As nocturnal mollusks, slugs tend to reside in dark places during the day, such as hedgerows, refuse or rotting logs and timber. Their habitats are very often close to areas of human presence, such as gardens or parks.
These hiding places are also where slugs will lay their eggs. Laid in large quantities, the eggs are held together by a sticky substance that yellows prior to hatching. Slugs develop gradually. They can lay dormant for up to 4 years.
They feed on the shoots and leaves of most field and garden crops, with a particular preference for ripe strawberries, tomatoes and head cabbage, which also provides good shelter during the day.
