Such bait stations must be securely fastened and kept out of pigs' reach. On farmsteads, bait station placement depends on building design and use. For example, in swine confinement buildings it may be possible to attach bait stations to wall ledges, or to the top of pen dividing walls. Never place bait stations where livestock, pets or other animals can knock them over. Spilled bait may be a potential hazard, particularly to smaller animals.
Rodent baits are poisonous to all animals to some degree.
Pigs and dogs are especially susceptible to anticoagulants. Where buildings are not rodent-proof, permanent bait stations can be placed inside buildings, along the outside of building foundations, or around the perimeter of the area. Maintain the bait stations regularly with fresh anticoagulant bait to keep rodent numbers at a low level. Rodents moving in from nearby areas will be controlled before they can reproduce and cause serious damage. Kenneth R.
