Stung by these perhaps, destroy a nest beside tree (4,4)

'stung by these perhaps' is the definition.
The definition suggests an adverb but the answer is not.

'destroy a nest beside tree' is the wordplay.
'destroy' indicates anagramming the letters (I've seen this in other clues).
'beside' says to put letters next to each other (I've seen this in other clues).
'tree' becomes 'fir' (fir is a kind of tree).
'a'+'nest'='anest'
'anest' anagrammed gives 'eants'.
'eants' after 'fir' is 'FIRE ANTS'.
