It’s important to realize that a treated zone is not a “termite barrier,” it only prevents termites from entering your home while you have an inspection. If they do find any, then the treatment will need to be reapplied and inspected again in six months.
Soil treatments are designed with structural aspects of your home (foundations) so that when termites make their way into the house undetected by building mud tubes around them before drilling through those barriers as well; this can be spotted during inspections for annual maintenance purposes – if there’s anything wrong like signs of weakness or decay on structures near where ants were found outside earlier last year.
