The Montana Department of Agriculture's Vertebrate Pest Program provides the agricultural community and the general public with information on the management and control of many vertebrate species. These are animals that sometimes cause damage to agricultural crops, yards, and gardens. Department specialists are available to provide information and demonstrations of management techniques.

Montana Vertebrate Pest Program Seeks Study Sites for Ground Squirrel Research

The Montana Department of Agriculture’s Vertebrate Pest Program is looking for multiple state study sites with a known abundance of Richardson’s and/or Columbian ground squirrels to evaluate the efficacy of a diphacinone-based rodenticide.

Research locations will participate on a voluntary basis and should be at least 20 acres in size. Sites within 50 miles of Bozeman and/or Lewistown are of particular interest. To learn more, contact Stephen M. Vantassel, Vertebrate Pest Specialist, at 406-538-3004 or svantassel@mt.gov

In-Person Programs

Requests for presentations to groups are encouraged. The program format is usually in the form of slides and display of vertebrate pest control materials. Programs can be individualized to address problems and questions of local concern. Individuals requesting programs are encouraged to suggest topic areas of greatest interest to the people likely to attend.

Field Demonstrations

In field, hands-on field demonstrations of rodent control methods need to be scheduled during optimum control periods for each rodent species. Ground squirrels - spring to early summer; pocket gophers - spring, early summer, and fall; and prairie dogs - late summer to early fall.

Depending on the specialist's schedule, some programs and demonstrations can be arranged on short notice. For best results, requests should be made at least 3-4 weeks in advance. To conserve travel and time, it is helpful if counties in an area coordinate training to make effective use of the specialist's time.
