A system and method for gassing an animal, such as a gopher, within an underground burrow (52) comprises a probe (2) having a shaft (6) with first and second ends (8, 10) and a tip (14) on the first end. A shallow hole (54) is formed in the ground with the tip of the probe to locate the burrow and dry solid chlorine material is introduced into the burrow. Water is then poured into the hole onto the dry chlorine material to generate chlorine gas and the hole is closed to seal the gaseous poison within the burrow, thereby allowing the gaseous poison to expand throughout the burrow and gas the animal. Since chlorine gas is heavier than air, the gas will naturally follow the gopher to the deepest recesses of its underground dwelling, killing the gopher without endangering agriculture or other life above the ground.
