Meyer Lemon Sticky Leaves: Aphids/Thrips Honeydew, Neem Solution

Diagnosis

Sticky leaves + brown hollow structures on leaf undersides = aphids or thrips. They suck sap, excrete honeydew (sticky varnish). "Hollow things" = shed skins or parasitized mummies.

Why Soapy Water Failed

Contact kill only. No residual. Reinfestation from missed individuals or new hatchlings within days.

Neem Oil Protocol

100% pure neem oil: 1 tsp + 1 tsp mild soap per quart water.
Spray thoroughly: All surfaces, especially leaf undersides.
Repeat 7 days: Catches new hatch.
Then as needed: Only on new growth if pests return.

Why Neem Wins

Systemic-ish (absorbs into leaf).
Insect growth regulator (stops nymphs maturing).
Antifeedant (adults stop feeding).
Preserves lady beetles, lacewings, parasitic wasps.

Wipe honeydew off first (damp cloth), then spray neem. Sticky residue blocks light and hosts sooty mold.
