Tamworth's climate and termites
Long-term Bureau of Meteorology records for Tamworth Airport show an average of about 674 mm of rain a year, with the most in summer (January averages about 85 mm). Summers are hot, with average January maximums around 32°C, and winters are cold, with July minimums around 3°C.
Subterranean termites need contact with soil or a steady source of moisture. Around Tamworth homes, that often means summer storm water pooling near the slab, garden sprinklers wetting walls, leaks in wet areas, and timber in the ground: garden sleepers, fence posts, old stumps and stacked firewood.
How termite risk changes across Australia
CSIRO says termite risk on the Australian mainland generally increases further north, with the highest risk in the subtropics and tropics, and most states have a moderate to very high risk of attack. Above the Tropic of Capricorn, the giant northern termite (Mastotermes darwiniensis) is a particularly destructive species. Tasmania is the only state CSIRO rates as negligible risk. CSIRO also notes that drywood termites, which live inside timber without needing contact with soil, are more common in humid areas such as tropical and subtropical Queensland and New South Wales.
Most damage in homes comes from subterranean termites. They usually need a connection to soil or a constant source of moisture, build mud shelter tubes to travel over things they can't eat, and generally forage within 30 m of their nest, though sometimes 100 m or more.
Signs to look for
- Mud shelter tubes on stumps, ant caps, slab edges, brickwork or inside walls.
- Hollow-sounding timber in skirting boards, door and window frames, and posts set in the ground.
- Mud packed into joints and cracks in timber.
- Damp or stained areas, especially around bathrooms, laundries and places where paving sends water towards the house.
- Winged termites (alates) swarming, particularly from inside the house.
- Small piles of gritty pellets under tiny holes in timber, which can point to drywood termites.
If you find activity, don't spray it or break open the workings. Disturbing termites can make them move and harder to treat. Leave it for the technician.
Lowering the risk around a Tamworth home
On suburban blocks and acreage alike, CSIRO's guidance includes:
- Keep garden beds, soil and mulch away from walls and below the slab edge and weep holes.
- Fix leaking taps, pipes, showers and air conditioner drains, and make sure ground and paving slope away from the house.
- Don't stack firewood or timber against the house or under a raised floor.
- Keep subfloor vents clear so the area stays dry and can be inspected.
- Make sure renovations, new paths and extensions don't bridge an existing termite barrier.
- Look in the meter box for the durable notice about the termite management system installed, and keep any paperwork from past treatments.
Treatment options a technician may suggest
Common approaches include chemical soil barriers around the slab, footings and stumps, physical barriers such as stainless steel mesh, graded stone and ant caps (usually installed during construction), baiting systems that are checked regularly and used to carry an insecticide back to the colony, and direct treatment of active termites with dusts or foams. Organochlorine chemicals were banned in Australia from 30 June 1995, so older treatments won't still be protecting a house. The technician should explain what they recommend, why, and how it will be maintained.
How often to inspect
CSIRO recommends regular termite inspections, at least once a year, because barriers and treatments can be affected by renovations, garden changes and time. Treatments don't give permanent protection against new colonies, so regular inspections matter even after a barrier has gone in. See what to expect from a termite inspection.
