Sooty Mold Lingering After Insect Treatment? Here's What to Do

Verify Insect Control

After rain, check leaves: still sticky? → new honeydew → aphids/scale still active.

If Insects Are Gone

• Sooty mold is hard to remove completely.
• Strong jet of water from hose can wash off some.
• It will gradually weather away on its own.
• No need to worry if insects are controlled.
