Pests
Snails and Slugs on Colocasia
Commonly affects: Colocasia esculenta (Taro / Elephant Ear)
Irregular holes appear in leaves, often with a silvery slime trail visible nearby, especially after rain or in consistently moist growing conditions.
Potential Causes
- 1Snails and slugs attracted to Colocasia's moist growing environment and large, soft leaves, which are an easy and favoured food source
- 2Outdoor or bog-style plantings being particularly susceptible given the naturally damp conditions
- 3Nighttime feeding activity making the pests themselves hard to spot during the day
Solution Steps
- 1Hand-pick snails and slugs in the evening or early morning when they're active
- 2Use iron phosphate-based slug bait, which is safer around pets and other wildlife than older metaldehyde-based products
- 3Create physical barriers like copper tape around containers
- 4Remove hiding spots like dense mulch or debris directly around the base of the plant
Prevention Tip
Colocasia's naturally moist growing conditions make it especially attractive to snails and slugs â check leaves for holes and slime trails regularly if grown outdoors.
