Gopher X Smoke Oil
Gopher X Smoke Oil can be used with your Gopher X devices while exterminating gophers, ground squirrels, moles and prairie dogs. The patented Gopher X device heats the oil up to its smoke point and gives a visual of where carbon monoxide from the exhaust is going.
The visible smoke helps you to ensure that the carbon monoxide is trapped inside the tunnel system. Pick what best fits your needs.
