Tips for avoiding and managing termites

During building construction

The risk of attack can be reduced if effort is made to remove stumps, roots, off-cuts and to properly consolidate the soil to minimise cracks in concrete slabs. Termites do not eat concrete but if it cracks, they may widen the crack and find their way into any timber walls.

When buying a house

It is strongly recommended that before you buy a house, you have an expert inspect it for termite activity. The cost of a full report is minimal compared with the expense of repairs.

If you uncover termites

Should you uncover termites, try to put things back as they were. Ripping out floorboards, architraves, etc, may kill a few termites in those timbers, but in doing so you have lessened the chances of an expert effectively treating the main nest. The termites will re-group and probably choose to attack another section of the house structure.

Long-term protection

Protection in the long-term can be gained by the application of chemical or physical barriers (or both) to prevent termites from penetrating the structure. An Australian Standard has been written on the subject. The aim is to keep timber away from soil contact and to encourage termites to build a mud tube out in the open where it can be seen during a regular, careful inspection.

Termite barriers are designed to stop concealed access and force termites into the open where their mud tunnels can be more easily detected. Physical barriers range from small graded stone particles to fine termite-resistant, tough mesh and chemically impregnated composite products. 

You must be proactive in your decision making process. And most importantly, you must arrange for appropriately qualified operators to carry out regular inspections. You should also be fully informed about ongoing maintenance requirements.

Tips for avoiding damage by termites

• Choose a termite management system to suit your preferences and the needs of the type of construction
• Understand the system of termite management and maintenance requirements for your house
• Have a pest controller inspect the house every 12 months if you are in a high hazard area
• If you are concerned about existing or potential infestation, you should contact your local pest control company

Maintenance/housekeeping tips

• Check your property and building regularly for termite activity to reduce the risk of damage
• Plumbing leaks, drainage problems and roof leaks should be addressed promptly, as termites are attracted by damp conditions
• Garden beds should not be built up against walls, as this allows termites an undetectable entry point to the building
• Do not block or cover sub-floor ventilation with garden beds or paving
• Do not stack materials against walls, as this can allow termites to enter without early detection
• Sub floor areas should be well ventilated and vents should not be obstructed
• Storage of cellulose products in the sub floor space should be avoided
• Use termite resistant timber for works around the property, including retaining walls
• Use metal stirrups for verandah and gateposts
• Clean and check timber decks regularly
• Do not build rainwater tanks up against walls, as this may allow termites an undetectable entry point to the building
