Abstract	:	Pocket gophers of the genus Orthogeomys and Pappogeomys are major pests in rangeland and agricultural areas throughout Mexico. Control relies on the indiscriminate use of fumigants and poison baits. These controls are applied in a haphazard manner; do not provide long-term benefits and the non-target hazards and public safety risks are perceived to be extremely high. Studies indicate that as a result of reinvasion of treated areas or territory expansion of animals surviving the control procedure, controls relying on removal of animals may be limited unless applied at frequent (every three months or less) intervals.
