Safely Eliminate Mealybugs from Your Plants with Water and Rubbing Alcohol Spray

Mealybugs are a common pest that can infest indoor and outdoor plants, causing damage to the leaves, stems, and flowers. They are tiny insects that can be difficult to control, but with the right tools and techniques, you can eliminate them and prevent them from coming back. One effective and natural solution is to use a spray of water and rubbing alcohol. In this article, we will explore how to use this simple but powerful mixture to control mealybugs on your plants.

What Are Mealybugs?

Mealybugs are small, soft-bodied insects that feed on the sap of plants. They are often found in warm, humid climates and can be brought into your home on new plants or on cuttings from infected plants. Mealybugs are usually white or yellowish and are covered in a waxy substance that helps them to stick to plants. They can cause stunted growth, yellowing leaves, and even plant death if left untreated.

How Does Water and Rubbing Alcohol Spray Work?

Water and rubbing alcohol spray is an effective way to control mealybugs because the alcohol dissolves the waxy coating on the insects’ bodies, causing them to dehydrate and die. The water helps to spread the alcohol evenly over the plant and also helps to remove any dead insects or eggs that may be present.

How to Use Water and Rubbing Alcohol Spray to Control Mealybugs?

To make a spray to control mealybugs, you will need equal parts water and rubbing alcohol, as well as a spray bottle. Here are the steps to follow:

  1. Mix the water and rubbing alcohol in a spray bottle. Use 70% isopropyl rubbing alcohol, which is available at most drugstores.
  2. Shake the bottle well to ensure that the water and alcohol are thoroughly mixed.
  3. Spray the mixture directly onto the mealybugs, making sure to cover both the insects and the surrounding plant.
  4. Wait for the spray to dry before rinsing the plant with water.
  5. Repeat the treatment every few days until the mealybugs are completely gone.

Tips for Using Water and Rubbing Alcohol Spray Safely and Effectively

While water and rubbing alcohol spray is a safe and natural way to control mealybugs, there are some precautions you should take to ensure that you use it safely and effectively:

  1. Test the spray on a small area of the plant first to ensure that it doesn’t cause any damage or discoloration.
  2. Only use the spray on plants that can tolerate alcohol. Some plants, such as ferns, can be sensitive to alcohol and may be damaged by the spray.
  3. Wear gloves and eye protection when applying the spray to avoid skin or eye irritation.
  4. Avoid spraying the mixture on hot, sunny days, as the alcohol can cause the plant to burn or wilt.
  5. Store the spray bottle out of reach of children and pets.


Mealybugs can be a nuisance for gardeners, but with the right tools and techniques, they can be controlled and eliminated. Water and rubbing alcohol spray is a safe and effective way to kill mealybugs and prevent them from coming back.
