Employ rat extract in floor cleaner as vermin control (9)
I believe the answer is:
mousetrap
'vermin control' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'employ rat extract in floor cleaner' is the wordplay.
'employ' becomes 'use' (synonyms).
'rat extract' becomes 'tra' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'floor cleaner' becomes 'mop' (I've seen this before).
'use'+'tra'='usetra'
'usetra' placed into 'mop' is 'MOUSETRAP'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for mousetrap that I've seen before include "inferior cheese" , "Poor cheese (colloq.)" , "Anti-rodent device" , "pest control device" , "Cheese-baited snare" .)
