Pest exterminating method and apparatus

摘要

A method of exterminating gophers uses a pest exterminating apparatus which comprises a tank for storing anhydrous ammonia and a supply line connected to the tank for dispensing the anhydrous ammonia from the tank. The supply line can be connected to a gas valve in a gas dispensing position or a liquid valve in a liquid dispensing position. An elongate wand having a flexible tube mounted on a free end is connected to a dispensing end of the supply line for insertion of the flexible tube into a gopher's burrow. A person holding the supply line is spaced from the ammonia being dispensed due to the elongate wand. In use, the person positions the tank adjacent a gopher's burrow and inserts the flexible tube into the burrow. A lever on the dispensing end of the supply line allows a valve to be opened for dispensing a portion of the ammonia into the burrow. The tank may then be relocated adjacent another burrow.
