Five termite services.
From a $360 annual inspection through to a $20K whole-of-structure Mastotermes remediation. We hold the NT Pest Control licence under the Medicines, Poisons and Therapeutic Goods Act + AEPMA membership + AS 3660 Termite Inspector certification required for all of it.
Pre-purchase inspection
AS 4349.3 detailed inspection with written report for property settlement. Sub-floor stumps, roof void, perimeter, garden, moisture-meter readings, Mastotermes mound scan on rural acreage. Same-day or next-day. ~$480–$680 standard residential.
See pre-purchase inspections →Annual inspection (AS 3660.2)
The mandatory yearly inspection AS 3660 expects on every Australian home. Detailed sub-floor and roof-void audit, perimeter scan, moisture readings. Written report. ~$320–$480 depending on size and whether you’re urban Darwin or rural acreage.
See annual inspections →Chemical soil barrier
Termidor SC or Premise 200SC non-repellent termiticide injection around the perimeter. 8–10 year barrier. Mastotermes needs deeper-than-southern injection volumes because the colony footprint is wider. $2,800–$6,500 standard, more for rural reticulation.
See chemical barriers →Baiting systems
Sentricon Always Active, Exterra or Trelona ATBS in-ground stations around the perimeter. Termites take bait back to the colony, kill the queen. Excellent against Mastotermes — bait reaches diffuse colonies that miss soil barriers. Install $2,000–$3,800 + ~$420/yr.
See baiting systems →Pre-construction barrier
For new builds and major renovations — AS 3660.1 reticulation + chemical perimeter, OR physical barrier (Kordon, HomeGuard) + perimeter chemical, OR hybrid baiting. Builder needs the Form 16 Termite Management Certificate for Form 21 occupation handover. ~$2,200–$4,200.
See pre-construction →Three things every Darwin termite inspection should get right.
Mastotermes darwiniensis — the world’s most destructive termite.
Australia has 350+ termite species. Three are economically destructive country-wide; in the Top End, the dominant species is Mastotermes darwiniensis, the Giant Northern Termite. It’s the only surviving member of family Mastotermitidae, the most primitive termite lineage alive. Mastotermes colonies are diffuse, not centralised — a single colony can spread across 1–2 hectares with multiple satellite nests, which is why standard southern-Australia inspection patterns miss them. Mastotermes will eat timber, paper, leather, plastic, rubber, soft metals (lead flashing, copper insulation, sometimes aluminium fly-screen frames), and high-lime concrete. You don’t inspect for Mastotermes by looking for one mud-tube near a sub-floor bearer — you scan the whole 1–2ha around the building including outbuildings, fence lines, garden timbers and any bushland boundary.
High-set on stumps + monsoonal moisture = perfect storm.
Greater Darwin’s older housing stock — 1960s–80s high-set timber on concrete or steel stumps — was designed for cyclone uplift, not termite resistance. Sub-floor crawl-spaces stay humid for 6–9 months of the year (wet season + build-up + early dry), softening bearers and joists. Combined with chronic ant-cap failure on older stumps and decades of garden mulch piled against stump bases, a Coptotermes or Mastotermes colony can establish in sub-floor undetected for years. About 18–22% of our pre-purchase inspections on pre-1990 high-set homes find active or recently-active termite evidence. Annual inspection is non-negotiable on these properties; many clients move to 6-monthly.
Chemical barriers expire — check when yours was last renewed.
Pre-1995 chemical-barrier treatments used organochlorines (chlordane, dieldrin) which last 40+ years but are now banned. Post-1995 treatments used permethrin or bifenthrin (10–15 year life). Modern non-repellent chemicals (Termidor SC, Premise 200SC) last 8–10 years. A 1995 permethrin barrier is now 30 years old — expired. A 2015 Termidor treatment is in its last year. Look at the Termite Management Certificate (Form 16) installed under the meter box or in the electrical sub-board — if there isn’t one, the property has been unprotected for some time. The NT’s tropical climate shortens chemical half-life; we’ve seen 10-year-rated barriers test inactive at 7–8 years on north-facing soil. We can confirm at inspection and quote renewal.
Where we inspect & treat.
City of Darwin, City of Palmerston and rural Litchfield Council. High-density inspection rounds across Casuarina, Nightcliff and Parap; Mastotermes acreage work at Howard Springs, Humpty Doo, Berry Springs, Bees Creek and Virginia. Same-day or next-day inspections most weeks.
From booking to written report — 5 stages.
Booking
Phone or online quote-request. Most inspections same-day or next-day. Pre-purchase inspections we’ll usually fit within 24h for settlement deadlines, including same-day for Casuarina / Nightcliff urban runs.
Site visit
60–90 min on-site for urban Darwin; 2–3h on rural acreage. Sub-floor stumps, roof void, perimeter, garden, fence-line, outbuildings, bushland boundary. Moisture-meter readings. Thermal-imaging if suspect activity.
Written report
AS 3660.2 or AS 4349.3 format report with photos, moisture readings, suspect areas, chemical-barrier status, Mastotermes mound mapping (rural), treatment recommendations. Within 24h.
Treatment (if needed)
Chemical soil injection (1–3 days for rural acreage) or baiting station install (half-day urban, full day rural). Active Mastotermes infestation = same-week treatment with monitoring schedule.
Certificate + monitoring
Form 16 Termite Management Certificate (filed under meter box) or Pre-Purchase Report for the buyer’s solicitor. Annual monitoring schedule. Insurance-grade documentation.
