PRE-CONSTRUCTION TREATMENT - TREATMENT AROUND WELLS AND CISTERNS
CONTROL – GENERAL
Treatment standards for subterranean termite control may vary due to regulations, treatment procedures, soil types, construction practices and other factors. The purpose of chemical soil treatment for termite control is to establish a continuous chemical treated zone (horizontal and/or vertical as needed) between the wood and other cellulose material in the structure and the termite colonies in the soil. Follow all federal, state, and local regulations and treatment standards for protection of a structure from termites. In some instances where an aerial or above ground colony is established, supplemental treatments to control the termites, landscape modifications, and/or structural repairs may be needed to deprive termites of a moisture source. Use a 0.05% dilution based on local recommendations. Generally a 0.05% dilution is used for typical control situations.
Do not apply at a lower dosage and/or concentration than specified on the label for application prior to installation of the finished grade. Prior to each application, applicators must notify the general contractor, construction superintendent, or similar responsible party, of the intended termiticide application and intended sites of application and instruct the responsible person to notify construction workers and other individuals to leave the area to be treated during application and until the termiticide is absorbed into the soil.
Retreatment for subterranean termites can only be performed if there is clear evidence of reinfestation or disruption of the treated zone due to construction, excavation, or landscaping and/or evidence of the breakdown of the termiticide treated zone in the soil.
Please refer to the label for further information regarding retreatment.
GENERAL PRECAUTIONS FOR APPLICATIONS
Do not plant for the purpose of consumption, edible plants into the treated areas of soil.
Avoid contamination of public and private water supplies. Use anti-backflow equipment or an air gap on filling hoses.
Consult State, Federal, or local authorities for information regarding the approved treatment practices for areas in close proximity to potable water supplies.
TREATMENT AROUND WELLS AND CISTERNS
Do not contaminate wells or cisterns.
Structures With Wells/Cisterns Inside Foundations: Structures that contain wells or cisterns within the foundation of a structure can only be treated using the following techniques:
1. Do not apply within 5 feet of any well or cistern by rodding and/or trenching or by the backfill method. Treat soil between 5 and 10 feet from the well or cistern by the backfill method only. Treatment of soil adjacent to water pipes within 3 feet of grade should only be done by the backfill method.
a. Trench and remove soil to be treated onto heavy plastic sheeting or similar material or into a wheelbarrow.
b. Treat the soil at the rate of 4 gallons of solution per 10 linear feet per foot of depth of the trench, or 1 gallon per 1.0 cubic feet of soil. Mix thoroughly into the soil taking care to contain the liquid and prevent runoff or spillage.
c. After the treated soil has absorbed the solution, replace the soil into the trench.
Structures With Adjacent Wells/Cisterns and/or Other Water Bodies: Applicators must inspect all structures with nearby water sources such as wells, cisterns, surface ponds, streams, and other bodies of water and evaluate, at a minimum, the treatment recommendations listed below prior to making an application.
1. Prior to treatment, if feasible, expose the water pipe(s) coming from the well to the structure, if the pipe(s) enter the structure within 3 feet of grade.
2. Prior to treatment applicators are advised to take precautions to limit the risk of applying the termiticide into subsurface drains that could empty into any bodies of water. These precautions include evaluating whether application of the termiticide to the top of the footer may result in contamination of the subsurface drain. Factors such as depth to the drain system and soil type and degree of compaction should be taken into account in determining the depth of treatment.
3. When appropriate (i.e., on the water side of the structure), the treated backfill technique (described above) can also be used to minimize offsite movement of the termiticide.
Amount of product to be used at specific gallonage of water in order to make 0.05% dilution:
- 0.3 fl oz/gallon of water
- 6.9 fl oz/25 gallons of water
- 13.8 fl oz/50 gallons of water
- 27.5 fl oz/100 gallons of water
It is recommended that application volumes described in the PREMISE Pre-Construction Insecticide “DIRECTIONS FOR USE” be used whenever possible. However, where soil conditions will not accept application of 4 gallons of PREMISE Pre-Construction Insecticide per 10 linear feet, twice the PREMISE Pre-Construction Insecticide concentration may be applied in 2 gallons of solution per 10 linear feet. For example, if 0.05% is the correct use rate to be applied in 4 gallons of water, then 2 gallons of 0.1% dilution may be used per 10 linear feet to deliver an equivalent amount of PREMISE Pre-Construction Insecticide per unit of soil.
