We have a 9" 2" rock patio around entire house. The house has a roof with approx 4 foot overhang on 2 sides and 2 foot overhang on the other two sides. The exterior of house has asbestos siding but inside house is covered in wood paneling-half in knotty pine and the other half in rough cedar. We worry about termite infestations because we live out in country and due to all wood inside, etc. Could we use your Spectracide Terminate Termite Detection Killing Stakes since we have a rock patio around entire house? If not, what would you suggest?
