This document provides information about carpenter ant infestations. It notes that carpenter ant colonies have a main nest that requires moisture, often located outside or near indoor leaks. Colonies also establish up to 20 satellite nests connected to the main nest by trails. Treatment requires using non-repellent insecticides like fipronil to control the ants via trophallaxis within the colony, as well as installing monitors to detect termite infestation. Organic treatment options using essential oils are also available.
