You wouldn’t think it to look at them – but the best way to get to slugs and snails is through their noses.
As gardeners struggle to keep the pests under control in the humid summer weather, experts have found that planting strong-smelling marigolds, lavender and geraniums is a sure-fire way to keep slugs and snails at bay.
A scientific study has shown for the first time that the pests are put off not only by unpleasant tastes, but also ‘volatile scents’.

Researchers at the University of Plymouth analysed the feeding preferences of hundreds of snails using 14 different grassland plant species.
They scientists found that the creatures kept away from strong-smelling chemicals, similar to those that create the smell of freshly cut grass, which can also be found in herbs such as basil and mint.
Dr Mick Hanley, who led the study published in the journal Annals of Botany, said: ‘Snails and slugs often like the small amount of chemicals in some seedlings, and will eat them, but keep away from mature plants such as marigolds.
‘Planting these flowers next to the vegetables you want to protect could be a simple strategy.’
The research has also been useful for farmers who want to protect crops without the use of pesticides.
