Carpenter ants
don’t eat wood…
But they can still destroy a pole.
They’re attracted to areas with surface moisture — marshes, wet ground, locations where conditions stay damp but not submerged. They don’t prefer standing water, but they thrive near it.
And when they infest a pole, they don’t randomly tunnel.
They enter through existing seasoning checks near the ground and begin hollowing the pole from the inside out. They follow the path of least resistance, chewing through the softer springwood bands and leaving the harder summerwood behind.
The result?
Uniform internal galleries that can significantly compromise structural integrity — even when the exterior looks relatively intact.
During inspection, these voids can sometimes be felt or heard when boring. But without proper assessment, the extent of internal damage can be underestimated.
Not all pole damage is decay.
And not all insect damage is obvious.
At Exo, we focus on identifying the type of deterioration, how it progresses, and what it means structurally — so utilities can address real risk before failure occurs.
