- Aphids use tiny suckers to penetrate leaves, stems and other plant parts to remove fluids. While a small number of aphids on your elephant ear won't do much harm to your plant, large groups may cause yellowing, curling and other problems.
- If you notice aphids on your elephant ear plant, you may try to remove them naturally before resorting to chemical pesticides. You may pick them off by hand or try to blast them off using a hose.
- If the aphid infestation has gotten out of control, insecticidal soap is another option for getting rid of them. Use insecticides as a last resort, however, since they can also kill beneficial insects.
