We recommend that you trench the areas where there is soil and drill 10-12" apart and inject the solution into those areas. You will disperse the same amount of finished solution in the drilled holes as you would the trench, 4 gallons of solution every 10 lineal feet. For more detailed information on performing your own termite treatment, please click on the link below.
Termidor SC can be applied in drilled holes every 10-12 inches by using a funnel or a sprayer set on a pin stream setting. The hole needs to drilled deep enough to apply 1/2 gallon of finished solution to each hole.
Termidor SC lasts 10 years when applied as a trench application to the soil only. Please be advised that this product is for outdoor use only.
You will typically start seeing results within a week of applying Termidor SC. Ants do not know they are coming in contact with the treated area so that is how it spreads throughout the colony.
Termidor SC is a great choice for termite treatments. It lasts 10+ years in the soil if applied as directed. I have included a termite article below for additional information on treating around your structure. If you are going to be treating the wood in the crawlspace, we recommend that you apply Bora-Care if treating for drywood termites.
If you have subterranean termites, you should perform a termite trenching treatment outside the structure and in the crawl space in accordance with our Subterranean Termite Treatment Guide with a non-repellent termiticide such as Termidor SC. Just spraying insecticide on the surface of the dirt will not help and is not an approved or appropriate use.
Termidor SC, when used as directed, is safe to use with people inside the home and you do not have to evacuate anyone from the premises. It should be perfectly safe for a pregnant woman since you will be treating outside.
While Termidor SC is a non repellent insecticide and most others are repellent, as long as you are thoroughly rinsing the sprayer between products it should be fine. We would recommend triple rinsing all parts of the sprayer before changing products.
Termidor SC may be used outdoors only for spider control, per the product label. We do have a great Spider Control Kit that includes CB-80 Aerosol Insecticide for contact spraying, and Temprid SC, which can be applied indoors as a crack and crevice or spot treatment. This kit also contains glue boards, which are excellent tools for monitoring and for catching stray spiders indoors. Please see our Spider Treatment Article for more information and tips about preventing spider infestations.
You can use Termidor SC for the listed pests twice a year at a rate of 0.8 oz (0.06% finished solution) per gallon of water or up to 4 times a year at a rate of 0.4 oz (0.03% finished solution) per gallon of water, sprayed 1 to 2 feet up the foundation and out on the ground.
