The Hawai‘i Department of Agriculture (HDOA) has launched a program offering free treatment for little fire ant (LFA) infestations on residential properties in O‘ahu. The initiative is managed by HDOA’s Plant Quarantine Branch (PQB), which has engaged pest control companies to perform the treatments under PQB inspectors’ supervision. The statewide contract, valued at $1.1 million, aims to treat approximately 580 properties or until funds are depleted. Similar programs for other islands will be announced soon.
Sharon Hurd, chairperson of the Hawai‘i Board of Agriculture, stated, “Thanks to significant funding to combat invasive species provided by the Hawai‘i State Legislature and Governor Josh Green, M.D., the department is now able to conduct a large-scale LFA treatment program for homeowners on O‘ahu by utilizing the experience and expertise of private pest control companies.” She added that treatment plans are also being developed for Maui, Kaua‘i, and Hawai‘i Island.
To participate in the program, property owners must provide their contact information to PQB via email or phone. Renters need landowner permission. PQB will send an LFA detection kit that must be returned for confirmation of infestation. Upon confirmation, inspectors will assess the property and develop a treatment plan if multiple adjacent properties are affected.
The contracted pest control company will apply granular ant baits eight times every six weeks and use products that inhibit LFA growth under PQB guidance. Inspectors will monitor selected properties during and after treatments to ensure effectiveness.
The program is exclusive to residential properties on O‘ahu; commercial properties do not qualify. Residents are encouraged to inspect new plants for LFA before introducing them into homes or yards. Detection kits can be obtained from PQB.
Originating from South America, LFAs are considered one of the world’s most invasive species. They measure about 1/16th inch long and have a pale orange color. Unlike tropical fire ants in Hawai‘i, LFAs move slowly but can cause painful stings leading to red welts and potential blindness in pets.
For more information about this program, residents can contact HDOA’s Plant Quarantine Branch via phone or email.
