How To

Optigard Flex as a liquid: Use liquid applicators (compressed air sprayers, backpack, or power sprayers). Follow label directions for desired concentration. For Ants and Other Nuisance Pests: Outdoors as a general liquid spray to trails, spot treatment to pest entry points or as a perimeter foundation spray. Use indoors as a crack-and-crevice application. For Wood-Destroying Insects: Apply sufficient product to treat termite galleries and infested areas.

Optigard Flex as a foam preparation: Use foam generating applicators. Mix into tank 0.1% finished foam concentration and see label for mixing instructions. For Ants and Other Nuisance Pests: Outdoors - apply spots of 2-4 oz finished foam at pest entry points to the structure. Void application, applied from indoors or outdoors. For Wood-Destroying Insects: Application to drywood termite galleries.

Optigard Flex may be applied to landscape ornamentals to control honeydew-producing insects and thus, the ants that feed on their honeydew secretions. Use a 0.1% liquid dilution of Optigard Flex as a foliar or banded application and apply up to 2 gallons per 1,000 feet2. Retreat as necessary to maintain control.
