Which alternative treatment can be applied if soil treatment fails to control termites?

Fumigation is an effective alternative treatment for controlling termite infestations if soil treatment methods do not yield successful results. This method involves sealing a structure with a protective cover and then introducing a gas that penetrates all areas within the structure. The gaseous pesticide effectively eliminates termites in walls, wood, and other hidden spaces that may not be accessible through conventional treatments.

Fumigation is particularly valuable because it can address extensive infestations that soil treatments might miss, especially in areas where termites have established colonies within the wood itself. The thoroughness of this treatment ensures that even deeply imbedded termites, which are often difficult to reach through other methods, can be addressed.

While insect growth regulators and termite baits are viable methods for managing smaller infestations or as part of an integrated pest management strategy, they may not be as effective for serious or widespread infestations. Physical barriers can prevent infestations but do not address existing problems. Fumigation stands out as a comprehensive solution in cases where other therapies have failed to achieve acceptable control.
