Where Do Slugs Spend the Winter?

4-1-14  slug under bark 223Slugs mate and lay eggs in the spring and fall, and can live 12 to 15 months. Eggs laid in the fall overwinter in this stage, and hatch in the spring. Some members of this generation of slugs may die in the fall, while others hibernate underground or beneath loose bark. The survival rate of the hibernators depends upon the harshness of the winter. Look in and under rotting logs to find slug eggs, and behind the bark of dying trees to find slug hibernacula.

  1. Hibernacula is such a wonderful word. It has such a quiet, holy sound to it.

  2. no offense to the slugs but if they and their eggs don’t survive the winter, that would be one positive result of the record cold and freezes. when spring does come, my gardens will be the happier without them!

  4. Though I do admire the slug, however humble, I don’t appreciate them overpopulating my yard. Perhaps the best way to keep that from happening next summer is to look for, and destroy, as many eggs as possible. I’m sure it won’t be a fatal blow to the population. But it might save some of my plants.
