Managing Earwigs and Identifying Large White Calla Lilies

Earwig Control: They're Beneficial But Nuisance

Earwigs eat aphids but also chew flowers. Control without toxins:

• Barrier: Petroleum jelly or sticky tape around stems.
• Traps: Rolled newspaper or oil-filled cans at night.
• Predators: Encourage birds (birdbath), toads.
• Sanitation: Remove dense mulch near plants.

Your Calla Lily Identity

Large white callas with solid green leaves, 2–3 ft tall, in Pacific Northwest = Zantedeschia aethiopica (Arum lily).

Care for This Type

• Evergreen in mild winters; may go summer-dormant if dry.
• Needs 10 weeks post-bloom growth, then 8–10 weeks rest.
• Aggressive spreader—tubers resemble dirt clods.
• Fragrance? Z. odorata is scented; Z. aethiopica usually not.

Winter in Your Zone

Leave in ground. Mulch heavily. Remove tattered leaves in spring. They'll return vigorously.
