Pest identification
What's eating my nandina obsessed?
Aphids
Signs: Colonies on new growth tips; sticky honeydew, leaf curl, and sooty mold develop quickly in warm weather
Control: Blast with water; apply insecticidal soap or neem oil spray; reduce high-nitrogen feeding which promotes soft aphid-attractive growth
Scale insects
Signs: Hard or waxy bumps on bark and stems; yellowing leaves, reduced vigor, sooty mold on drips
Control: Apply horticultural oil in late winter; use a systemic insecticide for severe or persistent infestations
Japanese beetle (Popillia japonica)
Signs: Skeletonized leaves with transparent veining; adult beetles cluster and feed in groups from July onward
Control: Hand-pick adults in early morning; use milky spore disease or beneficial nematodes in lawn soil to target larvae

What is eating my nandina obsessed?
Nandina Obsessed ('Seika') shares the strong pest resistance typical of Nandina domestica cultivars. Aphids are the most likely problem on lush new spring growth. Scale insects occasionally colonize stems. In the eastern and midwestern US, Japanese beetles will feed on foliage if populations are high in the surrounding area.
