Are the leaves of your lemon tree turning yellow and falling off? Do you notice a sticky substance on it? If you see small brown insects on the branches and foliage, they are likely shell scale insects. Learn how to get rid of them with these four steps:
What are shell scale insects?
Shell scale insects, also known as shielded mealybugs or kermes, are small brown insects that attach to plants, feed on sap, and reproduce without moving. Recognizable by their outer shell, they can cause damage to plants and lead to yellowing leaves, falling fruit, and the appearance of sooty mold.
How to get rid of shell scale insects?
- Prune infected parts: If you identify shell scale insects on your plant, the first step is to prune the infected parts. Remove the affected areas, but avoid throwing them into your compost to prevent further infestation.
- Treat the Plant with Rubbing Alcohol: For a light infestation, rubbing alcohol can be effective. Use a cotton swab dipped in alcohol to remove the mealybugs from the plant. For larger plants, create a spray mixture with 1 part alcohol and 7 parts water. Repeat the treatment every 3 days to ensure the elimination of the insects.
- Natural Treatment with Black Soap and Vinegar: To prevent a future attack and eliminate potential hidden nymphs, use black soap. Mix 2 to 3 spoons of black soap in water and apply the solution to the plant, including beneath its leaves. Additionally, vinegar is effective against mealybugs. Mix one part vinegar with two parts water and use the solution to clean the leaves and branches.Note: Avoid treating plants in direct sunlight to prevent burning.
