Under what circumstances is it appropriate to retreat a home for termites?

Retreating a home for termites is primarily warranted when there is evidence of re-infestation. Termite treatments aim to eliminate existing infestations and protect the property from future attacks. Despite best efforts, it is possible for new termites to invade an area, particularly if there are conducive conditions present, such as moisture or an abundance of wood-to-soil contact. Evidence of re-infestation can come from sawdust, damaged wood, or the sighting of live termites, and addressing this promptly is crucial to preventing further structural damage.

The initial treatment may have included preventative measures, but if new signs of termite activity are observed, this indicates that the treatment was either insufficient, the barriers were compromised, or new termites have found their way into the property. Addressing re-infestation is vital as it can lead to significant damage if not dealt with promptly.

Other scenarios, such as visible structural damage or simply following the homeowner's request without evidence, may not be sufficient justification for a retreatment. Retreatment should be based on evidence of active termite presence rather than assumptions or damage indicators alone.
