Termidor Insecticide

Termidor treatment for termites and carpenter ants

Termidor (tm) is a relatively new insecticide with the active ingredient fipronil; see the fipronil factsheet and specimen product label below. 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 garden-type sprayer to apply the working solution for perimeter and spot treatments.

While perimeter treatments for carpenter ants can be done by homeowners with the proper application and safety equipment (see specimen label below), treatments for termites generally require equipment and expertise beyond that available to most homeowners.

A specimen label (see Related Articles below) is the official product label that contains all of the information required for registration in the US and instructions for use of the insecticide. Use the label below for general information only, always follow instructions (the label) that come with the product you are actually using.
