Acrylic sweeper agitated spiders, for example (6-8)

I believe the answer is:

creepy-crawlies

I'm a little stuck... Click here to teach me more about this clue!

'spiders for example' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'acrylic sweeper agitated' is the wordplay.
'agitated' indicates anagramming the letters.
'acrylic'+'sweeper'='acrylicsweeper'
'acrylicsweeper' with letters rearranged gives 'CREEPY-CRAWLIES'.

Can you help me to learn more?
