PRE-CONSTRUCTION TREATMENT - HOLLOW BLOCK FOUNDATION OR VOIDS
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.
HOLLOW BLOCK FOUNDATIONS OR VOIDS
Hollow block foundations or voids in masonry resting on the footing may be treated to provide a continuous chemical treated zone in the voids at the footing. Apply 2 gallons of solution per 10 linear feet to the lower part of the void so that it reaches the top of the footing or soil. Treatment of voids in block or rubble foundation walls must be closely examined. Applicators must inspect areas of possible runoff as a precaution against application leakage in the treated areas. Some areas may not be treatable or may require mechanical alteration prior to treatment. All leaks resulting in the deposition of termiticide in locations other than those prescribed on the label must be cleaned up prior to leaving the application site (refer to Precautionary Statements). Do not allow people or pets to contact or reoccupy the contaminated areas of the structure until the clean up is completed.
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.
