Who's not so civil, entering home with tenants on vacation? (9)

'who's not so civil entering home with tenants on vacation?' is the definition.
I can't judge whether this defines the answer.

'not so civil entering home with tenants on vacation?' is the wordplay.
'not so civil' becomes 'ruder' ('rude' can be the opposite of 'civil' so perhaps 'ruder' is reasonable for 'not so civil').
'entering' means one lot of letters goes inside another.
'home with' becomes 'in' ('he's home' can mean 'he's in'. I am not sure about the 'with' bit.).
'on vacation?' suggests removing the centre (after the inside letters have vacated the word).
'tenants' with its centre taken out is 'ts'.
'in'+'ts'='ints'
'ruder' placed inside 'ints' is 'INTRUDERS'.

Can you help me to learn more?
