COUNCILS are warning parents to keep their children away from the corpses of bats and flying foxes killed by scorching temperatures, as hundreds of thousands of the animals perish and litter the ground.

Bat conservation workers and vets spent much of the past two days removing bodies, humanely euthanasing survivors and finding homes for orphaned babies.

WEATHER LATEST: STORMS TO FOLLOW THE HEAT

They estimate up to 10 colonies - stretching between Brisbane, Ipswich and the Sunshine Coast - may have been affected, with tens of thousands from each "just dropping and dying".

Ipswich council staff on Sunday worked beside them at Redbank to clear them from the gardens and facilities.

Ipswich councillor Paul Tully said parents needed to be especially vigilant during hot weather to ensure their children remained safe.

"Young children could be attracted to the bats on the ground but there could be serious health risks if they pick them up," he said.

"Residents should report any other incidents to the council."

Bat Conservation and Rescue Queensland president Louise Saunders said conservation workers had found the distressing task "awful" - especially given they could only take in so many orphans.

"These (hot weather) events are really impacting on them," she said.

"It's a horrible, cruel way to die. We're just trying to deal with the animal welfare side of things."

Ms Saunders said those closer to the coast had fared much better than those further away - with many colonies moving inward to escape the heat.

She said there had been reports of "mass mortalities" throughout southeast Queensland.

"We're talking hundreds of thousands of flying foxes," she said.

"Anything over 43 degrees and they just fall. We're just picking up those that are just not coping and are humanely euthanasing what we can."
