Q&A Home

Bryan from Westford, Ma writes,

I would like to backfill the application trench it with fresh gravel, is this a good idea?


No, it is not recommended to backfill the termite trench with rock or gravel. Termidor SC is made to bind to soil molecules which allows it to last for 10 years whereas Termidor applied to porous surfaces such as roack and/or gravel will only last and remain effective for a few months.
