Some rodenticides containing zinc-phosphide have been registered in 1998 to control common voles in afforrestations on former agrarian land, an indication which was so far not covered legally but will be now under EU regulations. Some of these rodenticides and others in comparison have been tested for use in bait feeders, i.w. the closed "bait station" produced by THEYSOHN and developed in the Lower Saxonian Forest Research Institute. The testing site in agrarian surroundings was a grassy bank well protected from flooding and densely inhabited by common voles. 8 bait stations per each of the 4 rodenticides (see table 1) have been established along the bank in one row with the different rodenticides altering. Both of the zinc-phosphide poisoned wheat baits have been not sufficiently accepted by the voles, the uptake of the two chlorophacinone baits has been much better on a highly significant level. Lepit-Forstpellets (a pectin wax pellet containing 0,0075% Chlorophacinone) is obviously the most attractive one for common voles in bait stations. From bait stations containing Ratron-Pellets "F" were collected also 300 small grey slugs in total, from others less than 10 in total.
