'bug in the house' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'it's muted curiously' is the wordplay.
'curiously' indicates anagramming the letters.
'its'+'muted'='itsmuted'
'itsmuted' anagrammed gives 'DUST MITE'.

Can you help me to learn more?

(Another definition for dust mite that I've seen is " Tiny arachnid linked to asthma - edit tums (anag)".)
