There's claims Portuguese millipedes are wreaking havoc in Wellington's Owhiro Bay - and should be declared a pest. 

The many-legged creatures have been invading homes in the small suburb at night.   

City Councillor Nureddin Abdurahman says he's heard the problem is spreading beyond Owhiro Bay to wider Wellington. 

He says if someone visits the nearby Red Rocks, millipedes could be taken into ecologically protected areas like Zealandia. 

"If it's impossible to eradicate then it needs to be contained."
