Whole-structure fumigation is most commonly discussed when drywood termite activity is widespread or hidden in areas that cannot be treated reliably one by one. It is not the same solution as treating a soil-based subterranean termite problem.
The question is not simply whether termites exist, but whether the activity is widespread or hidden.
A contained accessible problem is a different decision from activity across multiple or inaccessible areas.
If a whole-structure approach is recommended, the licensed provider explains preparation, timing, safety, and re-entry.
The shortcut: termites do not automatically mean tenting.
The important question is not “Do termites mean tenting?” It is “What kind of termites are present, and how far has the activity spread?”
Before planning around a whole-structure treatment, confirm the termite type and how widespread the activity is. That inspection is the decision point.
You do not need to become a fumigation specialist. You do need a clear explanation of why this treatment is being recommended for your property.
The provider should be able to explain where activity was found, why localized treatment may or may not be enough, and what uncertainty remains in hidden areas.
Structural fumigation requires preparation and people and pets must leave the treated structure during the process. Exact preparation, timing, re-entry, and safety instructions come from the licensed provider handling the job.
