ill-treats

I'm a little stuck... Click here to teach me more about this clue!

'a bite and does some damage' is the definition.
I can't judge whether this defines the answer.

'after a charming trill takes' is the wordplay.
'after' says to put letters next to each other.
'a charming' indicates anagramming the letters.
'takes' becomes 'eats' (eating is a kind of taking).
'trill' anagrammed gives 'illtr'.
'illtr' next to 'eats' is 'ILL-TREATS'.

Can you help me to learn more?

(Another definition for ill-treats that I've seen is " Abuses".)
