Termite Pre-treatment
"Pre-treatment" is a term for termiticide that is applied to the soil. This page relates principally to the continental United States as other parts of the world (including Hawaii) often have less toxic approaches to termite management. It refers to the use of toxins applied to the soil as a means of blocking concealed access to a structure by subterranean termites (as opposed to drywood termites).
Most new structures in United States are treated against termites during the initial construction process. These applications of poisons into the soil under and around building being constructed are what is meant by "termite treatments" and in the trade these are commonly referred to as pre-treatments or “pre-treats.” Physical barriers and proper construction are other methods of preventing termite infestation.
A termite pre-treat is intended to create a barrier of termiticide between termites found in the soil and wooden structures of the building. To provide a consistent barrier, termiticide labels (the registered labels applied to the retail containers) recommend the volume, concentration and areas for the application of the termiticide. In effect, large volumes of emulsion are needed to effectively fill the soil around the foundation walls, support piers and the soil to be covered with concrete slabs. It is a violation of US Federal Pesticide Laws and most State laws to apply termiticides at concentrations and/or volumes less than indicated rate prescribed by the brand label, however, others following the US FIFRA Act allow for a lower dosage to be applied where the applicator considers this appropriate.
The cost of termite pre-treatments have risen significantly over the last decade due to a move towards newer, more complex chemicals and the costs of labor, insurance, and fuel. Treating a 140 sq m (1,500 sq ft) home can cost US$200 to US$600 in chemical costs alone. Cost can also differ depending on the type of construction materials, soil compaction and foundation.
