Multiple sources, including Maui County and Maui Now, report that two significant Little Fire Ant infestations have been confirmed in Ha’ikū and Kapalua, prompting an urgent call for community vigilance. The Maui Invasive Species Committee (MISC) is coordinating treatment and outreach efforts for both sites. Property owners are advised to survey their land and avoid moving plants, soil, or green waste between areas without testing.
- A ~20-acre infestation in Ha’ikū’s Uaoa area was discovered May 8, 2026; aerial drone treatments are set to begin this month due to challenging terrain.
- A ~40-acre infestation in the Kapalua Golf and Plantation Estates area was confirmed June 25, 2026, with boundary mapping suggesting it could expand to as much as 125 acres.
- Known Little Fire Ant-infested acreage on Maui nearly doubled, from 260.59 acres in January 2024 to 519.41 acres in July 2026.
- 23 of Maui’s 30 recorded infestations were discovered through community reports, underscoring the importance of resident vigilance.
- Little Fire Ants can spread through potted plants, soil, compost, mulch, and green waste — a direct concern for vacation rental properties with landscaping.
- Ants deliver painful stings causing lasting welts and can cause blindness in pets, posing a guest safety risk.
- MISC offers free property surveys; the County recommends testing at least annually and before receiving any new nursery or plant materials.
- County Dept. of Agriculture Director Rogerene ‘Kali’ Arce urged residents and businesses to use MISC’s free surveys before moving plants or soil between areas.
