Martin's Gopher Bait with strychnine is a treated grain product; only labeled for subsoil applications. Remove burrow plug from flat side of burrow fan or locate main runway by probing with a metal rod or wooden stick. Resistance to probe will decrease when you are in the main runway. Insert 1 teaspoon of bait into burrow system, using a long-handled spoon if necessary. Close tunnel with soil. Do not permit soil to cover bait.
One pound of bait will treat 1-8 acres, depending upon number of burrow systems to be treated. Retreat according to label directions if new gopher activity is noticed.
