Bayer’s Jim Westhead outlines why Premise Termiticide continues to be popular with pest managers, 18 years after its release.

Premise has now been on the market in Australia for over 18 years and has been in Australian field tests with CSIRO since 1993. In that time it has developed an excellent reputation for safety and reliability and is now one of the leading post-construction soil termiticides.

Jim Westhead from Bayer said, “Pest Managers changing to Premise report a dramatic decrease in their callback rates in comparison to repellent termiticides. As termites in soil do not detect Premise, they cannot find gaps in the ‘barrier’ as they do with repellent treated zones. Premise kills termites before they find any gaps.

“Termites contacting Premise in the soil will also pick up small amounts of residue and pass some on to other termites they contact. They too will die. Premise doesn’t just repel termites, it kills them and it can kill them well beyond the treated zone.

“The active ingredient in Premise has one of the lowest acute toxicity to mammals of any current soil applied termiticide. Premise is water-based. In addition, it has no smell so the occupants of the treated dwellings are undisturbed by the treatment.”

Mr Westhead highlighted some important benefits of Premise:

  • Odourless and has a favourable safety profile
  • Very reliable soil termiticide because it kills termites rather than simply repelling them
  • Water-soluble. It moves well through the soil before binding, making it easier to achieve an even, complete treated zone
  • No solvents to damage plastic containers
  • Works with nature to achieve the best results.

“With traditional under-slab treatments it isn’t possible to tell whether some sort of soil movement has led to a gap in the treatment. The installation of a reticulation system allows treatment and re-treatment of under-slab areas and the perimeter of homes, counteracting any soil movement.

“Premise is superior to all other termiticides when it comes to lateral spread through the soil. This means that it is very forgiving when it comes to reticulation systems in that it will spread beyond the required area and therefore provide an excellent soil treated zone,” added Mr Westhead.

“The reticulation system used must be capable of establishing and maintaining complete and continuous treated zones around building perimeters, service penetrations and other possible termite entry points between the structure and the termite colonies in the soil (in accordance with the Australian Standard AS3660 series).

“The initial under-slab treatment should be applied through the reticulation system as soon as possible after a 28-day period following the placement of the slab, but not more than 60 days after placement.”

Premise 200SC Termiticide is registered for use through reticulation systems as well as in direct chemical soil barrier applications, including by drill and injection.
