Air sac mite

Hi, my canary is making clicking sounds and it's very low sound and he's quiet puffed up. Ive applied him Beaphar Anti-parasite spot on which is a drop that is for all the type of mites, parasites etc.

He's now cleaning himself as he is annoyed by it, I've washed his whole cage including accessories. I just need to know what else I can do and how to get rid if it because I've warmed up my room and covered his cage with a white blanket. Any other advice please ? Thanks�
