From the makers of P.C.Q., new Ditrac Ground Squirrel Bait is a non-restricted use product that can be applied within 100 ft. of man-made structures when used with a secured, tamper-resistant bait station. It can be used for the control of the California ground squirrel (Otospermophilus beecheyi) in California, Oregon, Washington, Wyoming, Utah, Nevada, New Mexico, Arizona and North Dakota. Specifically developed to appeal to this squirrel species, the bait is available in a 12-lb. pail or 50-lb. bag, with its active ingredient of diphacinone at 0.005 percent. The formula competes with the California ground squirrel’s natural food sources.
