Aerial baiting


GPS positioning of the drone with precise and consistent bait coverage from pre-programmed mission plans.


Cost-efficient application and logistics of a drone operation compared with helicopter and hand-baiting.


Conduct baiting operations without setting foot on the ground or having to hike through dense forest.


Transport all the equipment easily to project site by plane or boat.

Aerial Baiting By Drone


Our Service

Envico is highly experienced conducting aerial bait applications using drones for the eradication of invasive pests, both including vertebrate pests and invertebrates. Envico conducted the world’s first ever island eradication of vertebrate pests by drone in January 2019, Seymour Norte (184ha) in the Galapagos Islands by accurately dispersing 3,000kg of bait. Since then, Envico has worked in New Zealand and internationally on a number of eradication projects using drones for precision dispersal of bait.


Envico has developed specialist spreaders for a variety of bait dispersal patterns, including full swath, directional swath, trickle and cluster baiting. These spreaders are then attached to Envico’s drones which have been designed and built specific for aerial baiting. These systems typically have a maximum product capacity of 20kg.


By using drones, Envico pre-programs the flight mission based upon accurate 3D models of the target area, thereby allowing accurate flying and baiting around clifflines and over varying topography.


Envico has experience with various bait from different manufacturers, including brodifacoum from PestOff and Bells Labs and 6g / 12g cereal bait for DOC.

The benefits of using drones include:

  • Pre-programmed flight missions provide time for QC before  application starts

  • Precision dropping of bait around sensitive areas

  • Consistent and uniform bait coverage without gaps

  • Accurate flight lines and start/stop points with GPS coordinates

  • Smaller buffer zones required

  • Lower logistical cost than helicopters

  • Accurate data reporting with drone flight data.

Future Developments

200kg drone

As part of New Zealand's Department of Conservation's plan to help achieve a predator free country by 2050, Envico is developing a  specialist aerial baiting drone for landscape scale projects. This includes the hardware and software integration of an unmanned helicopter, combined with a specialist dispersal system for cereal bait, and appropriate regulatory approval process for trials in New Zealand.

Eugenie Sage, Conservation Minister said: 

“Drones have the potential to be a game-changer – in helping remove pests from remote offshore islands, respond to pest incursions and suppress predators on mainland New Zealand. They may become another of the broad range of tools available to the Department of Conservation (DOC) and landholders to manage predators and restore New Zealand’s unique natural landscapes.

“It will look at the feasibility and costs of drone use for predator control, as well as potential savings in carbon emissions from current aerial methods. 

“This Government is supporting innovative Kiwi companies such as [Envico] to develop the technology of the future to bring back our native wildlife,” Eugenie Sage said.
