Woolly Aphids on Virginia Creeper in a Conservatory: Non-Chemical Control

Woolly aphids on Virginia creeper in an Irish conservatory. Non-chemical treatment:

1. Hard water spray (sink hose) to knock off aphids.
2. Rubbing alcohol spray (full strength or 1 tbsp dish soap/quart water) on all leaf surfaces.
3. Repeat every 3 days for 3 weeks—consistency is key.

Check undersides of leaves. Alcohol kills on contact. Soap spray works too. Persistence wins.
