Head of Langley called for houses to get bugged (7)
I believe the answer is:
needled
'bugged' is the definition.
(I've seen this before)
'head of langley called for houses' is the wordplay.
'head of' suggests taking the first letters.
'called for' becomes 'needed' ('need' can be a synonym of 'call for').
'houses' means one lot of letters goes inside another.
The first letter of 'langley' is 'l'.
'l' inserted within 'needed' is 'NEEDLED'.
'to get' acts as a link.
(Other definitions for needled that I've seen before include "Piqued" , "Irked" , "Provoked or teased with knitting implements? (7)" , "Irritated (sl.)" , "Goaded or provoked" .)
