SYSTEM AND METHOD FOR ERADICATING BURROWING RODENTS USING ENGINE EXHAUST GAS

摘要

A system and method for eradicating burrowing rodents uses an internal combustion engine running at high speed and zero mechanical load to convert gasoline and air into pressurized carbon monoxide entrained in an inert gas mixture consisting mostly of nitrogen and water vapor. A heat exchanger cools the exhaust gas and provides it to one or more outputs. Respective hoses are coupled to the outputs, with each hose coupled to an injector tube adapted for insertion into a subterranean tunnel in which a rodent may be present. The engine is preferably mounted on a wheeled tubular frame which may be part of a hand truck or a trailer frame, with the frame serving as both structural member and as heat exchanger. The system pumps gas into the tunnel, replacing the existing atmosphere with oxygen poor, CO rich gas that causes the rodents to succumb to a combination of CO poisoning and hypoxia.
