Songbird EssentialsSE7018 Hummer Helper Nesting Material Refill

What time of year do I put this out?

How much do you get? Will it fit in a regular suet holder?

Does this really include the cage? Only the refill is pictured. Update: I contacted the company, and it is just the refill. They are looking into changing the title.

Is this cotton organic / pesticide free?
