Welcome to the Hawaiʻi Ant Lab
The Hawaiʻi Ant Lab, a program of the University of Hawai‘i Pacific Cooperative Studies Unit, is dedicated to increasing knowledge about invasive ant biology, management, and eradication.
What We Do

Research
We study invasive ants and develop new methods to manage them. This is an ongoing process that makes HAL the leading agency on LFA management strategies in the world.

Extension
We educate stakeholders on preventing the spread of invasive ants and provide best management strategies based on our research.

Operations
We survey ports of entry, green waste facilities, nurseries, and other high risk areas for invasive ant species, as well as participate in LFA eradication efforts throughout the State.

Ant Management Class
Once a month, Hawaiʻi Ant Lab conducts a FREE half-day class for residents and other interested persons. This class covers ant management basics from theory to practice and includes sessions on Little Fire Ant biology, how to survey, mixing and using gel baits, and pretty much everything you want to know about managing Little Fire Ants around your home.
Currently, we are holding the class on-line through Zoom on the last Thursday of every month. Register to obtain the Zoom link.
