    (Specifier Note: The purpose of this guide specification is to assist the Specifier in correctly specifying termite control and its application or installation. The Specifier needs to edit these guide specifications to fit the needs of each specific project. Contact a Nisus Corporation representative to assist in appropriate product selections. Throughout the guide specification, there are “Specifier Notes” to assist in the editing of the file. Brackets [ ] have been used to indicate when a selection is required.

    References have been made within the text of the specification to MasterFormat 2004 Section numbers and titles. The Specifier needs to coordinate these numbers and titles with sections included for the specific project.

    This guide is for commercial applications using a termiticide and physical barrier termite system to protect structures from subterranean and Formosan termites.

     ?Bora-Care Commercial Termiticide is a “green” mineral-derived borate-based EPA-registered

    product applied directly to the structure of a building as a primary termite barrier. It uses a patented glycol solution to create a continuous barrier of protection on concrete, masonry, metal/steel, wood, pipe penetrations, bath traps and other subterranean termite entry points. ? Bora-CareCommercial is applied as a continuous horizontal and vertical application in a minimum two-foot band to all structural wood, foundations, bath traps, and/or pipe protrusions. It provides the highest level of active ingredient against termites and is the only borate-based termiticide with product-specific long-term efficacy studies and application history against ?subterranean termites. Bora-Care Commercial should not be used below-ground, or where

    treated exterior surfaces are not protected from weather, in direct contact with the ground or in continuous contact with water.

    Termistops are a non-chemical, physical termite barrier made of high grade stainless steel mesh, available in a range of sizes, designed to be fitted to plumbing and other service penetrations before the concrete slab is poured. When clamped to each individual penetration, the concrete “keys” into the mesh eliminating the small gap between the concrete slab and

    service pipe that would allow entry by termites. Termistops alone address only single pipe penetrations and should therefore be used in conjunction with a Bora-Care Commercial termite treatment to provide protection to all potential termite entry points.
