A brazen possum has been caught red-handed with enough greens to last a lifetime after busting into a Brisbane Bunnings nursery department in the middle of the day.

The common brushtail possum was filmed happily munching on a lettuce seedling by Yvonne McRostie, who shot the footage last month at the Carseldine store on Brisbane's north.

The video was posted on the ABC Brisbane Facebook page this morning where it has been viewed more than 70,000 times.

Ms McRostie said a staff member eventually came along and shooed the creature away.

"It looks like it was a regular occurrence there, it went into the wall of pots and went up there," Ms McRostie said.

"I couldn't believe it happened in the middle of the day, I've never seen a possum in the middle of the day."

A Bunnings spokeswoman said its stores "from time to time encounter visits from wildlife, including possums".

"Typically they leave on their own accord, however in situations where the safety of our customers and team or the animal may be compromised we contact the relevant authority to safely remove the animal from the store," the spokeswoman said.

Possum's appearance mostly pleases Facebook crowd

The response to the possum's presence in the hardware store was mixed on Facebook.

"Lol it's a smorgasbord and he wants to try everything on the menu," one said.

"For some reason this makes me feel happy," another said.

"He must be soooo hungry to brave it & stay chomping down those succulent greens where people can clearly see him, poor little munchkin."

Others were not so impressed.

"B**** possums they have just about annihilated my garden," someone said.

Others offered up advice for how to keep possums away from their plants.

"I have built my veggie garden with a big pest mesh blocking the animals and birds and it worked," another said.
