Frequently asked questions (FAQ)

Q. How do the Termguard systems work?

A. They are unique in its design and enable an equal distribution of solution within a 15% variation. The design of the pipe and the placement of the holes in the pipes create a reservoir that enables the whole system to fill prior to any solution dispersing from the holes.

These diagrams show the placement of the holes in a cross section view.

The holes are placed in the top 20% of the pipe and are installed facing upwards. This enables the system pipe to fill totally before beginning to emit any solution.

This also is how the systems deliver such an equal distribution of solution. A solution pumped through a perforated pipe will follow the path of least resistance. Therefore, in a simple reticulation system of perforated pipes, the pressure at the first hole along a pipe will be higher and therefore more solution will flow through the first hole compared to the last hole along the same system.

This presents problems for delivering equal amounts of solution. Termguard has solved this problem by adding a manifold that equilibrates the pressure at all the holes in the system to deliver equal amounts of solution from the first through the last holes.

Q. How are the holes in the perforated perimeter pipe kept free from obstructions, especially construction fill?

A. By the use of Permecover – a GeoFabric non-woven mat that keeps the construction fill from blocking the perforated pipe. Permecover also contains the termite management agent within those areas of construction that require a termite management barrier.

The use of clean unwashed sand/soil is used with the placement of the pipe with less than 10% rock content, which provides for equitable movement of the delivered termite management agent.

If small particles of sand/soil enter into the pipe trough the perforations the next delivery of termite control agent will push the soil particle to the end of the run of pipe where a drilled end cap will allow it to pass out of the system.

Q. What is the placement depth of the system?

A. The correct placement of the 3/4” perforated pipes is essential for the Termguard System to work. The requirement for pipes placed under the slab is different from the placement of the Termguard Perimeter System. The perforated pipes that are placed under the slab must be installed with at least 80% of the pipe below the finished pad level and the holes in the pipe must be facing upwards.

The Termguard Perimeter System is installed below the finished ground level and with a Permecover sleeve. The pipe is placed approximately 3” below the finished ground level and must be within 6" from the edge of the footing or brickwork. The holes in the drilled pipe must also be facing upwards for the system to deliver an equal dispersion of Termite Management Agent.

Q. Is the structural performance or integrity of slab construction affected by the impact of the appropriate volume of liquid when applied through Termguard systems?

A. No, the performance and integrity of the slab would not be affected, because the maximum volume of liquid that is put through the Termguard System at any one time never exceeds 1 gallon per 10 square feet of soil area. This application rate is equivalent to 0.2 inches of rainfall and will only be applied on a 3 to 5 year basis. Trials have been conducted on even the heaviest of reactive soils and the volume applied by the Termguard systems were insignificant to soil moisture conditions caused by rain from season to season.

Q. Do the termite management agents effectively bind to the target areas and not leach from the desired areas of treatment even if subsequent wetting occurred?

A. From an environmental standpoint, Termguard systems are the perfect choice for keeping termites out of the home or building. The termite management agents used are insoluble in the soil, so the barrier stays exactly where it is needed and will not be leached away by rainfall or the water in of lawns and gardens.

The termite management agents, approved by Termguard, for use within the system are non-systemic, which means that garden plants and other vegetation will not translocate the barrier away from the treated area where it is most needed.

Q. Does the termite management agent affect the home/building owner’s family and pets?

A. All termite management agents approved for use in Termguard Systems are manufactured in accordance with the highest EPA specifications relating to termite management products.

Most importantly, they bring real 'peace of mind' protection with the knowledge that it will not create health concerns for the building owner, family or pets and are environmentally responsible.

Termguard appreciate that some people can be severely allergic to prescribed medication and/or a variety of household products such as washing detergents, paints, insecticides or even cosmetic items. Termguard also recognize that personal medical conditions need to be taken into account at the time of termite management applications.

