Little fire ants, first found on Oʻahu about six months ago, are continuing to spread throughout the island. The ants are already well established on the Big Island and have been found but were controlled on Kauaʻi and Maui.

Faculty and staff at the University of Hawaiʻi at Mānoa’s College of Tropical Agriculture and Human Resources and the Hawaiʻi Department of Agriculture have tips for identifying and controlling these invasive and damaging pests.

See the College of Tropical Agriculture and Human Resources news release for the steps for basic detection and control. Discover where the little fire ants live, a method for detection and how to get rid of them. The college also offers a free publication Little Fire Ant Products Available for Homeowner Use for download.

More about the little fire ants

Little fire ant, Wasmannia auropunctata, is a serious pest because this tiny ant can easily spread undetected into yards and homes, parks, landscapes, vacant properties and forests.

Little fire ants deliver a very painful sting (similar to an electric shock) to people, pets, livestock and even marine wildlife such as sea turtles and ground-nesting birds. The little fire ants are attracted to eye fluids and typically sting near animals’ eyes, which can lead to blindness due to clouding of the cornea, or keratopathy.

  1. I do believe that the organization who proper from this information would be Hawaiian homes as a litty biry it came up in a community forum regarding how to be rid of these pests. County said there was no feasible way to truly rid or exterminate these creatures and only a possibilty of managing the problem. I have a two part qustion; first is this true and how could this message be relayed to the public to ensure transparency towards public recognition of such an important issue.

    a study, video or attached reseach article on the success of the annihilation of these pests would be greatly appreciated as I can divulge this information to people who are personally affected by the infestation.

    Mahalo and good day.

  2. Wow, Maybe we should start killing the ants at the Campus Center??? The green tables are Full of them. I was gonna set off some bait traps I have at home to kill them since the “Experts/Professionals” can’t seem to do it! :D
