Poisoning is a cruel way to dispose of unwanted animals. It usually is a protracted death during which the animal dies in agony. The “poison of choice” for prairie dogs is aluminum phosphide pellets. The pellets are placed in the burrows which are then stuffed with newspaper. The pellets react with the moisture in the ground and produces phosphine gas. The gas attacks every part of the prairie dog and they bleed internally and externally, dying painfully over a several day period.
