A few days after Termidor treatment around the perimeter and under the foundation, we had a trench 5 feet deep dug up along the foundation walls to install a french drain. Does that mean that we dug out the Termidor and it will not be effective?
Yes if the soil was disturbed, removed, or displaced after Termidor SC it could change effectiveness of barrier.
