A toad-killing spree in north Queensland has eliminated 14,000 of the environmental pests in the third annual "Toad Day Out".

The event is the brainchild of Queensland state MP for Dalrymple Shane Knuth - a stereotypically no-nonsense north Queenslander.

Mr Knuth hates cane toads, as do most people in his region.

So volunteers were rallied again this year on Saturday night, with Townsville, Charters Towers and Cairns the designated killing fields.

"We collected up to 14,000 canetoads, that's 4000 more than last year," Mr Knuth told AAP.
