What is the primary treatment for wood-boring beetles?

Fumigation is considered the primary treatment for wood-boring beetles because it effectively addresses infestations that are often widespread and deeply embedded within wood structures. This method involves sealing the affected area and then dispersing a gas or vapor that penetrates all parts of the wood, ensuring that hidden beetles and their larvae, which might not be reachable by other treatments, are eliminated. Fumigation is particularly suitable for severe infestations where traditional localized treatments may not adequately control the problem.

Localized treatments with insecticides can be useful for surface infestations but often lack the reach required to eliminate beetles that dwell deep within the wood, making them less effective for widespread issues. Liquid nitrogen application can kill insects by freezing them, but it may not be practical for larger or complex infestations. Deep cleaning and sunlight exposure can help with prevention and management but are generally less effective at eliminating an existing infestation compared to fumigation.
