Mealybugs: Identification and Control

What are Mealybugs?

Mealybugs are tiny, white insects that feed on the sap of plants. They’re often found on houseplants, especially cacti and succulents. Mealybugs have a white, waxy coating that makes them look like tiny cotton balls.

Symptoms of Mealybug Infestation

• White, waxy insects on leaves and stems
• Sticky honeydew on leaves
• Sooty mold on leaves

How to Control Mealybugs

Prevention:

• Inspect new plants before bringing them indoors.
• Move outdoor plants to areas where birds can eat mealybugs.
• Dispose of fallen leaves that may have mealybugs or eggs.

Treatment:

• Small infestations: Remove mealybugs with tweezers.
• Large infestations: Use a predatory ladybird called Cryptolaemus montrouzieri. Release them in summer when temperatures are warm.
• Spray plants with fatty acids or plant oils: Apply several times to kill mealybugs.
• Severe infestations: Destroy affected plants to prevent spread.

Tips:

• Avoid overwatering plants, as this can attract mealybugs.
• Keep plants clean and free of debris.
• Monitor plants regularly for signs of mealybug infestation.
