There are just a few of the over fifty species of subterranean and arboreal termites in Trinidad & Tobago that are of real economic importance. Both types will normally travel through the top 18 inches of the soil, foraging for a food source and will enter a structure through the ground slab. While some technicians like to emphasize a distinction between subterranean and arboreal species, there is little need to do so in terms of their foraging habits and how they would normally enter a building. The methods of pre and post construction treatments of foundations serve for both types of termites.
However, some companies use this distinction to actively market the direct treatment of arboreal nests over a full foundation treatment. While this will provide a complete kill of that colony, it does not offer long-term protection from any other colonies within the 100 meter plus foraging radius from the building. The game here is that over the estimated 10 year life of a full foundation treatment, a company may return many times to treat arboreal nests at a cumulative cost far greater than the full treatment. Additionally, the efficacy of the treatment will be determined by the class of termicide used and the degree of observance of the required protocols by the technicians.
When choosing a service provider, it is advisable to look for a registered and recognized company, preferably a member of the Pest Management Association of Trinidad & Tobago. A reputable company such as Ectercon will issue a warranty for the job, providing assurance of quality. EcTerCon provides a range of specialized, environmentally responsible products and systems designed to target wood destroying organisms like termites, powder post beetles, silverfish and fungal decay, with zero health and environmental impact.
