Termidor SC is applied 1 ft up and 1 ft out directly up against the foundation for a crawling insect barrier 2-4 times per year depending on the rate used (see product label for complete mixing instructions). If treating for subterranean termites, the product is applied in a 6 X 6 trench and in drilled holes up against the foundation. Please take a few moments to review our treatment article on How to Get Rid of Termites for more detailed information on a successful eradication program.
Spraying Termidor SC on the surface of soil is not going to offer a protective barrier like the trench and will only work for the general pests that contact the soil surface. Termidor binds to the soil that it is applied to and needs to be used in a trench 6 x 6 inches to offer the best protection. It also does not move through the soil after rain. Termites do not actually contact the surface so it would be best to go back and complete the trench in those areas that have not been done.
You should perform a liquid termite treatment in the ground to get the termites where they are entering the shed. To perform a treatment just as a professional company would do, please read our How To Do A Termite Treatment Article which explains exactly how you should treat your home properly. Doing a treatment like what is described in the article will not only take care of existing termites that you have, but it will also protect and prevent future termites from entering for about 7 years. Even though the article talks about a home, the shed is no different. You should dig a trench around the structure as described in the article below, as well as try to trench around individual supports under the shed if possible, if any exist.

Please let me know if you have any further questions.
When applying Termidor SC as a foam, it is both the chemistry of the foaming agent and the pressurized application from the foaming equipment that generate the foam, so we must have both of these components to create a foam from a liquid insecticide concentrate.
Termidor SC cannot be used to treat fire ants or their mounds. We recommend that you treat the individual mounds (as well as a broadcast) with Extinguish Plus Fire Ant Bait. It will take approximately 1.5-2 lbs per acre and 2-5 TBSP per mound. Please see our Fire Ant Pest Guide for more information and tips about treating for this pest.
Termidor SC can be shipped to homeowners in California for applying as directed to their own property without having a license. You will need a license issued by the state if you plan to treat a property that you do not own or for profit.
We actually recommend, if possible, to apply Termidor in a trench inside the crawl space. You will use the same method as you do around the entire structure.
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 is not a good option for fire ant control because it can only be used on or immediately next to a structure. It is not labeled to be used in the lawn.
Talstar P (Talstar One) would be a good option for chiggers in the lawn. This can be broadcast across the yard.
For fire ants, we would recommend a bait, Extinguish Plus Fire Ant Bait. This can be broadcast across the lawn or applied to individual mounds.