Q. Does the home/building owner have to be present when replenishing the termite management agent?

A. Another of the unique features of the Termguard Systems is that all systems are injected or replenished via external injection points which are located in the pathway or garden bed or landscaping of the building and are protected by a locked child proof trap. Therefore, the home or building owner is not required to be present at the time of replenishment however; all inspections require full internal and external access to the building.


Q. How often is the home/building owner required to have the system inspected?

A. It is highly recommend that inspections be undertaken at least 12 monthly and 3 to 6 monthly in high-risk termite areas. These recommendations relate to all termite management systems.

The manufacturer’s of termite management agents have varying times recommended for replenishment of their product, but experience shows that Termguard Systems should be replenished at least every 3 to 5 years. The licensed Termguard inspector will be able to determine when the replenishment should be undertaken when inspecting the property.

Q. What costs are involved in maintaining the systems?

A. The cost of maintaining the system is far outweighed by the potential damage termite activity can cause to the home/building. To maintain any warranty provided, regular Timber Pest Inspections need to be undertaken and these costs are relatively inexpensive in comparison to the piece of mind they provide to the owner.

Replenishment of the Termguard System will occur every few years and once again, these costs are miniscule in comparison to the costs incurred in repairing damage caused by termite activity to the building and are far more economical and less disruptive than the traditional methods used when retrenching soils areas and re-drilling externals paths and concrete areas.

Q. Can the Annual Inspections or Replenishment of Termguard Systems be carried out by the home/building owners’ choice of Pest Manager?

A. The Termguard Systems can be inspected or replenished by a professional pest manager of your choice, but due to the unique features of the systems, only licensed Termguard inspectors have:

• Details of how the system was originally installed,
• Dimensions of the system,
• Amount of termite management agent originally applied,
• Amount required for replenishment
• Been trained in the injection protocols, which include the use of specialized injection equipment.

The Termguard warranty will only respond if licensed Termguard inspector’s carry out the inspections and replenishment.

Q. Is it difficult to audit or monitor the amount of termite management agent dosed underground through reticulated systems hidden beneath buildings, which could pollute the underground water?

A. The development of current and future termite management agents have and must continue to meet the criteria of being stable within their environment and ensure that they bind to the soil. There has been NO underground water issues in relation to the Termguard System in Australia, particularly as all Termguard Licensees only use termite management agents which have proved stability in relation to soil binding and water table issues and are approved and tested by Termguard for use within the Termguard Systems. Various new products are always being designed specifically for treatment and reapplication through reticulated systems and Termguard undertakes an ongoing testing program to ensure efficacy of these termite management agents.

Q. What happens if only one section of the perimeter is disturbed during landscaping, construction or other means?

A. Only that section of the Termguard System, which has been disturbed needs to be retreated or re-injected, therefore maintaining the integrity of the Termguard System and minimizing the cost to replenish the total system(s) installed at any particular building.

Q. What happens if the Termguard System has been out of warranty for some time due to lack of regular inspections or not being replenished? Can the Termguard Warranty be reinstated?

A. Yes! The structure must have a full Timber Pest Inspection & Report in accordance with local regulatory recommendations and completed by a licensed Termguard Inspector. If the building is found clear of any termite activity, the Termguard System can be reinjected and the warranty reinstated as of the initial injection date.

Q. What happens if the home/building owner wishes to raise soil levels around the building?

A. The Termguard System can easily be adjusted and once the disturbed section is reinjected, the Warranty will continue.

Q. What happens if a section of the Termguard System is accidentally damaged?

A. That section can be either replaced or in the case of a break or fracture of the pipe, the damage can be easily repaired and the Termguard System reinstated.

Q. What happens if the licensed Termguard installer is no longer in business?

A. The home/building owner will be put into contact with other Termguard Licensed Installers in the territory. Once another Termguard Licensed Installer is selected to maintain the Termguard System, the installation details will be provided to them from Termguard records.

Q. How do I become a Termguard Licensed Installer?

A. In order to become a Termguard Licensee your company must be fully licensed in the respective state for termite control and/or currently be involved in the pretreat for termites in new construction.

Q. Is there any capital investment required to become a Termguard Licensed Installer?
