Buildings, sheds and food storage areas form a valuable part of most farming operations. However, they can also attract large numbers of rodents, so ongoing effort is required with a range of tools to reduce trap or bait shyness.


Traps

  • Goodnature A24 automatic resetting traps are ideal for rodents. 
  • Place A24 traps, 10–20cm off the ground, near food sources or on trees near pump sheds. 
  • Replace CO2 gas canisters and lure pumps about every 3–4 months. 
  • Rodent snap-traps can also be used (they are cheaper). Place in small wooden boxes set in similar places to A24 traps. 
  • Lure with peanut butter. 
  • Check regularly every 1–4 weeks.

Bait stations

  • In areas with higher rodent populations, bait stations may be more effective.  
  • Use bait stations that contain the bait, so rodents can’t carry it away and store it. 
  • Work on installing one bait station per shed bay/pump shed or one station per 20m2 for rats. 
  • Pulse Ditrac, Contrac or Pestoff blocks every 4–6 weeks. 
  • First generation anticoagulants (Diphacinone, Ditrac) are not generally effective for mouse control. 
  • Remove old or mouldy bait for careful disposal (check product label for advice). 
  • Ensure stock CAN NOT access bait. 
  • Caution is required in milking sheds to avoid contamination of milk with pesticide residues. 
  • Only MPI approved rodenticides may be used in dairy and food preparation premises. Check with your bait supplier to confirm their bait holds this approval.
