An Overview of Soil Treatment Methods for Termite Control

Last Updated on

Termites, the scourge of homeowners and builders alike, are a prevalent issue that can undermine the structural integrity of any building. When these wood-loving insects infest your space, they can cause damage amounting to thousands of dollars. Hence, there is a burgeoning need for effective methods to ward off these unwelcome guests.

In this comprehensive guide, we’ll delve into soil treatment techniques for termite control, a crucial step in establishing a termite-free environment for your residential or commercial structure.

Why Soil Treatment?

Before we venture into the methods, it’s vital to understand why soil treatment is essential. Termites thrive in soil, using it as their primary residence before invading wooden structures. By treating the soil, you’re essentially cutting off their supply routes and making the environment inhospitable for them. Soil treatment acts as both a preventive measure and an intervention, ensuring that your construction remains resilient against termite invasion.

Pre-Construction Termite Control

If you’re building a new home or commercial property, implementing termite control during the construction phase is often the most efficient way to prevent future infestations. For more information on pre-construction strategies, be sure to check out pre-construction termite control.

Chemical Termiticides

Chemical termiticides are typically the go-to solution for most professional pest control services. These chemicals – which include pyrethroids, neonicotinoids, and phenylpyrazoles – are applied to the soil, forming a barrier that either kills or repels termites. Depending on the active ingredient used, termiticides can provide long-lasting protection ranging from 5 to 20 years.


  • Long-term effectiveness
  • Rapid action
  • Suitable for large-scale applications


  • Potential environmental hazards
  • May require professional application
  • Restricted use in some areas due to regulations

Borate-Based Treatments

As a more environmentally friendly alternative, borate salts can be applied to the soil to deter termites. Borates disrupt the termite’s digestive system, leading to their eventual demise. This method is often used as a supplement to chemical treatments.


  • Environmentally friendly
  • No toxic fumes
  • Easy to apply


  • Shorter effective duration
  • May require re-application
  • Less effective on certain termite species

Biological Control Agents

Biological agents like beneficial nematodes can also be introduced into the soil. These microscopic worms infiltrate the termite colonies and infect the termites, usually resulting in their death within 48 hours.


  • Non-toxic to humans and pets
  • Eco-friendly
  • Target-specific


  • Limited effectiveness in large infestations
  • Requires specific environmental conditions to work
  • Short lifespan requiring frequent re-application

Heat Treatment

For smaller, accessible areas, heat treatment can be an effective solution. This method involves raising the soil temperature to a level that termites cannot withstand – it’s a rapid, chemical-free way to kill termites on the spot.


  • Immediate results
  • No chemical residues
  • Suitable for localised infestations


  • Not applicable for large-scale treatment
  • Temporary solution
  • High energy consumption

Final Thoughts

Termite control is an essential aspect of building maintenance and construction. While each soil treatment method has its own advantages and drawbacks, the ultimate goal is to establish a termite-free zone that safeguards the structural integrity of your property.

Whether you opt for chemical treatments, borates, biological agents, or heat treatment, the critical aspect is to choose a method that aligns with your specific needs and environmental concerns.

Before making a decision, consulting professionals in the field is always advisable. They can provide an in-depth analysis of your specific situation and recommend the most effective, tailored treatment for your needs. Good luck!
