More than 300 garter snakes have been removed from a house in Regina in Canada.

The house was infested by the snakes for weeks and it is believed they came in through cracks in the foundation.

Last month, the family had about 100 snakes removed from the house. Many of the snakes were hiding in cracks and crevices.

They have been taken out in bunches after the case was first brought to the attention of Salthaven West Wildlife Rehabilitation Centre.

The unwanted guests have been relocated to a nature preserve where they will be released into the wild next spring.

Salthaven spokesperson Megan Lawrence said it believes it has got most of them.

"Finding them has really slowed down so we think that's about it, though there could be a few hidden stragglers," she said in a text message to CBC News. "So I don't expect too many more."

It is believed the snakes were looking for a place to winter.

At their peak activity earlier this autumn, some had found their way upstairs into the kitchen and hallways.

Garter snakes are harmless and are welcomed by many farmers because they help control rodents.
