Cold Bait Matrix – Myths Busted!
How many of you experienced difficulties with cold bait matrix and lower
ambient water temperatures having the effect of actually repelling termites?
Its been a familiar story over the last year and has lead to the rumour mill
cranking about the quality and performance of Australian termite baiting
systems. From this a we’ve a heard a lot of half-truths, myths and down right
strange stories about this.
Now with warmer weather well underway we thought it timely to remind the
industry of the facts here. This is designed to help you decide which termite
bating system would be best for you.
The Bioassay results are taken from a series of laboratory evaluations
conducted by the University of Melbourne. They compare three commercial
Chitin Synthesis Inhibitors (CSIs) against the subterranean termites
Coptotermesacinaciformis(Froggatt) 1, confirmed there are indeed palatability
and efficacy differences between the three main commercial bait toxicants
available in Australia, they are as follows:
Nemesis®, with less bait substrate consumed, had a higher mortality rate
than other bait toxicants. Whilst another bait toxicant recorded a higher bait
substrate consumption its mortality rate was average. Termites fed with the
Nemesis bait toxicant were turning pale white after 31 days of exposure. The
effects on termites fed other bait toxicants were observed after 38 days of
exposure. The effect of other two bait toxicants was relatively slower than
Nemesis, but with similar toxicant action as that of Nemesis®.
So what does this all mean?
University laboratory trials have confirmed what our professional clients have
been telling us for years. Nemesis Termite Bait works faster than other
commercial baits using much less to eliminate termites in the fastest way
