Will aphids kill my Italian arum?

They rarely kill the plant outright, but they drain its energy and can cause leaf distortion. It is best to remove them promptly.

Can I use household soap to kill them?

Use a dedicated insecticidal soap rather than dish soap, as some household soaps can be too harsh for the leaves.
