Check these first

- Look closely for winding trails inside the leaf tissue.
- Check if the spots are sticky to the touch.
Likely causes
Holly leaf miner
PossibleHow to tell: You will see winding, snake like trails or blotches inside the leaf tissue. These are caused by larvae tunneling between the leaf layers.
What to do: Prune away and destroy the affected leaves to stop the cycle. Apply a systemic insecticide containing imidacloprid to the soil in early spring before new growth starts.
Scale insects
PossibleHow to tell: Look for small, raised brown or tan bumps on the undersides of leaves or along the stems. These insects suck sap and leave behind sticky honeydew.
What to do: Scrape off light infestations with a soft brush or fingernail. For larger issues, spray the plant thoroughly with horticultural oil or neem oil every 7 to 10 days until they are gone.

Questions people ask
- Will these spots kill my plant?
- Usually no, but heavy infestations can weaken the shrub over time. Treating the pests early keeps the plant looking its best.
- Can I just wash the spots off?
- If they are scale insects, you can wash them off with a strong stream of water or soapy water. If they are leaf miners inside the leaf, washing will not help.
