If you are doing a trench application for termites and there is concrete surrounding the foundation, then holes will need to be drilled all around the home to properly apply the Termidor SC. The holes need to be drilled every 10-12 inches apart, 18 inches in depth to reach the soil beneath the concrete and anywhere from 3/8 inch – ½ inch in diameter. Please refer to our Termite Treatment Guide for a more in depth step by step on how to treat your home for subterranean termites.
