Aphids and thrips are listed on the exact species profile. The Zantedeschia guide also warns of fungal or bacterial rots and rhizome rot from excessive wetness.
How to care for a calla lily
Water calla lily little or not at all while it is dormant, then increase water when shoots appear without leaving the rhizome pot in standing water.

Find a bright, steady position
Light and temperature
For an indoor container after shoots appear, place Zantedeschia in a warm, bright spot. Outdoor full-sun or partial-shade guidance does not establish how many hours of direct indoor sun the plant should receive.
Check the mix, drainage and pot
Watering, drainage and repotting
During dormancy, water little or not at all. Increase watering when shoots appear, and never leave the container standing in water because the rhizome can rot.
Use peat-free loam-based potting compost and place the dormant rhizome with its top just showing above the medium. No species-specific indoor repot interval is supplied.
