Making the snow
The CO2 is in a liquid form in the tube and will come out frozen (snow) from the nozzle. About half of the CO2 will become cold gas, blowing the snow forward into the pests hiding places
Killing the pests
Killing the pestsWhen the CO2 snow hits surfaces at normal temperatures it evaporates and becomes CO2 gas. During this process energy is required and this heat energy is extracted from the immediate surroundings. If insects are part of the immediate surroundings the energy is taken from them and extreme cooling results, the water in their cells crystallizes to ice, killing the insects.
