Treat only active burrow systems. To treat a burrow system, locate main runways by probing. Remove the cap from the tip of the applicator syringe and turn dosing ring to mark indicating half ounce. Inject half an ounce of bait (one-sixth of the contents of one syringe) through probe or shoveled open hole at each bait placement location. Make six such placements per burrow system. Cover application holes with sod and soil, but do not allow dirt to sift in and foul or cover bait.
Follow up: Check effects of treatment 4-5 days after bait application by opening and marking burrows in the manner used to check for initial activity. Return 2-3 days later and re-treat all active burrows.
