Which Termite Treatment Is the Most Effective?

Termites, which are often called “silent destroyers”, are pests that can infest your home and cause devastating damage. If these house pests are feasting on your property, don’t expect them to leave voluntarily. Instead, get a termite treatment right away so you can prevent your property from further damage and save you money from more expensive repairs.

There are several ways to treat termite infestations, but the two most popular termite treatment systems are the Chemical Termite Barriers and In-Ground Baiting Systems. How do you know which one to use? In this article we outline these two treatment systems, how they work and when they are applied, as well as explain some of the older termite treatment methods that are no longer considered to be effective.

For specific advice on the best termite treatment for your home or investment property, its best to arrange a termite inspection with a licenced inspector in your location. Contact the Inspect My Home office on 1300 337 447 or book an inspection online. Your inspector will be able to advise on which treatment option will work best for you.

Chemical Termite Barriers

A chemical treatment is a termite control measure that establishes a continuous treatment zone within and around your house. It acts as a barrier to prevent termites from digging through the soil, entering your property and ultimately infesting the structure.

1. Trench and Treat

Creating a trench-line excavation around the perimeter of the house, then treating the trench with a non-repellent termiticide, refilling the excavated hole with soil, and treating the back-fill again. This chemical barrier system can provide and effective means of termite control on your structure for up to eight years and can be replenished.

2. Drill and Inject

This procedure involves drilling tiny unnoticeable holes through the slabs, external paths like driveways, expansion joints, and around the perimeter of the property. A non-repellent termiticide is then injected underneath every hole using a soil rod as a treatment. Holes are sealed back after the treatment injection is completed.

The non-repellent termiticide solution does not kill the treatment-exposed termite instantly but allows it to survive and return to the nest, infect all the termites, and eliminate the entire colony.

In-ground Baiting Systems

In-ground baiting systems are also very effective in controlling a major termite infestation. The baiting system is set up by installing 24 small plastic bait stations strategically located around the perimeter of the property. These small bait stations have cellulose inserts like wood, paper, or cardboard which will serve as termite food.

A chitin synthesis inhibitor is applied when the termites discover the food sources. This chemical slows the growth of the termite, prevents exoskeleton (external covering for support and protection) moulting, and causes them to die as they are unable to grow and form a new exoskeleton. Once a carrier termite spreads the insect growth regulator into the nest, the entire colony will be eliminated very shortly.

We recommend to have a one-year program with a regular servicing interval of four to eight weeks for the best termite control and elimination outcome. We carry out an annual bait system service thereafter.

Which is the Most Effective?

The most effective termite treatment for your property depends on several factors;

  • how the property is constructed,
  • the soil type,
  • slope of the block, and
  • whether any construction flaws exist.

Knowing these factors along with the professional help of termite controllers will dictate the best and most effective termite control system for your property.

Construction type

The most suitable termite treatment for homes depends on how it is built. We recommend a chemical barrier for slab homes. In the case of split level homes, baiting will provide the best outcome.  When the structure has construction flaws, neither of the two termite control systems will stand alone to control your termite issues. A combination of both chemical barriers and the baiting system will work best instead.

Construction Flaws

Many properties have construction flaws in them, leaving some areas of the structure unprotected and penetrable by termites. With these construction flaws, termites can find holes even with a complete treatment placed around your home. The best way to deal with this problem is by applying the combination of a baiting system and soil treatment. If your property has concrete and pavers around it, make sure to cut and lift them so you can treat the soil underneath.

Soil type

The soil type will also dictate whether a chemical barrier or an in-ground bait system should be implemented. If the soil is rock-barren and ideally sandy loam type, a chemical barrier system is better to use because the liquid soil termiticide will be easily and evenly distributed.

Slope of block

Another factor that can affect your treatment choice is the slope of the block. Blocks that are sloping steeply are difficult to treat with liquid soil termiticide. The risk of washing away the treatment when rain occurs is highly probable thus making the chemical treatment ineffective. If you have a steep slope on your block, opt to implement the termite baiting system instead.

Older, Cheaper Treatments

In the old days, pest busters used “repellents” as a cheap option to control termites. Repellents are pesticides that only deter termites rather than destroy their colonies and ultimately eliminate them. In other words, they aren’t considered an effective treatment system. Termites will avoid the specific areas that are treated, which will only trap them inside your property.

Another cheap remedy is to install a physical barrier made up of plastic or steel before the brickwork. This procedure is believed to prevent termite penetration by sealing any gap or opening towards the foundation. But in reality, these physical barriers are not effective in the sense that when foundations wear out over time, cracks can give way to termite access.

Regular Termite Inspection

Termite problems in Australia are widespread. If left undetected, a termite infestation can cause damages amounting to tens of thousands of dollars. You can help prevent this by having a regular termite inspection where expert pest and building inspectors can discover early signs of termites and advise on the most effective way to fight it.
