How to Prevent Mealybugs

mealybugs on plant

There are a number of ways to prevent the attack of mealybugs. Some of the strategies are enlisted below –

  • Focus on keeping your plant healthy. Because weak plants are more susceptible to mealybug attacks. Make sure your plants are not under stressful conditions. 
  • When you buy a new plant, check it very carefully before adding it to your garden. Because mealybugs often come in with new plants that were already infested. 
  • Do not over-fertilize your plants with nitrogen. Because mealybugs love nitrogen-rich foliage. 
  • Wipe the leaves regularly with some natural ingredients like neem oil to prevent mealybugs. 
  • Spray your plant with a strong blast of water. This will prevent mealybug infestation.

  • Keep your healthy plant away from the infested ones to prevent the mealybugs from flying over to other plants.
