Purple Scale

Recommended Steps to Control Purple Scale

To control scale insects effectively and to limit damage, Horticultural Oil Insect Spray should be sprayed on the tree. The Horticultural oil serves to suffocate the scale and eggs. In the spring or early summer, if the crawling nymphs are present, spray the trees with Bug Buster Pyrethrin Insect Spray, to prevent the new nymphs from further infecting the tree.
