Minimum Specifications for Termite Control Work
(Note: An updated minimum specifications should be sought because standards can change.)
D. Treatment of Existing Slab-type Construction
1. Ground Treatment
a. Trench around the entire perimeter of the structure being treated, adjacent to the foundation wall.
b. All trenches must be approximately 4 inches wide at the top, angled toward the foundation and sufficiently deep (approximately 6 inches) to permit application of the required chemical. Apply the emulsion into the trench at a rate and manner prescribed on the label. Rodding will be acceptable where trenching will damage flowers and shrubs. Maximum distance between rod holds shall be 4 inches.
2. Bath Traps
a. An access hole a minimum of 6 inches x 8 inches shall be provided to all bathtub plumbing. Specifications must have a waiver of the listed item or items signed by the owner before the treatment. A copy of the signed waiver must be filed with the Louisiana Department of Agriculture and Forestry with the monthly Termite Eradication Report.
b. If the soil in a trap does not reach the bottom of the slab, the trap must be filled to within 2 inches of the top of the slab with soil before treatment. Treat bath traps as required by label.
c. A tar-filled bath trap must be drilled and treated as required by label.
d. If bath trap is a solid concrete pour, it must be drilled and treated as close as practical to the bathtub plumbing.
3. Other Openings in Slab
a. All showers must be drilled and treated as close as practical to shower plumbing.
b. Rod under or drill through the slab, and treat all areas beneath expansion joints and cracks in the slab according to label instructions. When the slab is drilled, the holes must be no more than 24 inches apart along the above stated areas.
c. All other openings (plumbing, etc.) must be treated as required by labeling.
E. Pre-treatment of Slabs
1. Treat as required by labeling.
2. Within 12 months after initial treatment, the outside of the foundation wall will be trenched and treated as required by label. Rodding will be acceptable where trenching may damage flowers or shrubs. Maximum distance between rod holes shall be 4 inches.
