Importance of Termite Barriers in Queensland
Termites are a major problem across the entire Queensland. The northern region is most affected but all areas are prone to termite attacks. The history of termites in Australia dates back over 250 years ago. That’s why, you’ll find some with so hardened nests protruding above the ground. Queensland is Australia’s second largest state after Western Australia. It’s common for our inspectors to find eveidence of termite activity when we inspect houses for asbestos. In fact termite infestations and asbestos containing materials go hand in hand in our industry.
In a recent chat with Scott Dixon who specialies in pest control Gold Coast, he outlined that termite inspections were in high demand across South East Queensland. Moreover he also mentioned that termite barriers and baiting system were installed by around 80% of customers who they inspected properties for. He said the importance of termite barriers for property owners was evident from their sales statistics.
An industry survey conducted in Queensland established that a third of all unprotected properties are under subterranean termite threat. For home owners to protect their homes, they have to adopt tough preventive mechanisms.
Termite barriers are one of the governments approved termite control mechanisms. They are special materials designed specifically to prevent subterranean termites from accessing structures. Thus preventing their wanton destruction.
The building code of Australia (BCA) recommends the installation of termite barriers before construction begins. Whether a commercial building, a residential or an extension, termite barriers are very important.
Types of termite barriers
1. Chemical Barriers
You can consider using approved chemicals under the slabs and around the building after completion. To set up a chemical barrier, construct a 300mm wide concrete. This will act as the protection strip. Once complete, top up the chemical with a reticulating system.
Though chemical barriers are effective in keeping away termites, they don’t last long. You have to repeat the same process every now and then. Having to constantly refill the chemical can be expensive. Remember nothing is free. You have to purchase everything.
Besides preventing termite’s invasion, the chemical used can eliminate an entire nest of termites. When one termite carriers the poisonous chemical back to their hole, it kills all the others. Though armful to the termites, a chemical barrier is very safe for humans, home animals and pets.
Factors to consider before choosing a chemical termite barrier
1. Dimensions of trenches
The termite chemical should be able to penetrate at least 300mm below the soil. So, the termite technician should dig a trench that fits these requirements. Otherwise, a shallow chemical will not offer protection from termites living underground. Although, that should not be at the detriment of other properties. You should avoid damaging pipes and garden around your home.
2. Access holes
These are small access holes drilled below the concrete slabs. They are usually between 200mm to 300mm apart and must be sealed after inserting the chemical. The holes are used to get the chemical to the soil under the slabs.
3. Quantity and chemical concentration
An effective termite barrier depends on amount you apply per meter. Using ten litres of chemical per meter is a good quantity that can give you good results.
4. Chemical type
Not all chemicals are effective in creating an effective termite barrier. Your choice of chemicals should be on basis of the area and the property. Certain places are more susceptible to termites than others. In such areas, you have to use stronger chemicals. Your technician should conduct a thorough analysis and recommend the best chemical.
2. Physical Barriers
Physical termite barriers are usually used during renovation projects or during construction of new buildings. Building foundations develop cracks with time where termites can fit in. that is why barriers should be installed during the beginning of construction to prevent future termite infestation.
Best physical barriers
The efficiency of your physical barrier is greatly dependent on the materials you use. Their quality, sturdiness and durability. Below are the best physical barriers you can go for;
Stainless-steel mesh
Mesh under the slab does great in keeping termites away from accessing your building. You may put it partially or fully under the slab. You can also lay it all-round the perimeter.
Resistant timbers
You can opt to use treated timber or natural resistance timber. This is important as it provides a more lasting solution.
Materials resistant to termites
To keep away termites now and in the future, its best to use termite resistance materials. These include materials such as; masonry, steel, fibered cement, concrete or treated timber. These act as long-term termite barriers.
Graded Stone
You can place graded stones can below the foundation slab. You can also do the same all around the perimeter wall.
Physical termite barriers provide long term barriers against termites. They are also cost friendly.
Conclusion
If you live in Queensland, you can use any of the two types of termite barriers. They are both effective. To ensure your home is always safe from termite invasion, consider inspecting your termite management systems regularly. Also, always meet the yearly maintenance requirements. This way, your property will be safe from the termite menace that has terrorised people for years. Always hire licensed pest control company that specialises in termite identification and treatments.
