What specific human infrastructure is frequently nested in by Yellow Crazy Ants?

Electrical switch boxes, meters, and communication conduits

Yellow Crazy Ants exhibit a strong affinity for nesting within human-modified structures, particularly those offering sheltered, concealed spots. A particularly destructive aspect of this habitat preference involves electrical infrastructure. They are commonly found nesting inside or in close proximity to electrical switch boxes, utility meters, and communication conduits. This proximity creates severe risks because their presence, especially when massive swarms occur, can interfere with the equipment. The ants' activities, sometimes involving the secretion of formic acid, can lead directly to short circuits, equipment malfunction, and the initiation of fire hazards, posing a direct threat to infrastructure integrity.
