Hit that pest! (4)

Ross

I believe the answer is:

slug

This clue is a double definition.

'hit' is the first definition.
(I know that slug is a more specific form of the action hit)

'pest' is the second definition.
(I've seen this before)

'that' acts as a link.

(Other definitions for slug that I've seen before include "Bullet; swig" , "Slimy pest" , "Shell-less mollusc ? bullet" , "slimy type" , "Small creature like snail without shell" .)

I've seen this clue in the Evening Standard.
