Pretreatment is a kind of termite control that is executed by having the termite prevention company come in before construction of a building is finished, so that the termite exterminators may pretreat the area around and under the building with pesticides that shall prevent termites from infesting or even invading the area. It works particularly well when combined with other early termite control methods, such as the use of termiticide-treated wood for construction or the elevation of wooden areas from the ground. In the United States, there are at least three kinds of termite pretreatments that are widely available, and they are listed and described below.

  1. Pretreatment of the Crawlspace – this type of pretreatment is for those buildings that have suspended floors. Often but not always, when suspended flooring is built, the gap between the suspended floor and the actual ground is usually large enough to be called a crawlspace, or an area through which a person may crawl. With this type of pretreatment, the termiticide is applied here, to the foundations of that space, which then serves as the location of the anti-termite poison barrier. This is perhaps one of the less precise forms of pretreatment, and certainly the second method in this list is usually far more often used, not least because it is perfect for most US homes.
  2. Pretreatment of the Basement Area – the foundations of the basement are critical places for termite control specialists, hence part of the popularity of this particular type of pretreatment. The other main factor contributing to this method’s popularity would be the popularity of another thing: the hollow-block basement. Hollow blocks are wonderful building materials that do not cost much and are also very easy to layer on, but they are also highly susceptible to termite infestations and attacks from the surrounding soil, most especially because their hollows create such excellent spaces for termites to use. As such, this type of pretreatment attempts to reduce the problem by creating a chemical shield around the foundations in order to keep termites from getting in. To be sure, the shield cannot be a perfect: in most occasions, a few gaps and spaces shall still exist. But if done thoroughly and by a very good technician, this should significantly lower the probability of termites coming through the basement walls.
  3. Pretreatment of the Concrete Slab – this involves treating the ground on which a building sits by applying termite control and prevention chemicals to it even before the concrete is poured. This is generally a very effective form of pretreatment, not only because of the soil treatments but also because of the added barrier of the concrete, which termites shall not be able to erode or penetrate.
