Per the Termidor SC label: French drains eliminate water at the footing along a foundation perimeter. They are common in hollow block foundation structures to drain water seeping from the exterior perimeter or underneath the foundation. Soil must be dry before applying to sites with French drains. DO NOT rod through the slab any closer than 24 inches to the French drain to prevent Termidor SC finished dilution seepage and/or damage to the drain or the tiles. DO NOT apply Termidor SC within 5 feet of the sump pump pit and pump. To prevent drainage/seepage from the block into the drain, DO NOT drill through hollow block foundations that border the French drain. Once French drains have been identified and located, apply a 0.06%, 0.09%, or 0.125% Termidor SC finished dilution as follows: 1. Unplug the sump pump. Inspect sump pump pit for water. If no water is present, the treatment can be made provided the sump pump remains unplugged, or 2. if water is in the sump pump pit, unplug the sump pump and remove four cups of water from the sump pump pit. Mark the water level. Wait 10 minutes and check the water level in the sump pump pit again. If the water level has risen, there is too much seepage to perform the treatment at this time. If the water level does not rise, make the treatment provided the sump pump remains unplugged. During application, check the sump pump pit every few minutes for the presence of Termidor SC finished dilution. If detected, stop treatment immediately and remove the contents of the sump pump pit before plugging in the sump pump again. Either apply the removed sump pump pit contents to a labeled site or dispose of the removed contents as directed by this label in the Pesticide Disposal section. Note: For structures with French drains located adjacent to the outside of the foundation, refer to the Structures with Adjacent Wells/Cisterns and/or Other Water Bodies section of this label.
