Termite Barriers – What You Need To Know

Which chemical should you choose?

Repellent vs non-repellents. Generic brands vs original brands. Which is the better protection for your home?

As you can see, the superior chemical penetrates further through the soil and has a more thorough bonding process with the soil to ensure no gaps are left open for the termites to go through untreated soil. Non-repellent slow-acting transfer chemicals (e.g. the Termidor/Termidor HE brands) are premium grade chemicals in the termite world. These are the products 9 out of 10 Blue Chip Termite & Pest Control customers use to protect their homes. This class of chemical does not affect the termites natural foraging process; hence the termite’s entire body is covered in the chemical and is then transferred through the colony workings (one termite kills multiple termites through the transfer effect). These types of chemicals are made to kill out any possible nests around your outer house walls and garden areas.

Repellent chemicals, known as blocking chemicals (the cheaper brands), are there purely to kill any termites that gain entry into the treated zone with no chance of the transfer effect of the non-repellent class of chemicals. Studies have also shown that termites learn from the repellent treated zones and continue foraging, increasing the chance of finding alternative entry into your house.

Generic non-repellent vs original non-repellent brands

Yes, they may have the same active ingredient, but it all comes down to how the chemical is put together and how well the chemical bonds together with the soil to handle different weather conditions and give you that long term protection and peace of mind that your house is protected for 8 to 10 years. BASF has designed Termidor and Termidor HE to be market leaders and the only chemicals that Blue Chip Termite & Pest Control stands by for their customers. You can find Blue Chip Termite & Pest Control on the BASF website under Accredited Applicators.

Treatment Process

Depending on the design of the house (e.g. if you have paved, concreted areas, or soil around the outer walls), the installation process ranges from trenching along the wall in unpaved areas to drilling between the grout line of tiles or along concrete paths. Termidor is designed to go up to 200 millimetre hole spacings apart, 150 millimetres out from the wall. The slightly more expensive product, Termidor HE, can go up to 450 millimetres apart and is designed for getting between those 300 and 400 millimetre tiles to minimise the damage.

A rough guideline for the amount of chemical needed is 10 Litres per lineal meter. In certain instances, less chemical can be used if the footings along the wall’s edge are not deep. Still, Blue Chip Termite & Pest Control never goes below 10 Litres per lineal meter to ensure thorough coverage.

In older houses, footings can sometimes go 450 to 650 millimetres below the soil height. In this situation, the rate of chemical per lineal meter will increase. This will all be noted during our onsite assessment and taken into consideration in our quote.

Chemical does not bond to areas with stones installed around the house walls or areas with heavy clay. In these situations, Blue Chip Termite & Pest Control will install a premium sandy loam soil type to ensure the chemical has the best protection and coverage for your house.

Areas that have loose bricks will be lifted and reinstalled after the treatment is complete.

Life of the Chemicals

In Australian conditions, chemicals last between 3 to 10 years maximum depending on the chemical type and the mix strength. 95% of Blue Chip Termite & Pest Control treatments last for between 8 and 10 years.

Why Annual Termite Inspections Are Still Required After Chemical Barrier Treatments

Chemical barriers protect your home from subterranean termite attack, which is the most common termite attack to buildings. However, there are also dry wood termites and damp wood termites which can fly into the side of your home and start a colony by laying eggs inside your timber without ever having ground contact. These two types of termites are a lot less common but are just one of many reasons why on-going annual inspections are still essential.

Termites are complicated and can be expensive to treat as well as repair any damage. In Australia, homeowners cannot get insurance for termite damage. Yet another reason why annual termite inspections are so necessary.

The importance of keeping up regular termite inspections

Termites are considered one of the most successful species of insects on earth, with 16 known species having an economic impact in Australia. Their colony sizes can range from a few hundred, to enormous societies of several million, described as superorganisms. Termite queens are known to have the longest lifespan of any insect, reportedly living for up to 50 years! As many home owners would be aware, termites can do significant damage to buildings and wooden structures due to their feeding and decomposing of cellulose, generally in the form of wood. Their ability to remain concealed until severe, and sometimes irreparable amounts of damage are done to wooden structures are their greatest strength and our greatest threat.

The importance of termite inspections

Buying your own home may end up being the biggest asset you will ever own in your life! Now imagine if on top of your mortgage and all the other usual payments you have to make towards owning your own home, you have to add thousands more on top of that due to extensive termite damage to your house. These costs can be easily avoided with regular termite inspections, or a termite inspection prior to purchasing a home. The best way to handle a termite situation is preventatively. With regular inspections you will be able to catch the termite attack in it’s early stages and eliminate a smaller colony before they are able to grow and cause significant structural damage. If these pests are left to run rampant and eat away wooden structures, they can cause severe damage such as:

  • Causing floors to buckle and cave in;
  • Walls thinning;
  • Ceilings to droop down; and
  • Doors and windows warping.

If left untreated, your home may end up unliveable and unsafe.

What’s involved in a termite inspection

Termite inspections should be completed as per Australian industry standards. You will be asked if you’re aware of any history of termite problems, or if there are any issues you may have noticed around the house that could be related. A check of the fence lines, gardens and lawn areas, outer walls, subfloor and roof voids, and all internal walls will be completed to identify any signs of termite damage or activity. Your doorframes, window frames, shower and toilet wall backings will also be thoroughly looked over with a moisture meter, and if any readings come up in any of those areas, they will be gone over again with a termite radar to ascertain if there’s any potential termite movement in the walls. These inspections can vary in time frame depending on what is found, and a written report with any photos problems, and recommendations will be emailed to you at the conclusion of the inspection.

There are a number of ways to reduce the risk of termites, such as:

  • Fix any moisture issues like leaking pipes, poor ventilation, and poor drainage;
  • Keep any areas under the house (if there are any) clear, and don’t store anything that can reduce the ventilation of that space;
  • Remove any spare wood that is in contact with the ground and close to the house; and
  • When building a new home, certain construction materials and methods can significantly reduce the risk of termite attacks, so speak with your construction contractors about this.

Get regular termite inspections, at least annually, and follow their advice to reduce your risks.
What these annual inspections will cost is nothing in comparison to the time and money that termites drain once they’ve burrowed their way into your homes. Don’t let termites eat away at your peace of mind and bank balance. Organise your inspection today.
