If a trench is needed, how deep does it need to be?
Termidor SC can only be applied to the top of the soil when you are using it as a perimeter pest control treatment against ants. If you are using Termidor SC to treat for active termites, or to protect your home against termites, you must apply the product into a trench. This is because termites do not walk across the ground like ants do, they live beneath the soil and enter your home below the grade level of the dirt. Therefore, you must place the Termidor SC into the ground to have a chance at them coming into contact with the product. Please read our informational article written for homeowners: "How To Do a Termite Treatment" which will tell you how deep to dig the trench and how to properly apply Termidor around your home.
