Although Gopher Gassers are not considered organic, we offer these for home gardeners who may be extremely frustrated by their problematic gopher situation. Gopher gassers contain potassium nitrate, carbon, sulfur (all components of gunpowder) and dextrin (a polysaccharide), which when used sparingly, are not harmful to soils. Quick, reliable, effective control of pocket gophers, moles, and ground squirrels. The toxic gas produced will penetrate the air and exterminate the pests or repel them to move somewhere else. Please do not use these for wildlife or near endangered species' habitats.
