There are 4 bottles to a case of Termidor SC. For this particular product there is not a lot discount available but we do offer fast, free shipping! We apologize for any inconvenience. Termidor SC is labeled to treat carton nests only away from the structure. The trench and drilling up against the foundation of the structure is very important. Please refer to our termite treatment article for additional helpful information on mixing and application.
Termidor SC can be applied to the soil topically (1 ft up and 1 ft out directly up against the foundation) and in a trench for termite control. There should not be any harm done to any grass sprayed.
Termidor SC can be sprayed twice a year at the rate of 0.8 oz per gallon of water and up to 4 times a year at the rate of 0.4 oz per gallon of water.
If that expansion joint is the only area of activity and Termidor SC was used for the initial treatment, most professionals would just treat that area of localized activity. It is possible the termites there came from a colony deep under the soil surface where they would not have come into contact with the existing liquid barrier. You would treat the expansion joint similarly to how you would treat the foundation, using 4 gallons of solution per 10 linear feet, applying evenly into drilled holes. Instead of placing the holes all on one side, however, you would drill them in a zig-zag pattern along the expansion joint. Please let us know if you have further questions.
Termidor SC if sprayed around structure perimeters for ants and other insects can be reapplied every 6 months. If applied in a trench for Termites, it will bind with the soil and last up to 10 years.
The trench should be filled back with the soil you removed to create it so that it can be treated and create the area termites will go through to contact the Termidor SC. It will last 10 years or more in the soil.
If you are doing a perimeter treatment and there is a basement below grade, then the recommended treatment would involve rodding in addition to the standard 6 in x 6 in trench. A professional company would use a long rod attached to a truck spray rig to inject more termiticide every 12 inches to a depth of at least 4 feet. Since a homeowner does not have those tools, you could use a hollow rod or pipe, or a long drill bit (18-24 inches) to help create space to force more termiticide into the ground, ideally at least what you would use for regular treatment, which averages about ½ gallon of solution every 12 inches.
Termidor SC binds with soil and can stay in the soil up to 10 years. We highly recommend to contact the manufacturer BASF 800-526-1072 since it was applied in an off-label manner.
