Formulated for professional use, Gopher Scram is a safe yet effective option for repelling gophers on large lawns, playing fields, golf courses and more. It's made with a blend of nontoxic, organic ingredients that drive gophers away with a two-prong approach ... making their food source taste bad and giving tunnels and surrounding soil a disagreeable smell. These environmental changes disrupt the gophers' senses and drive them out of the application zone. Use with a broadcast spreader to apply in a radius extending past the infected area by at least 30', sprinkle a small handful of granules directly into mounds and then water the treated area for 20 minutes. Repeat in 14 days and every 30 days after.
