How to get rid of mealy bugs on your plants?

Mealybugs, small soft-bodied insects, feed on plant sap and are commonly found as pests affecting both indoor and outdoor plants.

Identification of mealybugs includes observing white, cottony masses on stems, leaves, or leaf axils. They excrete honeydew, a sticky substance that fosters the growth of black sooty mold, often attracting ants. Scale insects are a variant of mealybugs.

To address mealybug infestations, follow these steps:

1. Quarantine Infected Plants:
   • If multiple plants are present, isolate the infested one to prevent the spread of mealybugs.
2. Prune Affected Parts:
   • Trim and discard heavily infested plant sections using clean, sharp scissors or pruning shears.
3. Utilize a Strong Water Jet:
   • Employ a forceful water spray on the plant to dislodge mealybugs, repeating this process regularly to maintain control.

After these initial measures, consider the following methods to control infestations:

4. Neem Oil + Dishwasher Soap + Water Mixture:
   • Combine 1 tsp neem oil, 1/3 tsp mild dishwashing soap, and 1L water. Apply the solution to affected plants, preferably in the morning or evening when insects are less active and when the sun is not too strong. Ensure thorough coverage of all plant surfaces. This mix is not ideal for succulents if not done the right way.
5. Insecticidal Soap:
   • Mix 25g potassic soap with 1L water, choosing a soap free of additives. Apply this solution to affected plants, or opt for ready-made insecticidal soaps. Our top pick is the Mercadona potassic soap and here is a video explanation by Toni (@lahuertinadeltoni) on how to prepare the insecticidal soap mixture. You can also buy readymade ones for your plants.
6. Beneficial Insects:
   • Introduce natural predators like ladybugs or predatory beetles to help control mealybug populations.
7. Repeat Treatments:
   • Persistence is key. Regularly repeat the chosen treatment to target the new ones that may hatch after the initial intervention.
8. Enhance Plant Health:
   • Boost plant health by providing adequate light, water, and nutrients, making the plant more resilient against pests.

Consistency and patience are crucial in managing mealybug infestations. While complete elimination may take time, regular care will aid in the plant’s recovery. If you are still struggling, our community is here to help with our plant doctor service.
