People in the market for a termite control method they can trust have a slew of options available to them, from the barrier methods to the termite baiting tactics. One method of termite prevention that deserves to be one this list—albeit in the special category of methods executed before a structure is finished—is that of termite pre-treatment. Termite pre-treatments include any of various processes whereby the soil that surrounds and rests under a structure being constructed at the time of treatment is infused or impregnated with termite-repelling chemicals and insecticides. It is in a sense similar to the barrier method most of us are familiar with, as it also erects a pesticide barrier around the foundations of the building, but is different in that it is executed even before the building is completely built—hence the name “pre-treatment”.

A termite pre-treatment may cost quite a bit more than other termite control methods, most especially if the type of soil at the area of treatment is difficult to work with and requires specialised chemicals, or perhaps if the lot is large and requires a big volume of termiticide to be adequately protected. What is the exchange for this cost, then? Simply the sheer efficacy of the application: most pre-treatments, when executed by properly trained professionals with good materials available to them, can actually outperform similar chemical barrier treatments executed after the construction of the structure is over. Hence, the building would have better termite prevention measures in place with a pre-treatment. Even the costs are not actually all that high, though they may seem to be at first glance: if similarly thorough barrier methods as those used in pre-treats were applied post-construction, the price would actually be higher due to the difficulty of getting in and around all sensitive areas.

Pre-treatments are also advised because they simplify the detection or identification of potentially vulnerable areas. When a structure is already completed, the task of identifying the problem areas and possible termite-channels is harder, because it is not possible to take apart certain parts of the building just for the sake of seeing the foundations better. With pre-treatment, the termite control technicians are able to inspect as much as they like and predict the problem areas in advance, treating them easily.

Take note, however, that even pre-treatments are not foolproof, nor indeed are they eternal. Even this method of termite control needs to be paired with another for better security of the home. The chemicals used for the termite prevention are also ones that eventually erode, so you shall need to provide for the loss of your primary barrier method later on, perhaps about ten years into your home’s age.
