Fumigation is highly effective in eradicating termite infestations, especially for drywood termites that inhabit inaccessible areas within a structure. The process involves introducing a fumigant gas that permeates the entire building, reaching termites in hidden or hard-to-reach locations. While fumigation effectively eliminates existing termites, it does not provide residual protection against future infestations. Implementing preventive measures post-fumigation is essential to safeguard against re-infestation.
