Weeping Bald Cypress: Sticky Sap = Aphids, Not Tree Sap

The Real Culprit: Aphids

Sticky "mist" on deck/walkway = aphid honeydew, not tree sap. Aphids suck leaf juices, excrete sugar-rich honeydew → black sooty mold grows on it.

Control Options

Contact sprays: acephate (Orthene), bifenthrin (Talstar), malathion, pyrethrum, etc.
Systemic: acephate (Orthene) soil drench/injection—less harm to beneficials.
Hose blast: Strong water spray weekly knocks them down.

After Aphids Are Gone

Rain washes away honeydew and sooty mold. Ask nursery for tree-safe aphid product.
