Abstract: Burrowing rodents and other burrowing pests are particularly difficult to eradicate, especially around household pets that like to dig up the rodent mounds in pursuit of the animal. This gas distribution device and the method for using the device was invented to increase the effectiveness of introducing a poisonous or repellent gas into the subterranean tunnels created by burrowing animals such as but not limited to mice, gophers, moles, rats, voles, and various insects. The distribution device can deliver large amounts of poisonous or repellent gas into the subterranean tunnels through the gas distribution chamber using supplied air to assist or without the supplied air assistance. By increasing the effectiveness of distributing poisonous gas throughout subterranean tunnels you may eliminate the need to use traps and poisonous bait that could injure a household pet or livestock.
