All About Termidor

Key Takeaways

  • Termidor works on a transfer effect: termites carry the product back to the colony rather than dying on contact, so it works even though they cannot detect it
    Individual contact versus full colony elimination are different timeframes: individual termites are affected within days, the whole colony realistically takes around 90 days
  • Protection is rated for eight years: on undisturbed soil, and depends on annual inspections to stay valid
  • The Termidor Assurance Warranty covers up to $2 million: available only through an accredited applicator using genuine product
  • Genuine Termidor is only installed by accredited applicators: products sold outside professional channels are not the same registered formulation

Termidor is one of the most widely used termiticides in Australian residential pest control, developed by BASF. Older barrier products worked by repelling termites away from the treated area. Termidor works differently, termites cannot detect it, so they move through a treated zone without changing their behaviour. For the full inspection and treatment process this fits into, see our termite inspection in Melbourne page.

How Termidor’s Transfer Effect Works

Once a termite picks up fipronil, the active ingredient in Termidor, on its body, it carries the product back to the colony and passes it on through grooming and feeding. This is the transfer effect. Individual termites that make contact are affected within days. Eliminating the whole colony takes longer, since it depends on enough foraging workers carrying the product back through the nest. Realistically, that is closer to 90 days from first contact, consistent with the timeframe our termite control in Melbourne page sets out for the wider treatment process.

Termidor HE, the Current Formulation

Termidor HE, High Efficiency, is the current generation of the product, using BASF’s polymer technology for more even movement through the soil. This creates a deeper, continuous treated zone with less need for extensive drilling through concrete, and a tidier finish once the job is done.

How Long Termidor Protection Lasts

A correctly installed Termidor treatment is rated for eight years on undisturbed soil.

Our technicians most often see the warranty period shortened by changes near the treated zone rather than the product itself failing. New garden beds, retaining walls or drainage work close to the foundation are the usual cause. Annual inspections pick up these changes early, and catching them is part of what keeps the warranty valid.

Conditions that can affect the treated zone:

  • Moisture, such as a hot water system or air conditioning drip line running onto a wall edge
  • Landscaping changes near the treated zone
  • Mulch or garden beds built up against a treated wall edge
  • Drainage problems near the foundation

The Termidor Assurance Warranty

Termidor applied by an accredited applicator carries the Termidor Assurance Warranty, covering structural damage up to $2 million. Ask your technician for the current warranty terms when you book, and get them in writing. After a complete installation, you receive the certification and batch numbers needed for the warranty, with the final certificate to follow.

What a Termidor Application Involves

Our technicians trench around the property to roughly 75mm below the footing, then inject Termidor into the trench using a low volume, high pressure pump. Pathways and driveways are treated by injecting under the slab with specialist rods rather than digging them up, and drill holes in paving are finished with colour matched plugs. On an average Melbourne home this takes around 70 linear metres of treatment. Older weatherboard homes with limited under slab access tend to need more of this trenching work, while newer brick veneer builds with a continuous accessible slab edge usually need less drilling.

Only Accredited Applicators Can Install Genuine Termidor

Genuine Termidor is only available through accredited pest control operators. Products sold outside professional channels are not the same registered formulation and are not covered by any Termidor warranty. If a quote does not mention Termidor Assurance Warranty documentation, ask why before you book.
