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.
Your treatment should not be done within 24 to 48 hours of any rainfall for the best results. Your trench should be 6'' wide, 6'' deep and 10 linear feet along the structure with the Termidor. You can take a look at our site on How to Do a Termite Treatment to give you the proper application instructions for the best results.
Termidor SC is not labeled to eradicate house flies as it should be applied in the soil for a termite treatment and only on the exterior surface (1ft up and 1 ft out) directly up against the foundation for insects that crawl on top of the soil. For more information on treating house flies, please read the article below. Please let us know if you need anything else.
Termidor SC is not labeled for grubs but we do offer products that are effective. Please take a few moments to review our article on How to Get Rid of Grubs for the best results.
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 is best applied in the trench as this is the most continuous application method. There are places all over the BASF Termidor product label, which clearly state that rodding alone is not sufficient, no matter what applicator tool used, to treat a home for termites. You can either do a 6x6 trench around the foundation, or a 6x6 trench with rodding used additionally every 12 inches through the trench at a depth not to exceed the footing of the home. If you just cannot trench the area you may also consider the bait stations as an alternative. You can also refer to our How To Do A Termite Treatment article for treating your home yourself.
Yes, you can apply Termidor to drilled holes in your basement. You would drill along the inside perimeter 12 in apart. Be sure to apply 4 gallons mixed solution per 10 linear feet. The only permissible ways Termidor can be used indoors is when it is applied to drilled holes or wall voids.
