Dirt filled porches are a great place for termites to live and attack your home or business. In order to stop that source of termite attack, the porch needs to be drilled and liquid termiticide pumped into the soil where it will remain in the porch and be effective for years. Neither a bait system nor a wood treatment system will consistently prevent an attack from a filled porch. Treatment during construction of a filled porch is the most effective, but drilling and treating is the next best thing. Protection is our primary purpose.
