See what termite nests look like in trees, something that we look for during every termite inspection.

Building using recycled materials certainly makes ecological sense, however, they need to be understood so as to be used most effectively. Used railway sleepers are often used in new building work, but they are usually not treated and can also be a problem when attached to a building. It's best to avoid using any recycled susceptible timber if it comes into contact with the ground.

These timbers will negatively impact both a physical and chemical barrier.
Why regular inspections are important.

Regular termite inspections are an important part of any home maintenance program, as can be seen by this photo. The homeowner was getting a regular inspection when these mud tubes were noticed with termites building them up. This indicated that termites were living in the subfloor and it would only be a matter of time before they would find their way into the timber of the house.
Will Ants keep Termites Away?
It's a common theory - if you see black ants around your house, the it's safe from termites! Well, this video will answer that question with a demonstration of the interactions between Black garden ants and Termites
Ants Vs. Termites
Treated timber. Getting eaten out!

Manufacturers of treated timbers my warrant it against termite attack, however, if you carefully read their terms and conditions, you'll notice that they won't warrant timber that's in ground contact.

If you look at the warranty brochure for this treated pine frame, you'll notice that things such as storing the timber on the ground, in high moisture environments or anywhere that can cause fungal decay will void the warranty. So be careful not to rely just on treated timber to prevent termite damage.
By and large, termite treated timbers do work well in resisting termites, but only if they are used in accord with good building practice and the treated timbers manufacturers recommendations.
When Termite barriers go wrong....
This post explains and shows why physical termite barriers fail, they're all designed to work. So why do things go wrong?
Read MoreKeep checking reticulation!
Termite management systems, by and large are effective. However, problems often occur after reticulation systems are installed. Often there are delays in building and hence exposes the reticulation system to damage to other trades being on site. This isn't necessarily always the fault of tradesmen on site, as they are usually not expecting a reticulation system being buried around the perimeter of the building. It's important to have good communication with the builder and tradesmen on site and also to keep a watchful eye on reticulation to ensure its safe after installation. That being said, reticulation is a great termite control method if it's done correctly!
This reticulation system was treated quite unkindly by builders/tradesmen!
This reticulation system has not been considered by tradesmen on site.
Kitchens are termite food!
It's often accepted that termites only eat complete timber in service, and are not interested in consuming particleboard, MDF or other engineered materials. However, this picture clearly shows that termites will consume chipboard and cause significant damage. In this particular instance, the termites ate out the kitchen carcass and it required replacement. So even if the building is constructed of termite resistant materials, it's important to protect the whole building and not just have some elements that are termite resistant.
Repellant vs. Non-Repellant chemicals.

Many new chemicals in pest control are touted as "non-repellent". What does this mean?
A non-repellant chemical has many advantages, specifically when dealing with termites.
Termites forage for food and may come into contact with a chemical barrier around a house in doing so, if the barrier is repellant, that is to say, the termites can detect it and avoid it, then there is a potential for them to locate somewhere around the perimeter of the building where they can enter. Hence, a barrier that is repellent can fail if the chemical has not been applied evenly around the perimeter through all potential entry points.
A non-repellent chemical treated zone does not repel the termites, but instead, allows them to enter the treated soil to such an extent that the termites are affected and after a period of time, they die off. The benefits of this treatment are apparent in the photos above. Not only does it prevent the termites finding the non-treated section of the barrier, but it also can kill many termites due to the delayed action of the chemical. In some instances, the transfer of chemical from one termite to another can be so prolific that the whole colony can be eliminated!
