About adjectives (Can I use "little creatures" after "nasty")

Whats the mistake at this phrase:
I think louse are nasty little creatures

I know I can say: I think louse are nasty.
My question is: Can I use “little creatures” after “nasty”

Yes, but make “louse” plural. I think lice are nastly little creatures.

thank you - simple mistake, but I didn’t realize.

did you really mean “nastly”?

I’m sure Barb meant to type ‘nasty’, jctgf.

She sure did!
