Compilation of Rules and Regulations of the State of Georgia › Department 620 - RULES OF GEORGIA STRUCTURAL PEST CONTROL COMMISSION › Chapter 620-6 - WOOD DESTROYING ORGANISMS › Rule 620-6-.04 - Control Measures

Current through Rules and Regulations filed through June 27, 2024
"Control Measures" means the application of any and all
				measures for the purpose of controlling termites, powder post beetles, wood
				boring beetles, wood destroying fungi, and any other wood destroying organism
				in structures and/or adjacent outside areas. Such measures shall be made with
				applications and installations consistent with label requirements. Minimum
				adequate control measures shall be as set forth below.
(1) Minimum adequate subterranean termite
			 control treatment for post construction shall include the following:
(a) For pesticide products applied as a
			 comprehensive soil termiticide application consistent with registered label
			 directions:
1. Removal of all cellulosic
			 material from underneath the building and removal of any other debris which
			 would interfere with inspection or treatment in such area.
2. Removal of all wooden contacts between
			 buildings and outside soil, other than those wooden supports which have been
			 treated with preservatives to a minimum preservative retention designed for
			 ground contact. The top of all supports for untreated wooden members shall be
			 no closer than six (6) inches to the soil. In no case shall the minimum
			 clearance between untreated wood and soil be less than six (6) inches. This
			 requirement shall apply only to those situations where wood is exposed and by
			 design is not separated from the outside soil line by anything other than air
			 space. Such clearance shall not apply to sill plates or other wooden members of
			 a structure which may be physically closer to the earth than the required
			 clearance but are by design enclosed by and insulated from the earth by brick,
			 stucco or other construction material.
3. Removal of all wooden contacts between
			 buildings and inside soil, other than those wooden supports which have been
			 treated with preservatives to a minimum preservative retention designed for
			 ground contact. In no case shall the minimum clearance between wood and soil in
			 a crawl space be less than eighteen (18) inches.
4. Removal of all visible accessible termite
			 tunnels.
5. Trenching of soil
			 along the outside and inside of foundation walls and around pillars and other
			 supports to a minimum depth of six (6) inches, but not lower than the top of
			 the footing in contact with the soil. Rodding may be performed from the bottom
			 of the trench to lower depths as required. When the top of any footing is
			 exposed and not in contact with the soil, trenching should not extend below the
			 bottom of the footing.
6.
			 Application of approved termiticide.
(i)
			 Approved termiticides shall be those registered by the United States
			 Environmental Protection Agency (EPA) and the Georgia Department of
			 Agriculture. Under no circumstances shall the concentration applied be lower
			 than the minimum nor greater than the maximum concentration specified on the
			 product label for the termiticide as a soil termiticide application.
(ii) Rate of application shall be four (4)
			 gallons per ten (10) linear feet per foot of depth from the soil surface to the
			 lesser of either the top of footings or a depth of four (4) feet applied to the
			 trenches and backfill. Soil into which pipes extend from the structure, soil
			 under expansion joints, and soil in any other critical point of potential
			 termite entry must also be treated with the approved termiticide at the above
			 application rate.
(iii) Measures
			 must be taken to prevent the back siphoning of pesticides and the contamination
			 of public water supplies during dilution and filling operations. Do not apply
			 pesticide while precipitation is occurring in any area where the application
			 would be impacted by the precipitation.
(iv) Precautions must be taken to prevent the
			 contamination of wells or cisterns, in or close to the structure being treated.
7. Drilling of all
			 tile, brick, concrete block or other type cavity walls, chimneys, hollow
			 pillars or other similar structure parts and application of the approved
			 termiticide at a rate of two (2) gallons per ten (10) linear feet. Drilling of
			 concrete blocks or other hollow masonry parts shall be made into the large
			 voids only, as opposed to the vertical mortar joints, at horizontal intervals
			 of no more than twelve (12) inches. Application of the termiticide shall be
			 made through drill holes no more than eighteen (18) inches above the lowest of
			 the soil or slab surfaces contiguous to the opposite side of the vertical wall.
			 In the case of uncapped hollow parts, the termiticide may be applied through
			 the top opening, provided the termiticide is released no higher than eighteen
			 (18) inches above the top of the footing.
8. Treatment of the entire inside perimeter
			 walls of all earth filled porches beneath concrete slabs contiguous to the
			 structure with an approved termiticide at the rate of four (4) gallons per ten
			 (10) linear feet by one of the following:
(i)
			 Making access openings, by removing a six (6) inch band of soil along the
			 entire inside perimeter walls and applying the termiticide in the
			 trench.
(ii) Drilling from the top
			 of the entire perimeter of the slab at intervals of no more than twelve (12)
			 inches and no more than twelve (12) inches from the perimeter wall and applying
			 the termiticide.
(iii) Drilling,
			 rodding, and applying the approved termiticide from the inside of the
			 foundation at no more than twelve (12) inch intervals along the entire inside
			 perimeter and as close as possible to the lower edge of the slab.
(iv) Drilling, rodding, and applying the
			 approved termiticide from the sides of the earth fill along the entire
			 perimeter provided no horizontal rodding distance shall exceed twenty (20)
			 feet.
9. Treatment of
			 all grade level slabs contiguous to the structure with an approved termiticide
			 at the rate of four (4) gallons per ten (10) linear feet by drilling and
			 applying along the entire distance where slab joins any part of structure at
			 intervals of no more than twelve (12) inches and no more than twelve (12)
			 inches from the structure wall.
10. Treatment of all structures with concrete
			 slabs at or above grade level with an approved termiticide at the rate of four
			 (4) gallons per ten (10) linear feet by one of the following:
(i) Treating from the inside by drilling
			 through from the top of the slab and applying the approved termiticide at
			 intervals of no more than twelve (12) inches and no more than twelve (12)
			 inches from the outside edge of slab along the entire perimeter and at all
			 other points of potential termite entry through the slab. After such
			 application all holes shall be securely sealed to prevent any upward movement
			 of the termiticide.
(ii) Treating
			 from the outside by rodding and applying termiticide along and under the entire
			 perimeter of the slab by inserting the rod as close as possible to the lower
			 edge of the slab.
11.
			 Treatment of monolithic slabs by trenching and application of the approved
			 termiticide to the soil along the entire perimeter of the slab at the rate of
			 four (4) gallons per ten (10) linear feet and to any openings through the slab.
