Mealybug

Description

Mealybugs can be present in the house, the conservatory, the sun lounge or the greenhouse, few plants will escape its attention. About 4mm long, their soft bodies are a greyish-white or pink. They secrete a fluffy white waxy substance which protects their bodies and hides their eggs. They suck sap so are most susceptible to systemic insecticides that get inside the plant.
