CONTROL OF PESTS IN VOIDS - ANTS (EXCEPT CARPENTER AND PHARAOH), ETC.

General Information

USE RESTRICTIONS

- 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.

APPLICATION PROCEDURES

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.

Limitations, Restrictions, and Exceptions

CONTROL OF PEST IN VOIDS

Arthropod pests may occasionally invade structures through wall voids or other structural voids by entering cracks or other openings to the exterior. In conjunction with other appropriate methods such as exclusion or perimeter insecticide applications, Optigard Flex Liquid can control nuisance arthropods that move through or harbor in wall void areas. For best results, use Optigard Flex Liquid as part of an Integrated Pest Management (IPM) approach, in conjunction with other appropriate control methods such as perimeter insecticide applications, use of baits and the use of exclusion or other non-chemical control methods.

Method of Injection into Voids

To control listed pests, apply Optigard Flex Liquid at 0.05%-0.1% finished solution/foam to surfaces inside structural voids. Application to structural voids such as wall voids should be done by drilling a small hole into the void area, or using a self-puncturing tip, and injecting product as liquid or foam so that wood surfaces inside the void area are treated. Existing openings such as those around door or window frames may also be used as entry points to inject product. Apply enough volume to lightly coat the target surface. Do not exceed liquid volume that would allow runoff (e.g. for wood, runoff is about 0.05-0.1 ml./sq. inch). For example, a 2”x4”x16” wall void with wood frame should be treated with 2-4 ml. finished liquid solution per linear foot; other surfaces or wall void sizes may need more or less to achieve a light coating. For foam preparations, see instructions for use provided in the MIXING PROCEDURES section of the label. Apply approximately 60 – 120 ml. (2 – 4 fl. oz.) finished foam preparation per application point. Alternatively, closed, in-wall delivery systems may be used as described below to apply product to the surfaces inside void areas.

For optimal results, use foam application.

Remarks

Use 0.1% rate for heavy pest infestations.

Optigard Flex Liquid may be used as a liquid or foam treatment to control ants (except carpenter ants and Pharaoh ants) in termite monitoring stations.

Ant (except carpenter ant and Pharaoh ant) mounds may also be spot treated with 0.05 – 0.1% finished liquid or foam.

FIXED IN-WALL DELIVERY SYSTEMS

Closed, in-wall insecticidal delivery systems such as perma¬nently installed piping or flexible tubing may also be used to deliver diluted product to inaccessible areas. Generally, about one ounce of finished liquid product is needed per 35-40 ft of tubing (based on 1/8”-diameter tubes). For these systems, use 0.05%-0.1% dilution rates as listed in the Application Dilution Table. Prepare the finished product at the appropri¬ate dilution, inject into system as recommended by delivery system manufacturer.
