- In this operational period, the LFA ICS team conducted 4 surveys on priority sites on Oahu.
- In addition to priority site surveys, on Wednesday September 10, the LFA ICS team completed additional surveying in Mililani-Mauka. There were 2 residences separate from the current known infestation that were suspect for LFA and required additional surveying to ensure none were present. A team including HDOA PPC, HDOA PQ, HISC, CGAPS, and UF FWS worked with homeowners in the 2 areas to survey the initial residences of concern as well as the surrounding homes. All areas were negative for LFA.
- Full treatments of all residences, greenbelt, and the buffer area of the known Mililani-Mauka infestation were conducted on September 17-19. Preliminary results are encouraging and residents report having significantly fewer LFA in their houses and yards.
- Treatment of the Waimanalo infestation occurred on September 17. During routine monitoring of this site an alate (winged) female was found out in the open. This is unusual in healthy colonies, and potentially a good indicator that treatments are effective. It could indicate that workers have stopped feeding an unproductive queen or that not as many workers are available to bring food in.
- On Saturday September 13, the LFA Outreach Group, in partnership with Waimanalo Resident Tom Grande, conducted a volunteer survey training workshop with 15 participants. This was in preparation for an LFA Community Monitoring Day scheduled for November 1, 10:00 a.m. – 2:00 p.m. On this day, the trained volunteers will survey roadsides near the existing infestation. Additionally, members of LFA ICS team will be on hand at the UH Waimanalo Research Station accepting and identifying any ant samples brought in by residents in the community. There will be a Community Meeting on Wednesday October 15, 7:00 p.m. – 8:00 p.m. at the Waimanalo Public Library presenting information about LFA and handing out free LFA survey kits.
- Little fact about Little Fire Ants: LFA nest both on the ground and high up into the trees. Despite being able to maintain thriving colonies at great heights, they are not very good at hanging on while out foraging, any slight disturbance or breeze can create a rain of ants from the trees.
