Optigard Flex Liquid Insecticide

Product Overview

Breaking the boundaries of common pest control

Non-repellent chemistry with low use rates and flexible application methods to control pests both indoors and out.

Optigard® Flex, with the active ingredient thiamethoxam, is a non-repellent, liquid insecticide that is active against insects by both contact and ingestion and can be used both indoors and out.

Key Features

  • Non-repellent, versatile formulation goes where it’s needed – inside or outside, including food handling areas*, as a liquid or foam
  • Systemic activity by the active ingredient thiamethoxam in plants helps control honeydew-producing insects found in landscape environments that serve as food source for ant pests
  • Advanced non-repellent chemistry with low use rates that transfers throughout social insect colonies


*Newly approved EPA claim and may not yet be available on existing Optigard Flex product in the marketplace.  Applications must be made according to the label on the package you are using.

Key Benefits

  • Enables pest management professionals to make more targeted applications, using less active ingredient minimizing the amount of chemical used and saving PMP’s money
  • Thiamethoxam offers both contact and ingestion activity against a wide range of economically important pests such as ants, cockroaches and drywood termites, ensuring more complete control with fewer callbacks, 
  • Effective as a zone treatment, general surface spray, and crack and crevice application providing flexibility for technicians and reducing the number of products needed to complete a treatment

Increased control with systemic action

One of the most popular food sources for many ant species is honeydew, which is produced by homopterous insects such as scales, aphids and mealy bugs that feed on landscape vegetation. To control these insects, apply Optigard Flex to either the soil beneath plants or to the foliage of plants. These non-repellent products move through the plant systemically to help control homopterous pests.
