Four experimental variants used the following: 1) granules only from a filler (control); 2) those from a filler and an attractant; 3) and 4) those from a filler, an attractant, and a toxicant (permethrin or lambda cigalothrin, respectively). Each experiment used 20 nymphs of the first laboratory generation. 90 and 25% were in contact with attractive and control granules, respectively. Out of the nymphs in experiments 3 and 4 granules, 94 and 100% died. The contacts of 4 sec or more duration led to death. The experimental findings suggest that the designing and application of attractive acaricidal granules in the foci of tick-borne encephalitis and Lyme's disease are promising.

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.
