IMAGINE sharing your home with this monster.

This snakeskin was found in a north Queensland ceiling last week - it's a whopping 6.7m long and could soon be on display at Griffith University.

The skin belongs to a scrub python that moved into the Pelt family home at Cannonvale near Airlie Beach about five years ago, returning every winter to hibernate.

"It's too big to get out, it just comes and goes as it pleases," 22-year-old Morgan Pelt said.

"She usually comes out in October but this year she came out a month earlier because of the warm weather."

BACKYARD BATTLE: Snakes go to war over mating rights

Ms Pelt's parents Adrian and Suzette have their house inspected each year for termites and often uncover a skin shed by their scaly friend.

Ms Pelt says this was their largest find yet.

"The biggest one on record is 8.5m, so it's getting there," she said.

"I'm doing a course at university preserving animals and I said to the lecturer, 'My parents just pulled out a huge snake skin, would you want it for the ecology museum?'"

Ms Pelt, an environmental management student, said scrub pythons were not venomous and killed their prey by catching and constricting it.

"They usually eat possums, bats or small wallabies, things like that," she said.

While a resident monster python might scare some, Ms Pelt said her mum wasn't concerned by its presence, having grown up on a farm in Africa where 5m pythons are common.

"The snake just runs around, it never bothers anyone," Ms Pelt said.

"The only thing they are worried about is it getting so big that it falls through the rafters.

"They might have to get someone to catch and relocate it somewhere."

The snake skin was posted to Ms Pelt and will be given to university staff to assess.
