  1. INTEGRATED PEST MANAGEMENT - RODENTS Presented by Monty Sullins Vertebrate Pest Specialist Montana Department of Agriculture

  2. Cultural Practices

  3. Cultural Practices Soil tillage/cultivation Crop Rotation

  4. Cultural Practices Irrigation

  5. Cultural Practices Burning / Debris Removal Grazing Management

  6. SHOOTING

  7. Shooting 1. Ground squirrels, prairie dogs, marmots 2. Can be effective on small areas/localized problems 3. Expensive, time consuming ineffective on large areas

  8. TRAPPING

  9. Trapping Types: • Pocket gopher pincher and box traps • Conibear • Live traps • Ground squirrel traps

  10. Trapping Can be effective on small areas …… but labor intensive

  11. DISEASES

  12. Diseases Plague, Tularemia, etc. occur naturally but cannot be used as a managed control

  13. BUILDING REPAIR AND MAINTENANCE

  14. Building Repair & Maintenance Prevents access of rodents into buildings

  15. FUMIGATION

  16. Fumigation Expensive and labor intensive

  17. Fumigation Ignitable gas cartridge: a. General use b. Lighter than air – may not filter throughout burrow c. May be a fire hazard in dry conditions

  18. Fumigation Aluminum phosphide a. Restricted use b. NEW RULES AND REGULATIONS c. Requires good soil moisture d. Used primarily for ground squirrels and prairie dogs

  19. RODENTICIDE BAITS

  20. Rodenticide Baits Zinc Phosphide grain baits • Registered (restricted Use) for controlling all field rodent pests in Montana • Formulated on grain • Must be prebaited in all applications except for voles • Single dose – no antedote • May be spot baited, broadcasted, or used in burrow machines • Special requirements for broadcast application – contact Montana Dept. of Agriculture • Cannot be used in bait stations

  21. Rodenticide Baits Rozol • Anti-coagulant – Chlorophacinone • Registered for controlling ground squirrels, pocket gophers, and voles – NOT prairie dogs • Antedote – Vitamin K • Can be used in bait stations – also Ra,ik Green • MUST follow application instructions completely – 2 applications 2-3 days apart • Spot application only – cannot broadcast

  22. Rodenticide Baits Strychnine • Illegal to use except for pocket gopher control ONLY – applied underground by hand or in burrow machine • Formulated on oats or milo

  23. PREDATION

  24. Predation 1. Rodents are a food base for hawks, owls, eagles, coyotes, foxes, badgers, etc 2. Help reduce rodent numbers but may not be enough to adequately reduce damage

  25. OTHER CONTROLS

  26. Other Controls 1. Oxygen/propane exploders a. Expensive, labor intensive, poor results 2. Gum a. No evidence that it works
