Sticks containers outside back of house (5)
I believe the answer is:
canes
'sticks' is the definition.
(cane is a kind of stick)
'containers outside back of house' is the wordplay.
'containers' becomes 'cans' (can is a kind of container).
'outside' is an insertion indicator.
'back of' indicates one should take the final letters.
The final letter of 'house' is 'e'.
'cans' placed around 'e' is 'CANES'.
(Other definitions for canes that I've seen before include "Sticks to lean on" , "Bamboo stems" , "Dogs classically" .)
