Baits burrowing creatures (7)
I believe the answer is:
badgers
I believe this is a double definition.
'baits' is the first definition.
'burrowing creatures' is the second definition.
(Other definitions for badgers that I've seen before include "Pesters; black and white nocturnal animals" , "Bullies" , "Pesters like burrowing animals" , "Burrowing mammals with strong claws" .)
