She became frustrated with snails eating her plants and veggies. She didn't want to kill them so she she took them away to a nearby piece of waste land. But she found that they kept coming back.
Gardeners lore says that snails have a homing instinct.
She contacted the BBC radio programme Material World who put her in touch with Dr Dave Hodgson at Exeter University.
They devised a series of experiments to assess the snails' homing ability.
Ruth's results suggest that snails are able to home. She found that her snails were able to return to her garden unless they were placed more than 10 metres away.
According to Dr Hodgson:
The conventional thinking is that snails are far too simple to be able to find their way home. So if Ruth's findings are true we'll have to rethink our theories.
Of course one sample is no where near enough.
BBC Material World are organising the Great Snail Swap to provide more data. There a video on the link.
