Termidor SC (right) is a relatively new insecticide. The active ingredient in Termidor is fipronil; see the fipronil factsheet and Termidor label below. There are a number of active labels for fipronil-based insecticides currently sold in the US. Uses include flea medications, like Frontline and Frontline Plus, a commercial agricultural insecticide called Regent, and Termidor the structural pest control insecticide. Termidor SC (SC stands for soluble concentrate) is labeled for use against termites, in pre- and post-construction applications, carpenter ants as an exterior perimeter treatment and for nuisance ants (exterior only).

Termidor, or fipronil, is a slow-acting insecticide. This "delayed-action" effect allows insects like termites and ants, which live in colonies, time to carry some of the insecticide back to the nest where it contaminates the whole colony. This is why Termidor works well for carpenter ants as a foundation or perimeter spray because workers pick up the insecticide as they travel back and forth from the nest.

Perimeter treatments for carpenter ants can be done by many homeowners with the proper application and safety equipment. However, treatment for termites requires equipment and expertise beyond that available to most homeowners. If you need to hire pest control services for termites or carpenter ants see our suggestions here.

The smallest package size of Termidor SC is 20 oz. which makes 24 gallons of working solution at the lowest label rate. Termidor is available online and is not Restricted Use. A good quality 1 gallon sprayer will be needed to apply the working solution for perimeter treatments for carpenter ants.
