A parents group says authorities were right to call in medical experts to assess the threat from bat colonies near a school on Queensland's southern Downs.
More than 100,000 bats have taken up residence in trees near the Warwick State High School's sports oval and agriculture complex.
The school yesterday banned students from going near the trees and called in health experts to assess whether the colonies pose a risk to public health.
School P and C president Mark Wheeldon says the bats have been there for years.
"As a parent I would like to see the colony moved on," he said.
"I wouldn't like to see anything obviously inhumane go on but I certainly would think it's time the colony moved on.
"I'd like the government to come to some decision very quickly about that."
Mr Wheeldon says parents are worried about the creatures.
"They move along the Condamine River in Warwick from sort of cluster of trees to cluster of trees, but they always seem to end up down there at the school," he said.
"I wouldn't like to guess how many are down there, but it's definitely bigger than it was last year."
