The Hōlua area of Haleakalā National Park will be closed on Thursday evening July 11, 2013, as park biologists work to control the spread of non-native Argentine ants, officials said.

Park officials say the area biologists will apply a small dose of granular pesticide, which is expected to break down after 24 hours.

According to park officials, the ants prey upon native insects, including the “highly vulnerable” endemic yellow-faced bee, which is a primary pollinator of the threatened Haleakalā `āhinahina or silversword plant.

The area is scheduled to reopen on the evening of Friday, July 12.
