Also, the queen and developing larvae would not be affected. The fact that individual carpenter ants can live for well over six months without feeding requires that the galleries of the nest be treated. Residual insecticides usually are preferred, but sometimes volatile or contact insecticides may also be useful to flush out and kill carpenter ants. Under favorable conditions, vapors can penetrate inaccessible areas of the nest that cannot be treated directly, thereby aiding in eradication of the colony. Such insecticides should be injected or flushed directly into the galleries.
