Controlling Termites With Termicide Treatments



CONTROLLING TERMITES WITH TERMITICIDE TREATMENT


PART 1---GENERAL

1.01 SUMMARY

    A.   This procedure includes guidance on treating wood
         construction to control termites by injecting infested
         areas with termiticide.

    B.   Termites, beetles, and carpenter ants cause less visible,
         but more serious problems than more visible insects.

    C.   Termites are wood eating insects which attack primarily
         soft sapwood. They are most active in locations with high
         moisture and usually enter the wood at or below ground
         level.  Beetles also eat wood, even in dry areas above
         ground.  Carpenter ants burrow into wood to make a home,
         not to find food; they seldom are a serious problem.  

    D.   See 01100-07-S for general project guidelines to be
         reviewed along with this procedure.  These guidelines
         cover the following sections:

         1.   Safety Precautions

         2.   Historic Structures Precautions

         3.   Submittals

         4.   Quality Assurance

         5.   Delivery, Storage and Handling

         6.   Project/Site Conditions

         7.   Sequencing and Scheduling

         8.   General Protection (Surface and Surrounding)

         These guidelines should be reviewed before performing
         this procedure and should be followed, when applicable,
         along with recommendations from the Regional Historic
         Preservation Officer (RHPO).

1.02 SUBMITTALS

    A.   Product Data:  Submit manufacturer's technical data and
         application instructions to RHPO for approval before
         proceeding with treatment operations.

1.03 QUALITY ASSURANCE

    A.   In addition to requirements of these specifications,
         comply with manufacturer's instructions and
         recommendations for work, including preparation of
         substrate and application.

    B.   Engage a professional pest control operator, licensed in
         accordance with regulations of governing authorities for
         application of treatment solution.

    C.   Use only termiticides which bear a Federal registration
         number of the U.S. Environment Protection Agency.

1.04 PROJECT/SITE CONDITIONS

    A.   Restrictions:  Do not apply treatment solution except as
         otherwise required in construction operations.  Apply in
         an industry standard manner such that contamination by
         toxic or hazardous chemicals does not occur in any
         adjacent or occupied areas.

1.05 WARRANTY

    A.   Furnish written warranty certifying that applied
         termiticide treatment will prevent infestation of
         termites and, that if termite activity is discovered
         during warranty period, Contractor will retreat building
         and repair or replace damage caused by termite
         infestation.

         1.   Provide warranty for a period of 5 years from date
              of treatment, signed by Applicator and Contractor.


PART 2---PRODUCTS

2.01 MANUFACTURERS

    A.   PRG, Inc. (Preservation Resource Group)
         P.O. Box 1768
         Rockville, MD  20849
         301/309-2222

2.02 MATERIALS

    A.   Emulsible concentrate termiticide for dilution with
         water, specially formulated to prevent infestation by
         termites such as "Bora-Care" (PRG, Inc.), or approved
         equal.  
         1.   A high-concentration solution containing the active
              ingredient disodium octaborate tetrahydrate
              formulated in a specially patented carrier system.

         2.   Provides a high-degree of repellency and rapid
              elimination of active infestation in a single
              application.

         3.   EPA registered for preventive and remedial
              treatments; odorless; colorless; long lasting.

         4.   Penetrates the wood, eliminates active infestations
              and provide long-term protection against future
              infestations.

         NOTE:  Other solutions or methods of application may be
         used as recommended by manufacturer or applicator if also
         acceptable to the RHPO and approved for intended
         application by jurisdictional authorities.

2.03 EQUIPMENT

    A.   Spray equipment for application of termiticide
         concentrate as recommended by termiticide manufacturer.


PART 3---EXECUTION

3.01 EXAMINATION

    A.   Inspect all wood portions of a building for insect damage
         at least once each year.  Look for signs of insect
         activity, such as:

         1.   Clay tubes on pieces of wood

         2.   Small holes in the wood

         3.   Small unexplained piles of sawdust

    B.   If any of these signs appear between inspections, an
         insect control specialist should be called in to make a
         thorough investigation.

3.02 PREPARATION

    A.   Remove foreign matter which could decrease effectiveness
         of treatment on areas to be treated.

3.03 ERECTION, INSTALLATION AND APPLICATION

    NOTE:  TERMITICIDE TREATMENT WILL NOT STRENGTHEN DETERIORATED
    WOOD. STRUCTURAL MEMBERS THAT ARE NO LONGER SOUND MUST BE
    REPAIRED OR REPLACED.  

    A.   For Spot Treatment of Infested Areas:

         1.   Dilute termiticide concentrate with water according
              to manufacturer's instructions.

              NOTE:  FUEL OIL IS NOT PERMITTED AS A DILUENT.  

         2.   Saturate the infested and surrounding area with
              diluted termiticide using a spray.  Apply at rate
              recommended by manufacturer.

              NOTE:  BE SURE TO TREAT THE ENTIRE INFESTED MEMBER
              TO ENSURE THAT THE ACTIVE INGREDIENT IN THE
              CONCENTRATE REMAINS AT A LEVEL HIGH ENOUGH FOR
              EFFECTIVE CONTROL.  WOOD THAT HAS NOT BEE TREATED
              WILL NOT BE PROTECTED.

    B.   Post signs in areas of application to warn workers that
         termiticide treatment has been applied.  Remove signs
         when areas are covered by other construction.

    C.   Reapply treatment solution to areas disturbed by
         subsequent construction activities following application.
