To the south-west, the western zone now the foothills of Principal Vary close to Aratula, the place fireplace ants have moved deeper into the Scenic Rim.

“That is an space the place fireplace ants have been pushing fairly exhausting,” Mr Dudgeon stated.

“We’re undecided why there reasonably than elsewhere, but it surely appears the situations for this breed there are fairly beneficial and that is the place they appear to be shifting.”
