The life expectancy of any termite barrier system or treatment depends on its type, chemicals and materials used, and who installs it. Believe it or not, but the termite barrier preparation is the key to a long-lasting termite barrier system.
How Long Does a Chemical Termite Barrier System Last?
Decades ago, homes were constructed with an “under-slab” termite barrier system. The chemicals used were cheap and only lasted up to a year as building firms wanted the certificated and were not concern about the chemical’s life expectancy,
Standard building practices dictated that when builders laid a slab, they need to install an under-slab barrier. However, builders called upon random pest companies who gave the cheapest quotes that only provided customers with a one-year warranty. These pest companies provided a quick spay before the slab was laid to satisfy the building regulations.
Thankfully, many have changed since then.
Improvements in termite prevention technology have seen the advanced formulation of high-quality products. Some products at full strength can cover an average house of 70 linear metres.
This means 700 litres of this product is required to perform a perimeter termite barrier for most homes. This type of termite barrier system can last up to 8 years.
Effective Building & Consultancy considers the best product on the market and while there may be cheaper alternatives, they often have a shorter life expectancy.
10 years ago, the use of certain chemical brands followed a popularity trend. However, with the technological advancements in pest control techniques, education, research, and equipment, products have become more effective, more efficient, and less harmful to the environment.
In the early 2000s, legislation changed and the building code stated that one couldn’t use a chemical treatment on a new house build unless it was replenishable. In other words, chemicals could be added over time to ensure it’s effective. This was an expensive option for builders, which led to the more suitable physical termite barrier system.
How Long Does a Physical Termite Barrier System Last?
A physical termite barrier system is a plastic barrier that is laid out around the house perimeter during construction against the brickwork. After 2001, the physical barriers are a compulsory part of the building code of practices and applies to all homes.
These types of systems last for 20 years. This may sound too good to be true, however, what’s often misunderstood about physical barriers is they’re only a piece of plastic acting as a deterrent.
The problem with this is that a small crack in the slab and termites are in. A perimeter termite barrier type of products is designed to affect and eliminate the termite colony as these travel through the soil towards the home.
Even if a physical termite barrier reduces the risk and is better than having no barrier at all, it’s still not as effective as a chemical barrier. This is because chemical barriers are designed to kill off the termites completely.
How Long Do Termite Bait Stations Last?
Termite bait stations are different from physical and chemical termite barriers in the sense that they’re designed to act as early warning indicators. In other words, they’re placed around the yard that gives the homeowner a chance to act before any potential damage is done to the home.
Unlike the barriers, termite bait stations need to be checked and replenished at least monthly. When active termites are found a bait using an insect growth regulator is added to eliminate the colony close to the home.
Termite bait systems are a great way to protect your home but usually only suited for homes on sloping sites.
A Longer Lifespan Doesn’t Mean Longer Efficiency
Some products on the market promise a longer life expectancy of about 10 years. However, this is often misleading and inaccurate.
For example, biferenthin may have a longer life expectancy, but unlike termiticide, it acts as a repellent. Termites detect products like bifenthrin in the soil and will avoid it, making it useless. When this happens, termites will just work around the product and make their way to your home.
For this reason, Effective Building & Consultancy building and termite inspectors rely on the chemical termite barrier system because of its effectiveness. Termites can’t detect it and will pass through the chemical, return the product back to the main nest which eliminates the colonies completely. This is the reason why chemical termite barrier system is highly preferred in the industry.
How Much Do Termite Treatments Cost?
The cost of termite treatment depends on the kind of termite barriers or termite baiting systems you will purchase. Each home is different that’s why it’s important to book a consultation with our building and termite inspector to assess the home type and land layout so the right recommendation can be made.
