PRE-CONSTRUCTION TREATMENT - CRAWL SPACES
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.
Application must be made by trenching or trenching and rodding downward along the inside and outside of foundation walls, around piers, interior supports in contact with soil, plumbing, and utility services. Apply 4 gallons of solution (see APPLICATION VOLUME) per 10 linear feet, per foot of depth to provide a uniform treated zone. Rodding may be done from the bottom of a shallow trench to top of the footing or a minimum of 4 feet. When rodding, rod holes must be spaced in a manner that will allow for a continuous chemical treated zone to be deposited along the treated area. Rod holes should not extend below the footing. When trenching, the trench should be about 6 inches wide and 6 inches deep. Use a low pressure spray to treat soil which will be placed in the trench, mixing the spray solution with soil as it is being placed in the trench.
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.
