Market Segment Overview - Pocket Gophers

Overview

Rozol® RTU Field Rodent Bait is a commercial product that may be used for the control of Pocket Gophers (Thomomys spp. and Geomys spp.) on lawns, golf courses, rangeland, and similar non-crop areas.

Areas of Use

Pocket gophers throw out low, fan-shaped mounds on either side of their underground burrows. These lateral tunnels come to the surface are on the flat side of the fan, and the entrance holes are plugged with loose soil.

Damage

Pocket Gopher damage to turf

Irrigation / Slope damage

Pocket Gopher damage to underground wiring

  • Pocket gophers can cause major damage to grassland, lawns and golf courses.
  • An active infestation can reduce forage capacity up to 49%.
  • Pocket gophers can damage sloped drainage, underground utility cables, irrigation lines and drip tape, undermining foundations, levees, and roads leading to soil erosion, slope failure, “wash-outs”, as well as substantial crop and farm production losses.
  • Gopher mounds damage farm implements, slow harvesting and can injure livestock.
  • Gopher digging brings fresh seeds to the surface, facilitating infestations of noxious weeds, which may be toxic to livestock.
  • Annual crop losses by pocket gophers to grain and alfalfa fields in Canada are estimated to be between $15 -$30 million.1

Helpful Application Tips & Tools

Applying Rozol Pocket Gopher Bait Using a Spoon

Step 1. Open the burrow.

Step 2. Bait the burrow

Step 3. Close the burrow

With a long-handled spoon, carefully remove the plug on the flat side of the fan. Carefully insert 15 grams of bait as far down into the hole as possible. Replace the soil plug to close the burrow, with care so that the bait is NOT covered with soil.

Probe Application:

Probe Baiting

Probe Application Diagram

Using a metal rod, probe 15-30 cm deep (6-12 inches) to locate the main tunnel. Consult diagram for location to probe. Drop 15 grams of bait into the tunnel and cover the hole so light will not enter the tunnel system.

Make 2-3 bait placements per burrow system. Bury dead animals and spilled bait found on soil surface immediately. Maintain a constant supply of bait in the burrow system for as long as there is pocket gopher activity. Do not apply bait on the surface of soil.

The right and the wrong ways to use a probe for placing pocket gopher bait are shown. Bait should be placed loosely in the main runway - not in the laterals or embedded in the bottom of the runway.

Note: Replace contaminated or spoiled bait immediately. Collect and dispose of all dead animals and unconsumed bait properly. To prevent reinfestation, eliminate food, water and harborage as much as possible. If reinfestation occurs, repeat treatment. Where a continuous source of infestation is present, establish permanent bait stations as necessary.

Only to be used by certified pest control operators, farmers and persons authorized in government-approved pest control programs.
