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.


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 have been  dug and prepared for casting, a non-repellant termiticide is applied to the area. This is the first defense against that will try to enter the building, when completed, from  the soil.


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


After the application 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, and prevent disturbance of the slab. 


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 treatment should carried out to the area.  


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.



A Termite Pre-Construction treatment is far better than the 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 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.
