Termidor SC is not known to leech through the soil. You will need to follow the Termidor SC product label which has specific instructions for treating near a well to avoid any contamination issues:
TREATMENT AROUND WELLS OR CISTERNS: Do not contaminate wells or cisterns.
Structures With Wells/Cisterns Inside Foundations: Structures that contain wells or cisterns within the foundation of a structure can only be treated using the following techniques:
1. Do not apply within 5 feet of any well or cistern by rodding and/or trenching or by the backfill method. Treat soil between 5 and 10 feet from the well or cistern by the backfill method only. Treatment of soil adjacent to water pipes within 3 feet of grade should only be done by the backfill method.
a) Trench and remove soil to be treated onto heavy plastic sheeting or similar material or into a wheelbarrow.
b) Treat the soil at the rate of 4 gallons of solution per 10 linear feet per foot of depth of the trench, or 1 gallon per 1.0 cubic feet of soil. Mix thoroughly into the soil taking care to contain the liquid and prevent runoff or spillage.
c) After the treated soil has absorbed the solution, replace the soil into the trench.
Structures With Adjacent Wells/Cisterns and/or Other Water Bodies: Applicators must inspect all structures with nearby water sources such as wells, cisterns, surface ponds, streams, and other bodies of water and evaluate, at a minimum, the treatment recommendations listed below prior to making an application.
1. Prior to treatment, if feasible, expose the water pipes) coming from the well to the structure, if the pipes) enter the structure within 3 feet of grade.
2. Prior to treatment applicators are advised to take precautions to limit the risk of applying the termiticide into subsurface drains that could empty into any bodies of water. These precautions include evaluating whether application of the termiticide to the top of the footer may result in contamination of the subsurface drain. Factors such as depth to the drain system and soil type and degree of compaction should be taken into account in determining the depth of treatment.
3. When appropriate (i.e., on the water side of the structure), the treated backfill technique (described above) can also be used to minimize off-site movement of termiticide.
Termidor SC should be mixed with water and dispersed in a hand pump sprayer. It does not contain an attachment for a water hose on the container.
Fuse Termiticide and Termidor SC are both very good products. They both contain non-repellents so that the pests do not know they are coming in contact with it. Fuse does have two active ingredients, one of them being fipronil, which is in Termidor SC. The other is imidacloprid. Both act in the insects nervous systems, but in different locations. Imidacloprid targets post-synaptic nicotinic acetylcholine receptors in insects, causing over-stimulation of the insects nervous systems. Fipronil acts as a post-synaptic gamma-aminobutyric acid (GABA) inhibitor, also resulting in over-stimulation of the insects' nervous systems. According to the manufacturer, this product could last up to 8 years in the soil. Termidor SC lasts approximately 10 years in the soil. You will treat the same way with both products as well. FUSE is more labeled for wood infesting ants, such as carpenter ants whereas Termidor is labeled for a wider range of ants, acrobat, Argentine, big-headed, carpenter, crazy, odorous, pavement, pharaoh, thief.
Since Termidor SC is a non repellent, overmixing could negatively effect the treatment. We recommend to either add more water or start over using the recommended rate of 0.8 oz per gallon of water.
Termidor SC is labeled to control roaches but it is not labeled for indoor use. We would recommend that you use one of our Roach Control Kits to ensure that you have everything necessary for a complete treatment. Please also look over our Roach Control Guide for more information on treating and preventing roaches.
Termidor SC is applied in a trench and in drilled holes directly around all sides of the structure. It will take approx. 90 days to kill any active colonies depending on their size. You can apply Termidor Foam in the wall voids in the sheet rock to spot treat activity. Please read the article below for more information on treating termites.
Since termites do not usually come within 2-3 inches of the top soil, spraying the top surface of the ground with a termicide such as Termidor SC will not have any effect on Subterranean Termites. Doing a barrier soil treatment around the perimeter of home with Termidor SC will give you a 10 year barrier protection against termites. In the areas where there is dirt, dig a 6x6 inch trench pouring 4 gallons of mixed solution every 10 lineal feet (.8 fl oz per gallon of water) For your garage, porch, patios, or other contiguous slabs against the home where you cannot trench, you will drill holes to ensure the termiticide reaches the soil underneath the concrete. Using a hammer drill with a 1/2" x 18" drill bit, drill holes through the concrete about 2 to 3 inches away from the wall or foundation, and about every 10"-12" apart, only on the seam where the concrete is against the foundation. The deeper the better. Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet. This works out to be a little less than half a gallon per hole. It is difficult to get 4 gallons per 10 feet in the holes, so it is important that you use a long drill bit, at least 18" long so you can bore out enough dirt to hold the termiticide. Sometimes the ground is slow to soak up the termiticide you place in the holes. You may need to fill the holes, then go work on something else for an hour, come back and fill them again, go work on something else.....3 to 4 times to get the proper amount down the holes. Once the holes are filled all you need to do is patch them with a concrete patch filler you can buy at Home Depot or you can use our Trebor plugs that will close the hole with no concrete mess.
