What is a realistic effectiveness range for pocket gopher toxic baits?

• A. 5-15%
• B. 10-90%
• C. 70-95%
• D. 60-70%

Answer: (B)

Effectiveness of pocket gopher toxic baits is highly variable because whether gophers take and are killed by the bait depends on many factors—bait palatability, placement near active tunnels, timing with gopher activity, soil conditions, weather, and the availability of alternative foods. In real-world use, you can see very low kill rates if gophers don’t consume much bait, and much higher rates when baiting is done near active burrows under favorable conditions. Because of this variability, a realistic expectation spans a broad range—from about 10% up to around 90% control. That broad range reflects how results can swing from limited to substantial depending on how well the baiting is executed and the environmental context. To maximize success, use fresh, highly palatable bait, place it near active galleries, monitor and re-bait as needed, and adjust for weather and gopher activity.
