Preventing the Pests

Mealybugs infest a plant when it is over-watered, over-fertilized, or has high nitrogen levels. Here are a few simple ways to avoid an infestation:

Use Neem Oil to Prevent Pests

This is the number one go-to method for most house plant enthusiasts who want to keep their plants bug-free. Natria (available on is a ready-to-use effective neem oil sold at a reasonable price.

Neem oil makes it more difficult for these pests to multiply and produce eggs, so it is perfect for dealing with an infestation.

Avoid Over-Watering

You should always try to avoid over-watering your dracaena, not just for mealybugs but as a routine since it can cause problems in general for the plant.

Over-watering can eventually kill your dracaena marginata, so try to stick to a routine when watering.

Avoid Nitrogen Fertilizer

Unfortunately, dracaena excel with nitrogen fertilizer, so this is one reason why they are prone to mealybugs, as the insects are drawn to large amounts of nitrogen.

The only thing to be done here is to be aware that mealybugs will be drawn to the plant and then take steps to keep them away, such as using the neem oil mentioned above.

Quarantining New Plants

When we bring home a new plant, it’s possible that the plant is already infested with mealybugs. Before we bring it near our other plants, we should set it aside to observe it in case of infestation. A new plant should remain quarantined for two weeks.

A good way to quarantine the dracaena is to keep it in a separate room away from any other plants you have in your home.

Avoid Placing Houseplants Outside

Many house plant enthusiasts enjoy placing their plants outside during the spring and summer, which can easily lead to a bug infestation. If the dracaena marginata is outside, bugs will have easy access to it.

Keeping your plant indoors is the best way to prevent outdoor insects and pests from going near it.

Sanitize Your Gardening Equipment

Gardening equipment that has been passed around from plant to plant will quickly gather and transfer bacteria, so it’s essential to keep it clean and sanitized.

Sanitizing not only kills bacteria but will also kill any mealybug eggs and keep mealybug adults away from our tools. We must clean our tools every time we use them.

Clean Your Plant Pots

Both old and newly acquired plant pots should be sanitized between usage. Keeping them clean will prevent bacteria from building up to the point where it could destroy the plant.

Always use warm water and a gentle soap to clean your plant pots, ensuring that any debris is wiped away before placing a plant inside.

Throw Away Infected Tools

Any tools that were used on a dracaena marginata that was heavily infested should be thrown out. Throwing out infected tools will prevent a re-infestation from occurring and will keep the plant safe from any residual pests or bacteria.

Always wash your hands after handling infected tools.

Hang Your Dracaena Marginata

Hanging your dracaena marginata is an easy way to avoid mealybugs. Mealybugs can’t fly and aren’t good at reaching heights high off the ground.

Of course, this solution can only be applied when our dracaena is young and small. Hanging a large one wouldn’t be practical.

Getting Rid of Mealybugs

Mealybugs have a coating that protects them from pesticides. This can make it difficult to be rid of them with chemicals. Thankfully, there are some natural alternatives to being rid of mealybugs!

  • Ladybugs. Ladybugs are a natural predator of mealybugs. If the dracaena is kept outside, we can attract ladybugs to the garden. The ladybugs will eat the mealybugs.
  • Neem oil. A neem oil soil drench can be rid of mealybugs.
  • Alcohol spot treatment. Dip cotton swabs in 70% alcohol solution and dab the infected areas on the plant. After this is done, fill a spray bottle with 1 cup of alcohol, dawn dish soap, and 1 quart of water, then spray the entire plant.
