Which method is often employed to treat termite infestations?

Gas fumigation is a widely used method for treating termite infestations, particularly in severe cases where traditional localized treatments may not be effective. This technique involves sealing the affected area and introducing a fumigant gas that penetrates all wood structures and surfaces to eradicate termites that may be hidden or nested deep within.

The effectiveness of gas fumigation lies in its ability to reach areas and colonies that are otherwise inaccessible. Unlike topical treatments, which only address surface-level infestations, gas fumigation ensures a more comprehensive approach, ensuring that even the most hidden termites are eliminated.

In contrast, while insect traps might help monitor pest activity, they do not directly eliminate infestations. Light pheromones are more useful for monitoring and attracting insects rather than controlling existing populations. Water spraying may not have any significant impact on termites since they can survive in environments with moisture, and it does not target the pest effectively. Therefore, gas fumigation stands out as the most effective and thorough method for treating termite infestations.
