Lotusland Best Management Practices for
Pocket Gophers

In the past Lotusland relied on the use of strychnine as well as trapping for gopher control. The use of strychnine was discontinued because of its extreme toxicity and the regulatory complexities associated with its use. Adequate control of gophers is possible with trapping, if done in a proper manner on a regular basis. It is important that everyone attempting to control gophers by trapping become familiar with the gopher's biology.

1. Regular monitoring of traps is important to successful management of gophers.
2. The use of wire mesh to protect roots of valuable plants in areas with high gopher populations is recommended.
3. Gophers are more prolific during certain times of the year. Monitoring and trapping efforts should be intensified during these times.
4. Cover crops and insectary areas can be home to gophers. When these areas are mowed the gophers are likely to migrate to other areas and their movement must be monitored.
5. Non-restricted gopher bait and smoke flares are used at Lotusland if trapping is repeatedly unsuccessful.

Trapping method using box traps and anise oil:

Tools: Anise Oil
Box trap with wire leash
One branch of cheeseweed (Malva)
Shovel, weeder, or hand trowel
Procedure: Excavate enough soil to fit the box trap flush up against the gopher run.
Anise oil is used as an attractant. Place 2-3 drops on the inside rear wall of the trap on either side of the ¾" hole.
Malva is a common weed with large enough leaves to disguise the triggering mechanism of the box trap and is a favorite food for gophers.
Do not handle the underside of the trap or the bait with bare hands (tweezers or rubber gloves may be used to bait the trap).
A hand weeder is an excellent tool for discovering gopher runs.
Two traps may be set back to back in a main run facing both directions of the run. After catching the gopher(s), the traps may be re-set in the same run because other gophers commonly share the same runs.
Hand trowels are helpful in the final shaping and fitting of the traps against the openings.
Sometimes a small gopher will trigger the trap without being caught but resetting the trap with fresh bait and new anise oil usually gets them.
