Carpenter ants, known for their ability to excavate wood to build their nests, indeed do not pose a direct health risk to humans in the way that pests like mosquitoes or ticks might, by transmitting diseases. However, their impact can be far from benign, especially when it comes to the integrity of wooden structures in homes and buildings.
Structural Damage From Carpenter Ants
The primary concern with carpenter ants is the structural damage they can inflict over time. Unlike termites, carpenter ants do not consume wood but remove it to create galleries for their nests. This activity, especially if unchecked, can weaken the structural elements of a building. The damage often goes unnoticed for long periods, as these ants prefer to work within the wood, leaving the exterior surface intact. Over time, this can lead to costly repairs and, in severe cases, structural failure.
Carpenter Ants Biting and Discomfort
While carpenter ants are not aggressive towards humans, they can bite if they feel threatened. These bites can break the skin and might cause minor discomfort, including a slight burning sensation due to the formic acid they can release. However, such instances are rare and generally not a significant concern for people.
