Little Fire Ant (LFA) populations in Hawaiʻi are growing rapidly. In addition to their painful sting, LFAs negatively affect the local nursery, agriculture, ranching and tourism industries. Current control methods primarily focus on ground nesting LFAs and largely neglect arboreal populations residing in tree canopies. 

In 2018, we developed a bait dispersion system for a DJI-1000S unmanned aerial vehicle (UAV) to treat hard-to-reach LFA nests. The system was designed for easy replication to be shared with interested parties. The Hawaiʻi Ant Lab partnered on the project with grant funding from the County of Hawaiʻi Dept. of R&D.
