The most common - the grey field slug (Deroceras reticulatum) breeds in April/May and again in September/October. The garden slug (Arion hortensis) has one generation per year, breeding mainly in mid to late summer.
PS Read somewhere that mowing the lawn at night kills slugs by the thousand! ;D ;D ;D
