Mealybugs Background: The life of mealybugs
Mealybugs are often also called mealybugs and are found on plants both indoors and outdoors. The little animals, between one and twelve millimeters in size, can be found all over the world.
In Central Europe, however, the citrus mealybug and the long-tailed mealybug are the most common.
How do mealybugs damage the plant?
Mealybugs damage the plant through their sucking activities, for example on the leaves, the stem or the roots. But that's not the only thing that harms the plant.
The little animals also excrete toxins through their saliva. This inhibits the growth process of the still healthy plant.
Actually, you can clearly see the affected parts of the plant: small, white webs surround the little animals. This waxy substance serves as protection. In addition, like aphids, mealybugs secrete honeydew as a waste product.
This sticky sweet substance is highly attracted to sooty mold. If this is the case, not only is your plant infested with mealybugs, but it is also suffering from sooty fungus. So a double burden!
If the leaves of your plant are affected - e.g. from your golden fruit palm - they usually turn yellowish and curl up until they fall off. If the infestation is very severe, it can even happen that the plant dies, but of course it won't come to that with our means against mealybugs!
Where do mealybugs come from?
Unfortunately, mealybugs often appear with incorrect care or incorrect site conditions. It is therefore all the more important to pay special attention to it. Dry air and a location that is too warm or dark favor infestation by mealybugs.
These problems usually occur in the winter months, when there is often dry heated air in the rooms. In addition, the little creatures also feel particularly comfortable in soil that is over-fertilized with nitrogen.
Tip: Always make sure your home is well ventilated and avoid treating the plant with chemical fertilizers.
