-August 1988, a large number of fleas were found in and near the Tan Mu Lin Hotel in Zigong City. Staff members were often attacked. Through on-site investigation, we found that fleas were mainly distributed in an environment of about 50m ~ 2 outside the electrician’s house. In addition, fleas were often seen in the electrician’s working room and duty room (about 30m ~ 2). We stayed less than 1 minute outdoors in areas with high densities and found as many as a dozen fleas on our feet. Identified, a single species of fleas, cats are the first flea. Outside the environment there are two transformers, underground cable channels, in addition to a small waste pile. According to the staff member, there are wild cats near the electrical room, but rats and dogs are hard to see. We first use 0.05% deltamethrin powder 2 kg, focusing on indoor wall roots, corner. Then spray the outdoor ground with 0.5 kg of DDVP 16 kg. The principle of spraying is to first spray low density area, then spray high density area; first spray around, then wiped out the middle of the flea, the other also focus on the spray hole. Finally in the outdoor along the wall root and then cloth 10cm wide band.
