One way to get rid of a creepy-crawly? Shake a leg (4,2,2)

Ross

I believe the answer is:

step on it

I believe this is a double definition.

'one way to get rid of a creepy-crawly?' is the first definition.
(as in stepping on a creepy-crawly to kill it)

'shake a leg' is the second definition.
(I've seen this in another clue)

(Other definitions for step on it that I've seen before include "improve rate of advance" , "to flatten an insect?" , "Go for speed" , "to take advantage of escalating opportunity" , "How might one kill an ant" .)

I've seen this clue in The Telegraph.
