Crews return to Mililani Mauka to check for little fire ants

Pest detection crews returned to Mililani Mauka Thursday to check for little fire ants.

They surveyed a six-acre zone between Auina and Kopalani streets, six months after the area was treated for LFA.

The area included 22 private properties, a green belt area, and the roadside.

Approximately 1,500 vials containing peanut butter were used to collect ants for identification.

“We’re putting down 50 bait vials at each house, covering the front yard, perimeter, around the whole entire yard, then we’ll go into the green belt area, survey back, inside the belt and along the street,” said Derek Arakaki, noxious weed specialist with the Hawaii Department of Agriculture.

Officials say survey results all came back negative.

The group consisted of members from various agencies, including HDOA, Hawaii Ant Lab, Oahu Invasive Species Committee, Hawaii Invasive Species Council, and Oahu Army Natural Resource Program.

Since the detection of LFA in June 2014, the area was treated eight times with pesticides and bait formulas in six-week intervals. The last treatment was conducted in May 2015.

Surveys conducted in February and August 2015 did not find any LFA.

Surveys will continue for several years to ensure that the LFA have been eradicated.
