Under what condition is complete retreatment for termite reinfestation not allowed?

Complete retreatment for termite reinfestation is not allowed when live termites are not found and treatment history is known. This situation indicates that there is no current infestation, suggesting that the initial treatment was effective or that conditions have changed in a way that prevents new infestations from establishing. If the treatment history confirms that proper measures were taken and there's no evidence of live termites, additional retreatment may not be deemed necessary.

In contrast, the presence of live termites would clearly necessitate some form of retreatment, as this indicates an active problem. Similarly, if only dead termites are found, this could suggest prior infestation but does not imply current activity that warrants complete retreatment. A lack of treatment history also does not preclude the need for retreatment, as it simply leaves the question of effectiveness open without direct evidence of a problem.
