What can I do when my plant has scale insects or mealybugs?
It is hardly possible to kill scale insects or mealybugs. As long as you keep your plants in good condition, they are not likely to develop these diseases. You can recognise scale insects by the microscopic scales at the bottoms of the leaves, close to the veins on the leaves. Underneath the little scales there are tiny little insects that drink from the plant’s juices. You will find mealybugs in exactly the same spot, but they look different. They look like little wads of white fluff, that protect the bug that is hiding underneath. Since they have such wonderful hiding methods and protection strategies, they are hard to reach with bug killer substances. You had best go to your local garden centre or flower shop and ask the experts what to do in your particular case.
