The introduced European red fox (Vulpes vulpes) has a significant impact on native fauna and agricultural production. Fox control methods include lethal baiting, trapping, shooting, den fumigation, den destruction and exclusion fencing.
Fumigation of breeding, or natal dens with carbon monoxide (CO) gas is sometimes used to destroy young cubs. Although den fumigation may locally reduce the number of foxes or problem animals, it is not effective as a general fox control method.
Carbon monoxide is a colourless, odourless gas that causes oxygen depletion leading to unconsciousness and rapid death without pain or discernible discomfort. The gas is generated by the incomplete combustion of carbon using sodium nitrate within a fumigant cartridge. CO is toxic to humans; therefore operators using the cartridges must take adequate precautions to safeguard against accidental exposure.
This standard operating procedure (SOP) is a guide only; it does not replace or override the legislation that applies in the relevant State or Territory jurisdiction. The SOP should only be used subject to the applicable legal requirements (including OH&S) operating in the relevant jurisdiction.
