We (dot AU) have fire ants coming, with colonies detected in
Southern Queensland recently.
North though we have long had "electric ants" which infest rotting wood and look
very similar to fire ants, if somewhat smaller in size.
These guys crawl maybe 300mm up your leg before biting, so by that time there
are literally thousands of them. Like an orange cloud moving over your thongs.
They get no quarter... ant dust the whole area, end of.
Their bite is equivalent to a 24VDC burn... hence "electric ants".
Cheers.
