Steps may be taken to control them (5)
I believe the answer is:
pests
'control them' is the definition.
I can't tell whether this defines the answer.
'steps may be taken' is the wordplay.
'may be taken' indicates anagramming the letters.
'steps' anagrammed gives 'PESTS'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for pests that I've seen before include "Steps (anag.)" , "Persistently annoying persons" , "Steps taken about nuisances" , "Take steps to troublesome animal." .)
