mealybug infestation on Universal
Quick answer
If your Universal has mealybug infestation, the most likely cause is: Mealybugs (family Pseudococcidae) are sap-sucking insects that appear as white, cottony masses on leaf axils, stems, and roots. They secrete a waxy protective coating and honeydew that attracts sooty mould. Indoor infestations typically begin with crawlers introduced via contaminated nursery stock or neighbouring plants, establishing colonies in sheltered crevices where airflow is poor.
Start here:
- 1. Inspect plants weekly with a flashlight, focusing on leaf undersides, stem joints, and soil line where mealybugs congregate
- 2. Spot-treat visible mealybugs using a cotton swab dipped in 70% isopropyl alcohol, dabbing directly on the insect to dissolve the waxy coating
