Provide your houseplants with appropriate growing conditions. Healthy plants are immune to minor and intermediate infestations. Avoid ill-timed irrigation. Ensure that your greenery receives the nutrients and care needed, including pest control. Prune your trees and shrubs regularly to promote air circulation.
You can even replace plants that are prone to mealybug infestations. Replace the sensitive trees and shrubs with similar trees that aren’t susceptible to damage.
