Approved Pesticides; Minimum Requirements
Section 2-1-3-11-01-118.02 - Treatment Requirements Subterranean Termites Pier Type (Crawl Space) Construction

1. Remove all cellulose bearing debris such as scrap wood, wood chips, paper, stumps, dead roots, etc., from underneath buildings. Large stumps or roots that are too sound to be removed may be trenched, drilled or rodded and treated provided they are six inches or more from foundation timbers.

2. Remove all wooden contacts between building and soil, both inside and outside. Wooden supports under buildings must rest on a concrete footing, a brick capped with concrete, or other non cellulose materials. The top of the brick or footing should not be less than six inches above the ground. This includes but is not limited to wood steps, skirting and lattice work, form boards, piers and stiff legs. (Pressure treated piling foundations are exempt from this requirement.)

3. Termite tunnels Scrape off all termite tunnels from foundation walls and pillars.

4. Trenches Cut trenches a minimum of four inches wide and deep, but not below top of footing, in contact with masonry around all exterior and interior foundation walls and pillars and apply pesticide according to label directions. Soil injection techniques will be accepted by the Bureau when they are used in accordance with label directions.

5. Pipes Pipes underneath the structure should be treated by rodding or trenching according to label directions. All non metal packing around pipes should be saturated with an approved pesticide.

6. Treatment of Masonry and Voids Approved pesticides shall be applied to porous areas, cracks and voids in foundation walls, piers, chimneys, step buttresses and other structures likely to be penetrated by termites. (1) Flood all cracks in concrete. (2) Drill mortar joints on all two course brick formations such as piers, foundation walls, chimneys, step buttresses, etc., in a horizontal line at sufficient intervals to provide thorough saturation of wall voids but in no case shall the distance between holes exceed 24 inches. Holes shall be deep enough to reach the center mortar joint and shall be flooded under sufficient pressure to flood all cracks and voids therein. Drilling shall not be required when solid concrete footing extends above grade level or when wall is capped with solid concrete. (3) Drill mortar joints on all brick formations with three or more courses of brick on each side of formation at the end of every other brick but with the locations of the holes on each side of the formation alternating as much as is practicable and flood under pressure all cracks and voids therein. Where the outside finish of a three course brick wall makes drilling from each side of wall impractical, this wall can be drilled from one side by extending holes two bricks deep. (4) Drill into the center of each vertical core in a complete row of hollow concrete (or other light weight aggregate) blocks in construction using this type of building material and apply an approved pesticide into the openings. In hollow concrete block construction, drilling will not be required where accessibility to the opening is already available through construction.

7. Dirt Fills All dirt filled structures such as concrete slab porches, steps, chimneys, porch columns, etc., shall be treated by excavating, trenching, and applying pesticides in the same manner as around pillars and foundations. EXCEPTION: If due to construction, it is impractical to break into and excavate dirt filled areas, a method acceptable to the Bureau such as drilling, flooding or rodding may be employed.

8. Beetles Approved controls must be applied in accordance with subsections 119.01, 119.02 and 119.03 of these regulations for beetles in timbers, walls and flooring, if beetles are present, unless contract states that protection against beetle injury is not included.
