How Do You Kill a Mealybug?

How Do You Kill a Mealybug?

Mealybugs are pests that infest and weaken plants. To kill mealybugs, you need to spray the insects with a soap and alcohol mixture. This process takes only a few minutes. You need soap, oil, alcohol and a spray bottle.

  1. Choose a spray

    Choose between three types of soapy spray. The basic spray only contains soap flakes and is the easiest to make. The soapy spray with oil adheres better to the mealybugs and plants. The soapy spray with alcohol kills the mealybugs effectively because the alcohol breaks down the protective waxy layer covering the insects.

  2. Mix the ingredients

    Mix up the basic soap spray by adding 3 tablespoons of soap flakes to a gallon of water. Add 2 tablespoons of cooking oil to the basic spray to make the soap and oil spray. To make the soap and alcohol spray, mix 1/2 cup of rubbing alcohol with 1 quart of liquid soap.

  3. Apply the solution

    Pour the solution into a spray bottle. Spray the parts of the plants where the mealybugs gather, especially the lower leaves and stems. Cover the plant thoroughly with the spray, and allow it to soak the bugs for up to 2 hours. Rinse the plant with water.
