| Assessment timea | Mean tick countsb [n] (control/treated) | Efficacy [%] (I. ricinus) |
|---|---|---|
| Week 1 | 34.2/0c (34.3/0) | 100 (100) |
| Week 4 | 40.9/0c (41.0/0) | 100 (100) |

aEfficacy assessment either 48 (±2) hours after treatment (week 1) or 48 (±2) hours after re-infestation (week 4, 8 and 12)
bGeometric mean results; in parenthesis () the arithmetic mean results are given
cLog-transformed live tick count in the treated group is significantly different from negative control (p < 0.0001)
