(a) Subsections (b) - (f) of this section do not apply to baits or baiting systems and subsections (c) - (d) of this section do not apply to wood applied termiticide products.
(b) All pesticides used for pre-construction termite treatments must be registered with the Environmental Protection Agency and the department. All pesticide liquid applications must be made by using the application rates and methods and by following the precautionary statements on the labeling of the pesticide being used.
(c) For a full treatment, the entire structure must be treated to provide a continuous horizontal and vertical pesticide barrier. The final treatment shall be performed within thirty (30) days of notification of completion of landscaping or one (1) year from the date of completion of construction, whichever comes first. However, when construction has proceeded to the point that all areas cannot be treated before the company providing the treatment is called to perform the application, a partial treatment is permitted if the owner of the structure or the person in charge of the construction and the licensee for the pest control company sign a statement attesting to the construction conditions, and attach it to the contract with an amended diagram or blueprint or building plat showing the exact areas to be treated and send copies to the owner of the property within seven (7) days of the application. A copy of the disclosure with an amended diagram or blueprint or building plat showing the exact areas to be treated must be made available to the department upon request. A partial treatment will also be permitted if allowed by label directions and if the licensee proposing the treatment issues a Wood Destroying Insect Treatment Disclosure Document prior to the treatment.
(d) In order to comply with subsection (c) of this section, it will be necessary to return to the pretreatment site after the slab has been poured and/or piers and support beams have been placed to complete the treatment for the vertical barrier.
(e) A primary treatment of the wood framing (such as a borate treatment) must follow full label application instructions and must be performed with a termiticide that has specific label instructions to be used as a primary treatment to offer protection for prevention of subterranean termites in new construction. This treatment may be used in lieu of a full, partial, or bait treatment and must include application instructions to exposed surfaces of wood framing with exterior sheathing in place but before any walls are enclosed to a height of not less than two (2) feet above a contact with a slab foundation or a (2) foot horizontal and vertical treatment of wood above contact with a concrete crawlspace or basement foundation. Label instructions must provide application instructions for the prevention of subterranean termite intrusion and tubing onto non-cellulose areas around bath-traps, plumbing penetrations, and concrete foundation areas.
(f) Notice of all pre-construction treatments with contracts requiring treatment of a structure other than a single family dwelling must be submitted between the hours of 6:00 a.m. and 9:00 p.m. using the department's designated notification system at least four (4), and no more than twenty-four (24) hours prior to a termiticide application. The licensee must provide address and site location, type of treatment (partial or full), date and time of treatment, approximate and appropriate unit of measurement used under contract, and the name, license number, and physical address of the pest control business. If the treatment is cancelled, notice of cancellation must be sent using the department's designated notification system within one (1) hour of the time the pest control business learns of the cancellation.
(g) For all commercial pre-construction treatments other than baits, baiting systems, wood applied termiticide products or physical barriers, the licensee must maintain records of the appropriate unit of measurement treated per application site, amount of termiticide used per application site, rate at which termiticide is mixed for each application site, number of application tanks which were in use for the treatment, the capacity, in gallons, of each application tank, and the start and stop time for the treatment. The business license holder or, in the case of the certified noncommercial applicator, the applicator must keep and maintain a correct and accurate copy of the pre-construction treatment and disclosure records for a period of two (2) years. A baiting system may be used in lieu of a pre-construction treatment if installed within thirty (30) days of notification of completion of landscaping. All termite baiting system applications must be made using the methods and following the precautionary statements on the product label. If a physical barrier is used, the appropriate unit of measurement of the physical barrier must be recorded and a diagram describing the installation must be provided.
