Unfortunately, my homeowners association indicates drywood termites in North Florida. They indicate (source's credibility is iffy at best) that spot treatment would be ineffective and wasteful. They are against any spot treatment, despite having to wait months for a fumigation appointment.
In what situations is spot treatment ineffective?
Update: drywood species are airborne (somehow that this is important) in contrast to the subterrainian class. For some reason spot treatment is the go-to treatment for the subterrainian class
