Our 14-unit slab development had a Termidor SC or Termidor 80WG in-ground treatment in early June 2015. Approximately how often should the in-ground treatment be redone? We are not sure exactly which product was used, but assume it was one of these 2 since both were launched in 2015. They did a perimeter in-ground treatment around each of our three building slabs.
Termidor SC has a residual of 10 years when applied as a termite trench treatment. If active termite colonies are observed after the trench treatment has been done, spot treatments with a 1 gallon mixed solution of Termidor SC or Termidor Foam is recommended. Drill into the wall void or area where suspected termite colony is located and inject the liquid solution or foam into the wall void. Please view our How to perform a Termite Trench Treatment Article and our How to Use Termidor Foam Video for more information.
