WOOD DESTROYING INSECTS - DRYWOOD TERMITES REMEDIAL CONTROL
- Do not apply this product in a way that will contact any other person. Only protected applicators may be in the area during application. Keep people or pets away from treated area until dry.
- In living areas, do not apply Optigard Flex Liquid as a broad¬cast spray. In these areas use only as a void application, or as a spot treatment (e.g., under and/or behind appliances) or crack-and-crevice application in areas where occupants will not be exposed to direct contact.
- When applying Optigard Flex Liquid as a crack-and-crevice or spot treatment in living areas, do not exceed 0.5 gallons/1,000 sq ft of a 0.1% finished dilution.
- For void applications, do not apply until location of heat pipes, ducts, water and sewer lines, and electrical conduits are known. Caution must be taken to avoid puncturing and injec¬tion into these structural elements. Do not apply into electrical switches or receptacles or other wiring where electrical shock hazards exist.
- DO NOT apply this product, by any application method, to linden, basswood, or Tilia species.
Optigard Flex Liquid must be applied as a diluted finished application using mixing directions contained in the label. Treatment techniques used should provide placement of the product in the infested areas or as near as possible. Optigard Flex Liquid may be applied to structural voids, in cracks, crevices, corners or other out-of-the-way places, such as under and behind kitchen appliances and baseboards, under sinks, around window and door frames, pipes and water heaters and in the attic, crawl space and garage. Acceptable locations for treatment also include non-living space areas including crawl spaces, attics and unfinished basements. Applications may be made as a crack-and-crevice spray, a coarse, low-pressure spot spray, a surface spray or as a structural void application. Application to structural voids such as wall voids may be done by drilling a small hole into the void area or using a self-puncturing tip and injecting diluted product so that surfaces inside the void area are treated. Existing holes created by construction features may also be used to gain access to void treatment areas.
As described in the section on Control of Pests in Voids, closed, in-wall delivery systems may be used to apply product to the surfaces inside void areas.
Optigard Flex Liquid may also be used as a banded, spot treatment or crack-and-crevice application to perimeter exterior areas of structures for control of listed pests.
For remedial control of wood-destroying insects including drywood termites, wood-destroying beetles, and carpenter bees, Optigard Flex Liquid may be used as a spot treatment, wood surface application, or void application.
WOOD DESTROYING INSECTS
Control of Drywood Termites
When used as specified in the label, Optigard Flex Liquid provides effective remedial control of localized intestations of drywood termites, including species of Incisitermes, Cryptotermes and Marginitermes. Knowledge of the biology and behavior of the drywood termite species involved, the locations and the extent of the infestation(s) will help to ensure successful control.
Treatment requirements for drywood termite control may vary due to state and local regulations. For advice concerning current drywood termite control regulations under local conditions, consult your State structural pest control regulatory agency.
Directions for Remedial Control of Drywood Termites in Infested Wood
To control drywood termites in localized areas of infested wood in structures, apply 0.1% Optigard Flex Liquid as a liquid or foam to voids and galleries in damaged wood, in spaces between wooden structural members or between wood and foundations. Locate galleries by using visual signs (e.g. fresh fecal pellets, or blistered wood), the presence of live pests, mechanical sounding techniques (tapping on the wood surface and listening for changes in sound to indicate changes in wood density), listening devices, motion detection devices or other technologies that help pinpoint drywood termite activity.
Wood Injection Method
Drill small diameter holes of appropriate size for the injection tip, or use a self-puncturing tip, positioned to intersect termite galleries within infested wood. Drywood termite emergence or pellet kick-out holes connect directly to galleries and are indicators of potential sites to drill and inject Optigard Flex Liquid. Care should be taken to avoid electrical wiring, plumbing, etc., when drilling and injecting. Do not drill or puncture completely through wood. Spacing of the holes will depend on the distribution of insect activity and galleries. Injection holes may be clustered in areas with insect activity as indicated by damage, live insects, or other indicators previously described. Injection holes on opposite sides of large (4”x10” or larger) structural beams may be necessary to effectively penetrate galleries.
Apply up to 50 ml. (1.7 fl. oz.) of finished Optigard Flex Liquid liquid solution at each injection hole. If using Optigard Flex Liquid as a foam preparation, inject a sufficient amount to fill galleries without allowing runoff.
Re-treatment guidelines: Reapply if insect activity within treated areas is detected 4 or more weeks following treatment. For best results in treating galleries, inject Optigard Flex Liquid into new injection holes positioned between previous injection sites.
Refer in the application diltion table for specific amount in fl oz or ml of Optigard Flex Liquid.
