根据多年的实践,若想获得理想的灭鼠效果,应注意抓好以下几个环节: 第一,灭鼠前要先进行一次鼠密度调查,摸清鼠情。通过鼠密度调查,摸清各个时期老鼠在各区域间的分布、密度以及活动情况。仓库、商店、住室等处进行鼠密度调查,一般可采用以下两种间接测定法: (一)粉迹法:用惰性粉(如滑石粉)作粉料,用两层纱布将粉料包上,再在调查区域的各个地方,分别靠墙边、柱边或货垛边摆放20×20厘米的木框,将粉料均匀抖撒在框内地面上,厚度约0.5毫米。一般办公室、宿舍面积不足15平方米布粉点2个,超过
According to many years of practice, if you want to get the ideal rodent control effect, should pay attention to grasp the following aspects: First, before rodent rat density survey to find out rodent. Through the investigation of rat density, find out the distribution, density and activity of mice in different regions in different periods. In general, the following two indirect assays may be used: (1) Grit method: using inert powder (such as talcum powder) as the powder material, using two layers of gauze to pack the powder material bag Then, in all parts of the survey area, 20 × 20 cm wood frames were placed on the side of the wall, the column or the side of the cargo pile, respectively, and the powder was uniformly scattered on the ground in the frame with a thickness of about 0.5 mm. General office, dormitory area less than 15 square meters cloth powder point 2, more than
