What does a scale insect look like?

Scale insects have four growth stages, namely, eggs, larvae, adults and residual shells. The growth and changes in each stage are different, but everyone likes to hide behind the leaves. Scale insects can be divided into white, yellow, brown, black and gray, which are the differences after adults, but the most common is white.

Scale insects grow by constantly absorbing the juice of plant stems and leaves, so the growth state of branches and leaves harmed by scale insects will become worse, and they are more prone to yellowing and deformation, and some leaves will also have curly changes, so once the leaves are found to have some changes, it is necessary to check the branches and leaves to see if the scale insects are at work.

Infected with pests is serious. After the scale insects can be cleaned, we should take the plants out of the pot in time and clean the roots, because some larvae will attach to the roots, so we must eliminate them all and disinfect them thoroughly before we can go to the pot again.
