Subterranean Termites have been in the environment for an estimate of some 400 million years. They do one thing and one thing only, break down dead decaying trees in a forest situation to allow new growth. Why does this have anything to do with your home? Simply because we have a lot of different words for a dead tree. Top plates, bottom plates, studs, noggins, stringers, bearers, joists, hip beams, skirting boards, door jambs, paper, cardboard, timber flooring, etc. etc… Also known as all the components that are required to make your house a home. A CSIRO Survey indicates about 1 in 3 dwellings have Termites within the boundary and most homes are at risk. Particularly if well-established gum trees are within 100 meters of the building.
Detection and Identification:
The Australian Standards A.S.3660.2 is simply put for the detection, prevention and eradication or Subterranean Termites from existing dwellings. The first and most important aspects of The Australian Standards Guidelines, is to detect any and all Termite activity within the property grounds. This includes a written and detailed inspection report explaining all areas inspected i.e. sub floor, roof void, interior, exterior area, garden and landscaping, fences, other timber structures and surrounding trees etc. The report may also include, recommendations such as; removal of any timber contact with soil i.e. bark gardens against the house, patio timbers in direct contact with soil, untreated retaining timbers, high moisture areas which may require specialist intervention (plumbers) and increases airflow to sub floor areas, just to name a few examples. The professional technician will also provide a detailed and comprehensive Treatment Program for your property.
Nest Treatments/Eradication Procedures:
In the event our Professional Technician do find Termite Infestations at your property, you will be advised to move to the initial Termite Treatments.
Direct Nest Treatments: There are one of 4 types of treatments that our professional team will encounter:
Ground Mound: These nest treatments are obviously the simplest to treat purely because they are easiest to identify and are easily controlled by the introduction of either an aqueous or dusting treatment directly to the nest.
Arboreal Nest: Much the same as Ground Mounds, these nests are easily controlled through the introduction of either an aqueous or dusting treatment directly to the nest.
Subterranean Nest: These nests are the most difficult and require the highest level of competency achievable within the industry to detect and treat. Treatment to the crown root area of a susceptible and active tree requires drilling into the crown root area and flooding using an aqueous solution then resealing the hole. In the situation of a tree Subterranean Nest, such as under an infill area of a patio, behind timber retaining walls, rock retaining walls etc. in these situations it is highly recommended that a baiting system be installed and serviced as per the Australian Standards.
Sub Nest: These nests are the most disturbing to all home owners as they are found within the house structure itself and highly active and destructive. Treatment of these nests through the introduction of either a foaming or dusting treatment directly to the Sub Nest and internal workings.
These treatments are where the exterior and sometimes the interior of the structure are chemically treated with a liquid solution against the foundation walls, effectively creating a treated area or zone that abuts the house so as to impede future/further termite attack and damage. This is achieved by drilling holes, at between 150-300mm spacing’s in concrete that is attached the exterior of the dwelling, and trenching all exposed soil areas to the tops of the foundations before applying a registered termiticide at 100l per cubic metre as per A.S.3660.2
There are 2 Liquid Treatments available on the market within Australia.
One is known as a repellent. This product is designed so that when the Termites, through their tunnelling and scouting activities encounter the product in the soil attached to the dwelling and are then repelled by the product with the theory being they do not return to this area. These treatments are by far the cheapest preventative treatment to choose.
The second is known as a non-repellent. This product although the more expensive of the choices is by far the smarter alternative as it works on not just killing the termites that are attacking the house but also works on effectively eradicating the primary nest and colony.
Termite Baiting is not new technology. The objective is simple, by installing an appealing and easily digestible timber that is contained within an approved bait station that is installed directly into the soil, within the first 30 centimetres of the ground at between 4-6 meter intervals around the house structure. The Termite in its foraging habits discovers the timber and starts to consume it making it an easily and readily available high way back to the nest. Once this is achieved the Professional Technician studiously introduces an I.G.R (Insect Growth Regulator) to the active timber resulting in the Termites consuming and sharing the poisonous I.G.R with the rest of the colony, ending with the death of the primary queen and cessation of the nest.
