#The invention comprises a method and apparatus that uses pressurized exhaust gases for controlling rodents. The exhaust gases from, for example, an internal combustion engine are compressed and injected under pressure into underground burrows of such rodents. The rodent tunnels fill with a very high concentration of such gases as carbon monoxide from the exhaust within just a few seconds. The pressurized injection of poisonous exhaust in the enclosed burrows as proven highly effective in field trials with preliminary kill rates of eighty to ninety percent.

#The presently preferred embodiment of the invention uses an air compressor powered by an internal combustion engine. The exhaust produced by the internal combustion engine is diverted through a free-flow weldment manifold to a set of cooling coils. Cooled exhaust is routed by the cooling coils to the compression intake manifold that is attached to the intake port of the compressor unit. The compressed exhaust is stored in a pressure tank to be used as needed. Exhaust is released out of the pressure tank through a flexible air hose and injected into the burrows to eradicate underground rodents.

#The exhaust supply manifold diverts the exhaust via a weldment using a pipe T between the muffler and the exhaust port. The exhaust supply manifold has one or more adaptation ports for connection and delivery of exhaust to an appropriately sized cooling mechanism. The cooling mechanism consists of tubing sized, and run appropriately, to reduce the temperature of exhaust passed from the exhaust supply manifold to the exhaust compression intake manifold. The exhaust compression intake manifold receives the exhaust from the cooling mechanism and transfers it through a port of equal size to the intake port of the compression device used.
