Scale insects are sap feeding pests which attack the leaves and stems of many garden and greenhouse plants. Scale insects are often found on the underside of leaves along the leaves main vein, along stems and on the trunks of trees. The insects are protected or hidden beneath a waxy shell or scale which they secreat over their bodies. Newly-hatched scale are mobile and crawl around on the plant looking for a suitable feeding site. Once a suitable feeding site is found they settle and then become immobile whilst feeding on the plants sap. Scale insects are usually brown/grey being either flat or domed.
