[The reaction of taiga ticks to an attractant. III. The use of attractant-acaricidal granules in a field experiment].

On June 15, a total of 300 granules were placed at 1-m intervals on the sides of a concrete-covered road located along the steep slope of a valley. The number of ticks on 300-m plots decreased from 557 (before the experiment) to 55 on June 24 and to 11 on June 27. On the 200-m control plot there were 256, 280 and 168 ticks, respectively, in the same periods of time. Thus, the efficiency of tick eradication was 91 and 97% on days 9 and 12, respectively.
