An outback Queensland town is offering a reward for a native rat that has stolen a woman's set of false teeth.

Native rat numbers have exploded in parts of western Queensland due to the exceptional wet season.

Stonehenge resident Margaret Pidgeon, south-west of Longreach, says her teeth disappeared from her bedside table and she is certain a rat is to blame.

"When I look up, there's this rat looking at me and I had nothing there to hit him with," she said.

"Anyway, when I went to get my false teeth the next morning, they are not there, they are gone.

"He didn't want my glasses, all he did was take my teeth, the bloody thing.

"He didn't waste his time the bugger, he just wanted my false teeth - probably took them back to his nest to see if he could chew them up.

"Put up a reward, 'wanted dead or alive: rat with false teeth'."

Ms Pidgeon says the reward is light-hearted but it is hard to smile without teeth.

Rat havoc

Other residents say the native rats are chewing their way through everything from walls to hats.

Stonehenge grazier Karen Emmott says she gave up counting after relocating 120 rats.

"They have 12 young every three weeks so there's probably lots more out there," she said.

"They've certainly wreaked havoc in the house.

"They've chewed the nose rest on your glasses, they've chewed those off a pair of glasses, they've eaten the crown off my Akubra hat, which was hanging on a wall.

"They chewed a very large hole into our pantry through a chipboard from underneath the pantry.

"We put a large besser brick to block it and they chewed an archway next to it and just kept coming."
