Current improvements in baiting pine and meadow voles


Excellent control of pine voles (Microtus pinetorum) and meadow voles (M. pennsylvanicus) was achieved with several commercially pelletized anticoagulant baits applied as single hand-placed or broadcast treatments. A new pelletized formulation of zinc phosphide (Zn3P2) was shown to kill approximately 30% more voles when compared to another surface-coated 2% Zn3P2 corn-and-oat formulation. Hand-placed cellophane or plastic-packaged rodenticides were effective when placed in vole runways under cinder blocks and split tires.
