Hard-bodied pests that attach to plant stems and leaves, sucking sap and secreting sticky honeydew, damaging plants and difficult to control.
Scale insects are tiny, armored pests that stick to plants like bumps. They suck sap and weaken plants. They produce honeydew (sticky residue) that attracts ants and sooty mold. They're hard to kill because their armor protects them from many pesticides. Prevention is easier than cure; horticultural oil and neem oil are most effective.
Scale infestations can kill plants if severe. Early detection prevents serious problems.
