What Are Termite Risk Management Systems for Homes in NSW?

Termite Management Systems focus on installing chemical or physical products to deter termites from infiltrating buildings and they will be a blend of chemical and physical barriers.
These systems are commonly referred to as “pre-construction” treatment zones because they are installed at the beginning of a new building project or renovation.

When building a new home in New South Wales, builders must integrate termite risk management (TRM) systems during construction to protect your home from potential infestations.

Australia enforces standards such as AS 3660.1, which outlines the requirements for designing and constructing subterranean termite management systems. Most often, it is a termite reticulation system or a termite barrier. These are both physical and chemical barriers designed to deter termites from damaging your home.

In areas with high termite activity, selecting appropriate termite management strategies is paramount. Factors such as soil type, climate, and known termite presence in specific regions play a significant role. Make informed decisions on termite management for new building work to ensure your home remains protected for years to come.

Termite Biology and Behaviour

Termites are social insects and live in large colonies and they play a critical role in nature to break down cellulose. What home owners want, is to attract these colonies to set up residence in their homes.

Species Prevalent in NSW

In Sydney, the three termite types that cause the most damage to homes are primarily subterranean species. These include:

1. Coptotermes acinaciformis

• Habitat: These termites are commonly found in eastern New South Wales and southeastern Queensland, particularly along the coastline and the Great Dividing Range.
• Behavior: They construct large colonies underground and can build subsidiary nests in wall cavities where moisture is present, such as from leaking pipes or gutters.
• Damage: Coptotermes acinaciformis accounts for around 70% of termite destruction. They are highly destructive to all timber structures, causing significant damage to foundations, support beams, and other wooden components of buildings

2. Schedorhinotermes intermedius

• Habitat: This species is prevalent throughout New South Wales, especially in urban areas where buildings are constructed with timber framing.
• Behavior: They build nests in tree stumps, root crowns of living or dead trees, and under houses or patios where timber is in contact with soil.
• Damage: Schedorhinotermes intermedius is responsible for a large portion of timber damage in the NSW region, attacking structural and decorative timbers in buildings

3. Nasutitermes walkeri

• Habitat: These termites are found in coastal regions and are known for their distinctive nests, which can be arboreal or located in tree stumps and logs.
• Behavior: Nasutitermes walkeri termites build large, conspicuous nests and are less aggressive compared to other subterranean species.
• Damage: While not as destructive as Coptotermes or Schedorhinotermes, they still cause significant damage to wooden structures, particularly in areas with high moisture content

Regular termite inspections and preventive measures are essential to protect homes from these destructive pests.

Understanding Termite Needs

Termites have specific needs that drive their behaviour and colony establishment.
Moisture is critical for their survival, influencing their habitat selection. They thrive in areas with consistent moisture sources, such as leaking pipes or damp soil.

Termites feed primarily on cellulose, found in wood, paper, and other plant materials. This diet makes homes with wooden structures particularly vulnerable. Properly managing moisture and eliminating food sources can significantly reduce the risk of infestation.

Temperature also plays a role, as termites prefer warm climates. Maintaining your home and its surroundings in a way that disrupts these conditions can help deter termite activity.

Assessing Potential Termite Risk

Environmental conditions significantly influence termite risk. Being close to natural habitats such as bushland increases the likelihood of termite infestation. Additionally, vegetation close to your home can provide a bridge for termites to enter the building.
Homes in The Hills District are in prime termite territory.

Home builders are responsible for providing a termite risk management system during construction.

NSW Building Codes

In NSW, building codes mandate that builders install effective termite risk management (TRM) systems in all new constructions. The NSW Fair Trading outlines that the building contractor must provide a comprehensive TRM system as part of their service.

Standards like AS 3660.1 outline the requirements for designing and constructing termite management systems in Australia. These guidelines help ensure compliance with the best practices for termite prevention.

These systems are designed to prevent termites from accessing the structure and causing significant damage.

Physical barriers might include graded granite stone or stainless steel mesh, while chemical systems involve soil treatments or a reticulation system with termiticides.
The AS 3660.1 ensures these systems are robust, long-lasting, and effective in deterring termites from entering the built environment, offering a guideline that all builders and contractors must adhere to rigorously.

Local Council Requirements

Local councils in NSW also play a crucial role in termite risk management. Councils may have specific requirements or additional regulations based on the local termite risk assessments. For example, areas with high termite activity may mandate more stringent termite management practices. This is a Fact Sheet from The Hills Local Council

Builders and homeowners should consult their local council to understand any additional requirements that may apply.

Termite Risk Management Strategies

Effectively managing termite risks in new homes in NSW involves utilising a combination of physical barriers, chemical treatments, baiting systems, and integrated approaches. Here’s a detailed look at each strategy to help you safeguard your property.

