Subterranean Termite Treatment 

The ultimate aim of a termite treatment t is to separate a proposed structure or building from the subsoil.  In Barbados and the Caribbean, there are two methods to achieve this separation, The Pre-Construction and the post-construction method.

Termite Treatment

The Pre-Construction Treatment


A pre-treatment or pre-construction treatment is done before the casting of any concrete within the structure that will come into direct or indirect contact with soil.   


It starts with the foundation footings. After the footings have been dug and prepared for casting, a non-repellant termiticide is applied to the area. This is the first defense against termites that will try to enter the building from the soil after construction has been completed..


The second stage of the treatment is carried out after the floor slab area is prepared for casting.  Usually, at this time the marl-fill is rammed until it becomes hard and compact.   The termiticide is applied to the surface in specific amounts based on the square footage of the area. 


After this stage of the treatment is complete, the contractor or builder would place the damp-proof covering on the surface of the treated slab area.  Apart from intercepting the rising damp, the covering would trap the termiticide in the floor.  


It should be noted that if for any reason, the slab has to be cut for the placement of a pipe or a conduit, we should be informed, and corrective treatment would be carried out to the area.  There may or may not be a small charge attached to this.


Every new structure may not have a slab floor. Some may have crawlspace areas.  In such an event, after the floor is in position, the termiticide would be applied to soil adjacent to the support columns and to the perimeter walls. 

The third and final treatment would come after the home has been completed, and back-fill is put in place.  This would be explained in our section of Post Construction Treatment.


post Construction Treatment

A Termite Pre-Construction treatment is far better than a Post-Construction termite treatment. After your home is attacked by subterranean termites, the required treatment is Post-Construction Termite Treatment generally called a termite treatment.


The post-treatment is actually not as good or as thorough as a pre-treatment because 100% of the soil is covered, while in a post-treatment this cannot be achieved because of the location of pipes, conduits, and other hard to reach areas.


A series of holes are drilled into the perimeter walls, the load-bearing partition walls, and the external slab areas at regular intervals.   This is followed by injection (under pressure) of a non-repellant termiticide like Termidor or Premise 75 to each of the drilled holes.  All holes would be sealed and neatly plastered after they have been injected.


Termidor and Premise is a non-repellent termiticide that creates an invisible barrier between your home and the termites living in the subsoil.   Non-repellent products are not easily detected by termites, so they do not know to avoid the treated area. 


Forager termites are the first to confront these non-repellent products, which, on the termite's return to the colony, are then shared with the rest of the colony — effectively destroying the entire colony.  Any structure with well-built foundation walls will most likely receive our Five Year Warranty after treatment.

Exceptions to the Five Year Warranty rule may be houses with packed-rock or no foundations at all.

In Conclusion

Termite Treatment, whether pre-construction or post-construction remains one of the most important things to include in any new home construction as it helps to keep out these vile creatures and protect the structure from day one.


It is the least of all components of the building, and it will save you thousands of dollars in repairs.


If you skip the treatment, you leave the home vulnerable to infestation, and the first signs of termite activity can disrupt your peace of mind, and make you regret not making it a top priority at the start of your construction.
