I do not know if this will work for squirrels but it has worked for two years for me with deer.
To prevent the animals from eating daylily buds, flower and pods I cut a piece of floating row cover in a square (its very lightweight, any light material that will let most, but not all, light through would probably work) and use a twist tie to "bag" the pod or scape branch, etc.
The spun "cloth" allows light through but hides what is inside and the deer leave the "bagged" pods (etc.) alone.
Material used for sheer curtains would probably work. Floating row covers come in different weights and I am using the second lightest one the supplier had.
