One Quart of the Gopher X Smoke Oil.
This blend of oils can be used in the Gopher X Extermination Device as a carbon monoxide warning agent. If you see smoke coming from a tunnel system then you can stay away from the smoke to help avoid contact with high concentrations of carbon monoxide.
The oil can also be used with several types of industrial smoke machines. The unique blend helps to keep smoke machines from getting a buildup on internal parts. Please check with your smoke machine manufacturer before using this oil to ensure that it will be a good fit.
