A warning not to leave your clothes on the floor, with the nasty white-tailed spider making a summer splash.

The spider - which is common in both the North and South Island - can cause a rash and swelling with its venomous bite.

Auckland-based exterminator Mark McDonald says he's getting around ten calls a week about white-tailed infestations.

He says they're mainly from west Auckland.

Experts recommend cleaning up other spider webs, and keeping clothes off the floor, to keep the pest away.
