Invasive inspections are an additional tool in Austrapest’s Pest Inspection Services. Invasive inspections will be recommended when active termites or damage are suspected in areas such as wall cavities, trees and stumps, or when a more thorough inspection is needed prior to purchase
E.g. Borescope inspection will help locate and determine the extent of termite damage in wall cavities.
Common Tools for inspection will include – torches, probes, mirrors, stethoscopes (sound detection devices), moisture metres, computer recording technology and cameras.
We may on particular occasions recommend invasive inspections with tools such as:
• Flexible Borescope or Endoscope for inspection of suspect trees and stumps for nest location or termite damage there. A small hole to the centre of the tree or stump is needed to insert fibre optic device.
• Borescope/Technoscope provides a Fibre Optic Inspection of walls and roof and inaccessible areas of a building. For a better assessment of damage of wall frames for building on concrete slab:
• Thermal Imaging to detect thermal anomalies.
• Cut access traps to gain better visual and physical access.
• Termitrac inspections (xrays) this device is designed to detect, locate and confirm the presence of termites using a termite detection radar.
TEST DRILL TREES AND STUMPS
Often termites make their nests in trees or stumps as they provide food for them and a nesting opportunity. The pest inspector will recommend to test drill when in their professional assessment a tree or stump looks susceptible to termite activity.
Your local Austrapest Timber Pest Specialist can test drill suspect trees, stumps and send a flexible borescope inside or below the tree for a more correct assessment.
If a termite colony of a species which is a high risk of attacking your home is found, your local termite expert can apply a treatment with a registered bait or termiticide to the tree or stump and therefore protecting the house.
Note: Trees on your property should be inspected regularly by a tree surgeon as falling boughs can cause damage to property and injury to people. See some of the new pictures available, the Invasive Inspection attachment in found in reports also contains further information.
Borescope Inspection to further assess whether termites have damaged wall frames in a building and to assist in locating termites entry points.
Holes (9-12mm) are drilled in the mortar between bricks or in fibro or weatherboards for inspection with Boroscope. Holes can be plugged with cement after inspection or left open for future inspections, or plastic plug installed.
This work is always highly recommended if severe termite infestation is present especially for building on concrete slab sections, brick veneer and timber wall frames.
While this work will not be a full assessment of the damage to timbers in walls (or interfloor sections), it will help in finding termite damage, activity and entry points without having to remove all wall cladding. Wall lining can then be removed in particular areas of problem.
Note: It may not successfully discover termite activity or damage in all situations, especially where termite damage exists within a piece of timber that is not visible on the exterior surface of that timber. Drilling may also create damage to the wall, which is client responsibility.
Buildings built prior to 1982 may have wall and/or ceiling sheeting and other products including roof sheeting that contains Asbestos. Even buildings built after this date up until the early 90’s may contain some Asbestos. Sheeting should be fully sealed. Drilling, cutting or removing sheeting or products containing Asbestos is a high risk to peoples’ health therefore drilling or cutting for a Boroscope inspection can not take place in Asbestos material. You should seek advice from a qualified Asbestos removal expert.
Thermal imaging inspections are often carried out during a pre-purchase pest inspection or when more is required than just a visual inspection. Thermal Imaging unit allows us to detect thermal anomalies within timber wall studs without having to remove wall linings or to cut holes.
Infrared Thermography is a detection procedure that converts invisible heat energy in to a visible picture. Thermal infrared camera can detect temperatures within the range of 1.1°C to 343°C, with termites emitting thermal energy as high as 32°C.
The device is designed to detect, locate and confirm the presence of termites using a termite detection radar. The radar emits a microwave signal responsive to the shape of a termite while its reflection detects the movement of a target through solid material.
The termitract device makes it possible to identify infestation level and location without having to open the walls - an important step when deciding on a treatment plan.
It is particularly helpful in detecting dry wood termites which have no contact with the ground.
Strip traps or holes can be cut in Gyprock wall or ceiling inside to allow access for inspection to expose termite entry points, activity or damage. A large range of removable hole covers are available for a nicer finish.
Traps can be cut in the flooring to gain access under the inaccessible areas of a building to assess pest activity or damage there.
