Bunnies and dryer sheets

[Macaw]

I went out to the rabbit hutch today and I saw that there were an abundance of gnats so I did a little of research and saw that dryer sheets repel gnats and I was wondering it it would be safe to put them in the rabbit hutch. I would attach them from the ceiling so she couldnt eat it but would the fumes hurt her?

Research likely being a Google search.
Dryer sheets are usually toxic to animals, I'd look into different things, like a gnat trap.
