ABSTRACT:
A suffocant in the form of a heavier-than-air gas is directed into the subterranean tunnel network of a burrowing air-breathing animal so as to replace the air from such tunnels and suffocate the animals therein. The heavier-than-air gas is preferably odorless, tasteless, colorless and substantially chemically inert, and injected at conditions approximately standard temperature and pressure, so as not to provide a warning to the burrowing animals. The heavier-than-air gas is preferably CO.sub.2, and is injected at a rate of from about 2 to about 10 L/minute. The heavier-than-air gas is injected into a cover member which overlies at least one tunnel outlet in the case of mammals (e.g. gophers) or a plurality of tunnel outlets in the case of insects (e.g. fire ants).
