Organisers the Ladder Association have seen a record response with more than 50 pictures already received of ladder misuse.
The winning entry, with the most comments and likes on Facebook, will be announced in January following a public vote.
Ladder Association Communications and Social Media Officer, Michael Fern, said: “Thousands of people look at these horrifying images each year, and judging by the number of entries received so far, 2014 promises to bring the problem of ladder misuse into even sharper focus.
“The huge response this year shows that people know how ridiculous misusing ladders can be, but it also shows the scale of the problem, with people finding unbelievable pictures all around the UK and beyond.
“Being safe on a ladder can be as simple as taking a one-day or less training course, but many are choosing to take their lives in their hands instead.”
Idiots on Ladders is run as part of the Ladder Exchange, a campaign first launched by the Health and Safety Executive and taken over by the Ladder Association in 2012.
It lets people trade in their old, ‘dodgy’ ladders for new ones at a discount, and over the years has been responsible for taking thousands of potentially dangerous ladders out of circulation.
