Rodent-killers stir up some rats (10)

I believe the answer is:

mousetraps

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

'rodent-killers' is the definition.
I can't judge whether this definition defines the answer.

'stir up some rats' is the wordplay.
'stir' indicates an anagram.
'up'+'some'+'rats'='upsomerats'
'upsomerats' with letters rearranged gives 'MOUSETRAPS'.

Can you help me to learn more?
