Termidor SC is applied as a spray once every six weeks topically up against the foundation for insects that crawl on top of the soil, such as ants. If you are trying to treat for subterranean termites, you will want to dig a trench up against the structure, and if there is concrete up against the foundation you will need to drill to apply the product. Please take a few moments to review our article on How to Get Rid of Subterranean Termites for specific application instructions.
