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 can only be applied outside around the foundation 1 to 2 feet up and out for general pest control but you would not treat on porous surfaces such as a driveway.. We do have a guide here that can help for getting rid of millipedes. For areas further out in the yard and around the perimeter edges of the driveway you can use something like Talstar P.
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.
Termidor SC cannot be applied on the grass in the lawn for treating any insects including fire ants. It is labeled for applications up against the structure for other ant species and crawling insects as well as in the soil for termite applications. It is not labeled for treating fire ants. We do carry products that can be applied for control of fire ants. Please take a few moments to review our article on How to Get Rid of Fire Ants for more details.
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.
