Why is it that Termidor SC can last 10 years if you use it outside but only six weeks inside?


Termidor SC is made to bond to the soil and will only last extended periods of time when placed into the ground for termite control.  Also, when you treat in a trench in the ground for termites, you are pouring in 4 gallons per 10 feet.  Termidor SC will only last for 10 years when applied in a trench for termites.  When you use Termidor SC as a spot treatment indoors on wood, it will only last for 6 weeks at the most, because it is not made to bond and last on wood, it is meant for soil treatments.  Although, you can use it indoors for spot treatments in wall voids for termites only, you cannot use Termidor SC as a pest control spray indoors.
