There are two main termite management systems used to protect buildings from termite attack
1) Application of termite treatment to the soil around and under buildings
2) Installation of a termite monitoring and baiting system around the perimeter of buildings
Following on from our previous article when we looked at how baiting systems protect your home from termites, we’ll look at the pros and cons of the soil termite treatment option.
A termite attack on your home can be an emotionally draining and expensive experience, with serious attacks realising damage bills up to $100,000 or more. Once active termites have been eradicated from the building, to prevent further attacks in the future (or prevent an attack in the first place), it is necessary to install a termite management system to protect the building.
When the soil is replaced, it is mixed with insecticide to create a treated zone around the property. For those buildings with a sub-floor, the soil under the house around all sub-floor structures (perimeter walls and piers) should also be treated.
In contrast, the newer non-repellent treatments actually kill termites that come into contact with the treated soil. Termites coming into contact with the treatment also have the potential to pass the chemical on to other termites, magnifying its effect. As termites cannot detect the chemical, they cannot find any potential gaps in the treatment, making it a more robust treatment compared to the older repellent chemicals. As such the newer non-repellent treatments tend to be a little more expensive. In addition, some of these newer non-repellent chemicals have an excellent environmental profile making them a smarter choice for those with pest and children.
It’s important to realise that a treated zone is not a “termite barrier” preventing termites from entering your home. They are designed to work with the structural aspects of your home (foundations, “ant capping”, etc), to prevent termites entering your home without being noticed. That is, to get into your home they need to build a mud tube around the barrier. When they do this, they can be spotted and dealt with. For this reason even with a soil treatment in place, it is important to have annual termite inspections. In fact, any treatment warranties will be reliant on having annual termite inspections as part of the ongoing termite management plan.
Clearly the success of any soil termite treatment is dependent on ensuring an even application of chemical around and under the property. If there are concrete paths or pavers around the property, it is possible to drill through concrete and pavers and inject the product into the ground. However, there is no way of knowing how even the chemical has been distributed in the soil and we believe it can give a false sense of security. If we cannot be confident of installing a complete, even soil treatment, we will always discuss other treatment options such as baiting.
Although soil termite treatments can be an excellent option in many situations, sometimes building construction, soil type and the gradient of the block means a chemical treatment cannot be applied successfully and other options should be considered. Always be careful of pest control companies who only push one treatment option.
Furthermore, a reticulation system can also be installed when the soil is treated. The reticulation is a series of flexible pipes laid in the ground around the property. These can be filled with insecticide when the soil needs to be re-treated. This makes future treatments quick and easy, without having to dig up soil and paths, resulting a very cost effective long-term option.
Only one property inspection per year is required to maintain warranty.
For most structures where a soil treatment is suitable, it represents the most cost effective termite management system for protecting homes.
New chemicals have a great environmental profile, only targeting termites – a great option for those with pets and children.
