Termidor Insecticide

- A fipronil-based insecticide -

Summary: Termidor (tm) is a "new-generation", relatively low toxicity insecticide that is useful in a wide variety of pest control situations. Termidor contains the active ingredient fipronil and can be used for termites, carpenter ants, and nuisance ants outdoors.

Termidor treatment for termites and carpenter ants

Termidor (tm) is a relatively new insecticide with the active ingredient fipronil. There are a number of active labels for fipronil-based insecticides currently sold in the US including flea medications, a commercial agricultural insecticide called Regent, and of course Termidor for pests that damage structures like termites and carpenter ants.

Termidor SC (the 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). The smallest package size of Termidor SC is 20 oz (right) which makes 24 gallons of working solution at the lowest label rate. You will also need a good quality 1 gallon to apply the working solution for perimeter and spot treatments.

Termidor Insecticide has a "delayed effect"

Termidor is a slow-acting insecticide and this "delayed-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 and thus contaminate, and potentially kill, the whole colony.

While perimeter treatments for carpenter ants can be done by homeowners with the proper application and safety equipment (see specimen label for instructions, specimen and full pesticide labels are available from suppliers), Termidor treatments for termites generally require equipment and expertise beyond that available to most homeowners.

The pesticide label and the specimen label

A pesticide label is the official "instruction sheet" for the product and contains all of the information required for registration in the US, as well as instructions for its use. A specimen label is exactly the same as an official label except that a specimen label is not attached to an actual product container. Use specimen labels like the one below for general information only, always follow instructions that come with the product you are actually using.
