ABSTRACT:
This invention concerns a non-toxic method of exterminating dry wood termites, fleas, roaches, ants, weevils and the like by utilizing an inert freezing liquid such as liquid nitrogen as the killing agent. The liquid nitrogen is inserted so as to envelop the colony of objectionable organisms until the environment is reduced to a temperature of at least zero degrees Fahrenheit and maintained at that temperature for between 2 to 5 minutes. This method effectively kills the organisms by crystalizing the innards and freezing the cells, thereby eliminating the need for more dangerous and toxic poisons that are currently being used.
