Patent ID: 7581349

Claim:
An apparatus for controlling rodents, comprising: means for compressing exhaust gases from an internal combustion engine and for injecting said gases under pressure into underground burrows of said rodents; wherein said rodent burrows quickly fill with a very high concentration of said gases; said means for compressing and injecting further comprising: an exhaust supply manifold for diverting a portion of exhaust gas from said internal combustion engine without restricting an exhaust flow from said engine; wherein a stream of exhaust gas is drawn from exhaust gas leaving said engine based on demand for pressurization and delivery of said exhaust gas by said apparatus; a free-flow manifold for receiving said diverted exhaust gas; a set of cooling coils for receiving said exhaust gas from said manifold; a compressor, wherein cooled exhaust gas is routed by said cooling coils to an exhaust compression intake manifold that is attached to an intake port of said compressor; a pressure tank for storing compressed exhaust gas from said compressor; a flexible air hose, wherein exhaust gas is controllably released out of the pressure tank through a flexible air hose; and an exhaust applicator for injecting pressurized exhaust gas into said rodent burrows.
