Cornell hackathon winner targets driver ants with pheromone mist

A student team from Cornell took the top prize at the university’s 2026 Digital Agriculture Hackathon with a concept designed to deter driver ants using pheromone-based misting rather than broad chemical control. The project, developed after work with the Jane Goodall Institute, is aimed first at protecting beehives, with the broader ambition of reducing harm to wildlife and agricultural operations exposed to aggressive ant raids.

The idea emerged from a hackathon centered on controlled-environment agriculture, climate-smart agriculture, digital innovation, circular agrifood systems, and One Health. Cornell said 116 students participated in the Feb. 27 to March 1 event, supported by 50 faculty, staff, and alumni mentors. The winning team included veterinary, engineering, and agriculture students, which is relevant in itself: the project reflects how animal health problems are increasingly being framed as interdisciplinary design challenges rather than stand-alone pest-control issues.

According to Cornell, the system is intended to “misdirect” driver ants away from targets such as beehives without causing ecological harm. Team members said the concept was shaped by conditions they observed at a wildlife sanctuary, where gasoline was being poured around cages to deter ants and had to be reapplied, creating obvious fire and environmental risks. One student, Ava Cabble, a DVM student, said they had seen animals whose ear canals had been eaten by the ants, underscoring that this is not just an agricultural nuisance issue but also an animal welfare problem in sanctuary settings.

That background matters because driver ants, commonly grouped within the genus Dorylus, are widely recognized as major pests in parts of sub-Saharan Africa and can be devastating to apiaries. A 2014 paper in Agricultural and Forest Entomology noted that apiaries in tropical Africa are commonly structured to reduce driver ant attack, including hive placement strategies intended to keep colonies out of reach. More recent insect science literature also shows that aggressive ant interactions can disrupt bee behavior and foraging, even beyond direct colony losses. Taken together, that suggests the Cornell team is targeting a real and under-addressed pain point, especially where low-cost but hazardous deterrents remain in use. (beekeeperstraining.com)

Direct outside expert reaction to the Cornell project was limited in public coverage, but Cornell’s organizers and mentors framed the winning entry as a response to a concrete field problem. Taika von Konigslow, an assistant professor in the Cornell College of Veterinary Medicine and a hackathon organizer, said students were pushed to identify “real pain points.” Mentor Edmund Mabaya described digital agriculture as one of the most promising spaces for new technology. Those comments don’t validate the system’s efficacy, but they do show the project was judged in a setting that emphasized practical use cases over abstract ideation. (news.cornell.edu)

Why it matters: For veterinary professionals, this is a small story with larger signals. First, it highlights how veterinary students are contributing to solutions that sit across livestock health, pollinator protection, wildlife medicine, and environmental stewardship. Second, it reflects growing interest in nonlethal pest management approaches that may better align with animal welfare goals and reduce collateral risks from improvised controls. And third, because the team identified beekeeping as an entry market to subsidize deployment in nonprofit or subsistence settings, the concept raises a familiar translational question for animal health innovators: whether a welfare-driven tool can find a viable commercial path without losing relevance for the communities and species most affected.

There are still major unknowns. Cornell’s coverage describes a winning hackathon idea and prototype direction, not a validated product, published study, or regulatory filing. No public evidence surfaced in this search of patent filings, peer-reviewed efficacy data, or announced pilot deployments tied to the project. That means the near-term story is about innovation intent, not proven field performance. (news.cornell.edu)

What to watch: Watch for signs that the concept moves beyond the competition stage, including prototype testing with apiaries, partnerships with conservation groups or sanctuary operators, intellectual property activity, or proof that a pheromone-based system can hold up under real-world field conditions where ant pressure, weather, and cost constraints are all unforgiving.
