Regularly repair rugs, finding bugs (7)
I believe the answer is:
Here is my best explanation:
'bugs' is the definition.
'regularly repair rugs' is the subsidiary indication.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'rugs' becomes 'wigs' (rug is a slang term for a wig).
The alternate letters of 'repair' are 'ear'.
'finding' is the link.
(Other definitions for earwigs that I've seen before include "eavesdrops", "Bugs", "Elongated insects", "Insects", "listens in furtively", "Eavesdrops on the insects" and "Insect with pincers".)
