Which beetle group is least likely to re-infest wood structures?

The Ambrosia beetle is the least likely to re-infest wood structures due to its specific life cycle and behavior. Unlike other wood-boring pests, Ambrosia beetles typically do not infest healthy, living trees but are more commonly associated with dead or dying wood. They introduce a symbiotic fungus into the wood, which they use as a food source for their larvae. Once the wood is no longer viable or has been colonized, the likelihood of re-infestation decreases significantly because they do not thrive in the already compromised wood.

On the other hand, powder post beetles and wood-boring beetles can lay eggs in wood structures, and their larvae feed on the wood, which can lead to re-infestation. Termites are notorious for their ability to cause extensive damage by continuously feeding on wood. Their colonies can persist for years, repeatedly infesting wood structures, making them much more likely to cause ongoing damage than the Ambrosia beetle.