Are Baiting Stations considered to be a successful treatment option?
This is a highly contentious issue within the industry. This is due to the fact that Termites really do randomly forage in search of food, meaning there is no way that you can guarantee that any Termite will find one, let alone all of the Bait Stations places around the property. We at Exterminator Pest Control firmly believe that as an overall Subterranean Termite Treatment Plan that Baiting Stations have their place. This options along with all other treatment options make up part of our unparalleled Subterranean Termite Treatment Procedures. These options will be discussed at length and in detail with our Professional Technicians.
Commonly found throughout Queensland – particularly in urban areas or where eucalypt gum trees are highly prevalent.
Destructive Nature – Coptotermes acinaciformis are highly destructive to buildings and other timber structures. They are the most widely distributed and destructive timber pest in Australia, accounting for more than 70% of the serious damage to buildings in Australia. A single colony may consist of more than one million termites. A most voracious timber pest … one to be taken seriously.
Nest Location – Coptotermes acinaciformis are a very secretive termite species; they build their nest out of sight, often within the base of eucalyptus or other susceptible trees, or completely under the ground; often within an enclosed patio or under concrete on ground flooring which is ideal for moisture retention, temperature and humidity control within the termite colony’s central nest.
Coptotermes acinaciformis can also construct subsidiary termite nests away from the main colony nest. A subsidiary White-ant nest can be contained in a wall cavity of a building where there is a reliable moisture source, for example, from a leaking shower recess or faulty guttering or rusted down pipes.
Area of Distribution – Commonly found in eastern Queensland – particularly along the entire coast-line, the Great Dividing Range and adjoining slopes.
Identification – this species tends to “gouge” the affected timber and has a fetish around nails used in construction. When you first find them, you will often see a major soldier (6mm in body length) and a minor soldier (4mm in body length).
Destructive Nature – Schedorhinotermes intermedius are highly destructive to buildings and other timber structures. If mostly major (larger) soldiers are sighted, then they will most likely be a large colony with the potential to cause severe and rapid damage to structural timbers of a building or other timber structures.
Nest Location – Schedorhinotermes intermedius commonly build their nest in tree stumps, in the root crown of the living, dead and debilitated trees, under houses or within enclosed patios or other areas where timber has been buried or stored in contact with the soil.
Area of Distribution – Commonly found in eastern Queensland – particularly prevalent in the coastal and mountain regions along the entire eastern side of Queensland.
Destructive Nature – Nasutitermes walkeri can be destructive to damp timbers often a serious problem where the sub-floor of a building is damp and ventilation is poor with resulting wood decay or fungal growth.
Nest Location – Nasutitermes walkeri build their nest in trees on the main trunk or in the fork of a large branch.
Area of Distribution – Commonly found throughout Queensland – particularly in urban areas or where eucalypt gum trees are highly prevalent.
Destructive Nature – Heterotermes ferox are destructive to damp timbers and are usually found attacking fences, poles and other timber structures subject to wood decay from weathering or from being in contact with the soil. This species is often confused with the more aggressive and destructive Coptotermes acinaciformis species. Correct identification is essential.
Nest Location – Heterotermes ferox often build their colony nest next to stumps, logs, or other timber in direct contact with the soil where some wood decay or rotting is prevalent.
Dampwood termites form small independent nests which often attack sick or dead trees, decaying stumps or mould timber in the ground; they are seldom found in dry timbers in buildings.
Drywood termites occur mostly in tropical areas, where the atmospheric humidity is constantly above 75 percent. The introduced and highly destructive West Indian drywood termite, Cryptotermes brevis, is rarely located in Queensland. Specialist eradication procedures involve wrapping the entire building in plastic and using methyl bromide fumigation
