No difference in field control of pine voles was found be¬tween 3 different pellet sizes broadcast at either 5.6 kg/ha (5 lbs/.p acre) or 11.2 kg/ha (10 lbs/acre) for either Volid or ZP Rodent Bait . Comparison of the 18 Volid plots with the 18 ZP Rodent Bait plots showed a statistical difference in animal control between these materials of 95% and 85% respectively. Place packs of Volid or ZP Rodent Bait were opened at approximately 95% of the active sites. Since about 5% of the sites were active by the apple indexing, we believe a low but residual population existed which could repopulate the area. Good con¬trol was achieved using these products.
