How to Get Rid of Mealybugs on Dew Plant

Updated: April 12, 2022

Dew plants, also known as Drosera, are carnivorous plants known for their sticky leaves that trap and digest insects. However, these plants can sometimes fall prey to mealybugs, a common pest that can cause damage to the plant if left untreated. In this article, we will discuss how to identify and get rid of mealybugs on dew plants.

Identifying Mealybugs on Dew Plants

Mealybugs are small white insects that resemble tiny pieces of cotton. They are soft-bodied and typically found in groups on the undersides of leaves or in the crevices of the plant. Signs of mealybug infestation include distorted leaves, yellowing or wilting foliage, and sticky honeydew secretions. These pests can weaken and kill a dew plant if left untreated.

Getting Rid of Mealybugs on Dew Plants

1. Isolate Infected Plants

The first step in getting rid of mealybugs is to isolate infected plants from other plants to prevent the spread of the pest. Place the infected dew plant in a separate area where it can be treated individually.

2. Remove Visible Bugs

Using a cotton swab dipped in rubbing alcohol, gently remove visible mealybugs from the plant. Be sure to dispose of the swab and any bugs that are removed.

3. Spray with Insecticidal Soap

Insecticidal soap is a natural and effective way to control mealybugs on dew plants. Mix one tablespoon of insecticidal soap per quart of water and spray the entire plant, including the undersides of leaves and crevices where bugs may be hiding. Repeat this process every five to seven days until all signs of mealybugs are gone.

4. Use Neem Oil

Neem oil is an organic insecticide that can also be used to control mealybugs. Mix one teaspoon of neem oil per quart of water and spray the entire plant, making sure to cover all areas thoroughly. Repeat this process every seven to 14 days until all signs of mealybugs are gone.

5. Introduce Natural Predators

Ladybugs and lacewings are natural predators of mealybugs and can be introduced to the garden to help control the pest. You can purchase ladybugs and lacewings from gardening stores or online retailers.

Preventing Mealybug Infestations

Preventing mealybug infestations is key to keeping dew plants healthy. Here are some tips to keep in mind:

  • Keep plants healthy with proper watering and fertilization.
  • Inspect plants regularly for signs of pests and diseases.
  • Quarantine new plants for a few weeks before introducing them to your garden.
  • Avoid over-fertilizing, as this can attract pests.
  • Practice good hygiene by cleaning up fallen leaves and debris from around plants.

By following these preventative measures, you can reduce the likelihood of mealybug infestations on your dew plants.


Can I use dish soap instead of insecticidal soap?

While dish soap may kill mealybugs, it can also harm the plant. Insecticidal soap is specifically designed for use on plants and is less likely to cause damage.

How long does it take to get rid of mealybugs?

It may take several weeks to completely get rid of mealybugs on dew plants. Be patient and consistent with your treatment methods.

Will mealybugs come back after treatment?

Mealybugs can return if preventative measures are not taken. Regular inspections and good hygiene practices can help prevent future infestations.
