Relatively non toxic indoor aphid spray

[NeurotrashWarrior]

A couple of my house plants have annoying aphids who manage to exist even when I constantly pick them off. They shed and drop the sticky stuff everywhere.

Iirc does washing up liquid help? Any advice? It's a succulent and a giant angel wing begonia.

I have tried diluted vinegar and baking soda which helps a bit

Water with a bit of washing up liquid in it. The washing up liquid is a wetting agent to make sure the aphids are thoroughly wet with no air bubbles and therefore drown. It also washes off the sugary excretions.

Thank you!