Physical Barrier Systems

Physical barrier systems are essential in preventing termites from entering your home. These barriers are often made from materials like stainless steel mesh, crushed stone, or graded particle barriers, which termites cannot penetrate.

For instance, stainless steel mesh is installed during the construction phase and acts as a long-lasting barrier against termite invasion.
Crushed stone barriers, another popular option, are placed around the perimeter of your home, forming an impassable layer for termites.

Physical barriers are most effective when used in conjunction with other termite management strategies. Regular inspections are also necessary to ensure that no soil movements or disturbances have compromised these barriers.

Chemical Soil Treatments

Chemical soil treatments involve applying termiticides to the soil surrounding your home. These chemicals create a protective zone that kills termites upon contact or repels them from the treated area. Common termiticides used in these treatments include bifenthrin, fipronil, and chlorpyrifos.

Application methods can vary, but it often involves trenching and treating the soil or injecting the termiticide solution into the ground. It’s crucial to hire professional pest controllers for this task to ensure proper application and safety compliance.

Chemical soil treatments can provide long-term protection for several years, but regular reapplication is recommended to maintain effectiveness.

Reticulation System

These are similar to The Chemical Soil Treatments and these are installed during the build or when renovating. The system uses a termiticide, like the chemical soil treatment, but it is released through a hose or reticulation set up. The chemical is released into the ground through perforated holes. We install the pipe around the building’s foundation.
This system works well when your home has pavers or hardscaped areas around your home. Once the system is in place there is no need to distub the pipes and it is easy to replenish the chemicals.
Many property owners request a reticulation system for their new buildings, or when they renovate the building – Read more about Termite Reticulation Systems

Baiting and Monitoring Systems

Baiting and monitoring systems are also options for managing termite risks. We have to install these when we do find termites. These systems utilise bait stations placed around your property, filled with cellulose-based baits laced with slow-acting toxins.

When termites consume the bait and return to their colony, they spread the toxin, leading to the colony’s eventual elimination. Regular monitoring of the bait stations is crucial to assess termite activity and ensure the bait remains effective.

One of the advantages of baiting systems is their minimal environmental impact, making them an eco-friendly option. However, patience is required as full colony elimination can take several months.

Integrated Management Approach

Using a mix of physical barriers, chemical treatments, and baiting systems tailored to your specific property needs is always going to have the best protection for your home.

Regular inspections by licensed pest controllers are integral to this approach, ensuring early detection and prompt action against termite activity. Preventive measures, such as maintaining proper drainage, reducing wood-to-soil contact, and eliminating moisture sources, are also essential components.

Post-Construction Termite Management

Ensuring your home remains termite-free requires consistent maintenance and proactive measures. This section covers essential aspects including maintenance schedules, regular inspections, and homeowner awareness.

Additionally, make sure to repair any leaking pipes, dripping outdoor taps and clean and maintained gutters that are not overflowing when it rains
Moisture near the foundation can undermine previous termite treatments and create new infestations.

Regular Inspections

Regular termite inspections are vital to identifying early signs of termite activity.
Schedule professional inspections at least once a year to thoroughly examine your home, including roof cavities and crawl spaces.
Every termite management system has its own advantages and disadvantages in terms of cost and environmental impact. No system is foolproof, as termites have been known to find their way around treatment zones. Therefore, it is of utmost importance to have your home regularly inspected by a licensed, professional pest controller to identify any signs of termite activity.

Certain systems may require periodic professional inspections to maintain the validity of their warranties. Therefore, it is crucial to stay informed about any specific requirements. Regardless of the chosen protection system, it is the responsibility of the property owner to ensure regular professional inspections are conducted.

Look out for tell-tale signs like mud tubes, discarded wings, or damaged wood. Termites often leave these indicators as they infiltrate and settle into your home.

Lastly, inspect high-risk areas, such as wooden decks and fences, regularly. These inspections can help detect and address an infestation before it becomes severe, saving you significant costs and stress.

Homeowner Awareness and Prevention

As a homeowner, staying informed about termite behavior and preventive measures is key. Avoid storing wood piles and mulch close to your home’s foundation, as these can attract termites. Also, maintain a gap between the soil and any wooden parts of your building to deter subterranean termites.
Knowing how to spot initial signs of termite activity can lead to quicker action and effective management.

Termite Eradication Procedures

If a termite infestation is confirmed, prompt eradication is vital.
Chemical treatments, such as termiticides, are often used to create a barrier that termites can’t cross. Liquid treatments are applied to the soil around your home’s foundation or directly to the infested areas. Baiting systems can be deployed to attract and kill termites.
