Identification and Treatment Guide

Updated: April 17, 2022

Elephant plants, also known as elephant ears or Colocasia, are popular ornamental plants with large, striking foliage that can add a tropical feel to any garden or indoor space. However, like any plant, elephant plants are susceptible to pests, which can cause damage and even kill your beloved plant. In this article, we will cover the most common elephant plant pests, how to identify them, and the best treatments to keep your plant healthy and thriving.

Spider Mites

Spider mites are tiny pests that suck the sap out of the leaves of your elephant plant. They are difficult to spot with the naked eye but can cause significant damage if left untreated. Signs of spider mite infestation include yellowing leaves, webbing on the undersides of leaves, and tiny black or brown spots on the leaves.

Treatment: The best way to treat spider mites is to spray your plant with a solution of neem oil and water. You can also use insecticidal soap or horticultural oil. Be sure to spray the undersides of leaves where spider mites like to hide.

Mealybugs

Mealybugs are small, white insects that look like bits of cotton. They feed on the sap of your elephant plant by piercing the leaves and stems with their mouthparts. Signs of mealybug infestation include sticky residue on leaves, distorted growth, and yellowing leaves.

Treatment: The best way to treat mealybugs is to remove them manually with a cotton swab dipped in rubbing alcohol. You can also use insecticidal soap or neem oil.

Scale Insects

Scale insects are small, oval-shaped pests that attach themselves to the stems and undersides of leaves of your elephant plant. They suck sap from the plant and excrete a sticky substance called honeydew, which can attract other pests like ants. Signs of scale insect infestation include yellowing leaves, sticky residue on leaves, and distorted growth.

Treatment: The best way to treat scale insects is to remove them manually with a cotton swab dipped in rubbing alcohol. You can also use insecticidal soap or horticultural oil.

Aphids

Aphids are small, pear-shaped insects that feed on the sap of your elephant plant. They can be found on the undersides of leaves and stems and reproduce rapidly, so it’s essential to catch them early. Signs of aphid infestation include yellowing leaves, distorted growth, and sticky residue on leaves.

Treatment: The best way to treat aphids is to spray your plant with a solution of water and dish soap or insecticidal soap. You can also introduce natural predators like ladybugs or lacewings to your garden to eat the aphids.

Fungus Gnats

Fungus gnats are tiny flies that are attracted to the moist soil in your elephant plant’s pot. They lay their eggs in the soil, and the larvae feed on the roots of your plant. Signs of fungus gnat infestation include yellowing leaves, stunted growth, and small black flies hovering around your plant.

Treatment: The best way to treat fungus gnats is to let the soil dry out between waterings and avoid overwatering your plant. You can also use sticky traps or introduce nematodes to eat the larvae.
