Eradicating Aphids on Indoor Bird of Paradise: Complete Soil and Foliage Treatment

Identifying the Infestation

Small black elliptical insects (1.5mm) on flowers and stalks, not leaves – classic aphid behavior. They cluster on tender new growth and flower parts.

Nuclear Option: Total Reset

Move plants outdoors
Remove from pots, discard all soil (eggs are in it)
Wash pots with bleach solution, rinse thoroughly
Spray entire plant (crown + root ball) with horticultural oil OR insecticidal soap
Let sit several hours
Repot in fresh sterile soil
Hose off all dead insects and residue

Why This Works

Heat from the house hatched eggs in the nursery soil. The oil/soap suffocates active insects; soil replacement eliminates the reservoir. Quarantine outdoors for a few days before bringing back in.
