The aim of this study was to determine whether bank voles Clethrionomys gla- reolus (Schreber, 1780) could be trapped by the odour of other individuals as opposed to using food as bait. A line of 100 snap traps was set at 2 meters interval in a forest. Odour bait was prepared of polyurethane foam cubes (1.5 cm3) on which few male and female bank voles were kept in a 2 litre glass jar without food and water (to prevent the transfer of food odours to the bait). Traps with even numbers were provided with the odorous foam cubes (changed every two days) and traps with odd numbers were provided with new foam. Trappings were carried out in two series in autumn, the first for 14 days and the second for 10 days. Fifty five bank voles (mean: 2.50 ±2.11 per day) were trapped in traps baited with odour foam and 14 (mean: 0.64 ± 1.36 per day) in traps without odour, the latter during the first three days of both trapping series (p < 0.001). There was no difference in the number of individuals caught on the first and second day after placing the bait with odour.
