Optigard Flex is effective against a variety of ants and other nuisance pests. Application of Optigard Flex to void areas provides an additional point of treatment for nuisance pest problems. Application of Optigard Flex to structural voids is complemented by perimeter insecticide and bait applications. In addition to ants, Optigard Flex controls other nuisance pests, including beetles, crickets, boxelder bugs, ladybird beetles, earwigs, cockroaches, fire ants, etc. Control of these pests can be achieved by injecting 2–4 oz. of foam at multiple points in voids of target areas where ants or other pests are trailing into a structure, or in areas near plumbing penetrations in kitchens or bathrooms, where pests often seek food or moisture. Applications inside void areas should be directed at the lower six inches near the sill plate.

Optigard Flex has exhibited excellent non-repellent activity against drywood termites. Application of Optigard Flex for zone or spot treatments of drywood termites should focus on controlling active infestations. Optigard Flex may be applied with equipment suited for injection of foam into termite galleries in wood. Optigard Flex is compatible with a wide range of foam-generating equipment, including hand-pump or power models. Injections should be made by drilling into termite galleries and applying a foam preparation of Optigard Flex into each injection hole.

In addition to void applications, crack-and-crevice or spot applications may be made to control cockroaches in areas not easily accessible to humans. Treatment areas include points or cracks between different elements of construction, spaces between equipment and floor or wall, openings leading to voids in walls, spaces beneath equipment or cabinets, or spaces between trim and floors or walls. As a spot or crack-and-crevice treatment, apply 0.1% Optigard Flex dilution directly into cracks and crevices or other non-exposure areas as a low pressure spray using equipment capable of delivering a pin stream of insecticide.

Optigard Flex may be applied as a perimeter band around structures to control ants and other occasional insect pests. See label for specific application instructions.

In addition, Optigard Flex Liquid can also be applied to landscape ornamentals as a foliar spray or banded drench around the base of the plants to control honeydew producing insects and thus, the ants that feed on their honeydew secretions.

Always read and follow label directions carefully.
