This has a lot of debate surrounding it. Pine has a lot of phenols in it that are a natural insecticide. They also can cause respiratory issues and skin issues in humans and animals. However the real issues is kiln drying. If it has been forced dried the phenols are largely baked out and it is much safer. If you are SURE that it has been kiln dried it is likely ok but if you are not I'd not risk it. The problem I have is kiln dried or air dried or just branches and junk chipped who knows for sure.

On another note Cyprus is great but is also a important species that is just used to make chips. Whole trees chewed up for no reason. Look at Melaleuca mulch it is an invasive species and is being killed intentionally anyway. I live in Canada and Melaleuca mulch isn't available at all I use coco fibre.
