What will it cost?

Cost can vary from place to place depending on the scale, terrain, habitat type, ease and type of access, the type of tools being used, pest density and whether labour is voluntary or factored into pest control inputs.


Devices

As a rule of thumb, a least two devices per ha will be required for combined rat, possum and stoat suppression. Preferably these should include one trap and one bait station. 

Based on the above, up front capital investment in devices will cost between $50–$200 (depending on tools selected) per ha to establish. Operating and maintaining these tools (baits, lure, gas canisters, poisons, maintenance) will cost between $25–$50 per ha, each year. Devices generally have a lifespan of up to 10 years.

Labour

In terms of labour, on average a field operator can service 60 devices (30 ha) per day. Landowners may do this themselves, or get their staff to. If they contract the work out contract rates can be on the basis of a ‘per device’ servicing charge — usually between $3–$6 per device, per service. 

Rodent control in sheds and buildings is more device-intense and should be costed separately. Devices should be installed at a rate of at least two per shed or one per 20m2 . A mix of traps and bait stations is always best, alternated over time. Up front capital investment in devices will cost between $20–$200 per shed bay/20m2. Operating and maintaining these tools (baits, lure, gas canisters, poisons, maintenance) will cost between $20–$40 per shed bay/20m2 , each year. Labour requirements are relatively limited and can be undertaken as part of routine farming operations.
