Attic insulation

When I took the facias off today and looked in I could see the whack of insulation is plugging up the air to some of the soffit areas so i made up a stick with a piece of wood on the end and pushed it back in.

I noticed at the ends that there was quite a buid up. If I wanted to you cant put those pink things in that keep the insulatino away from the roof underside so how do you deal with insulation in the four corners of fhe roof? They are plugged on this home and I assume I have to get in there and pull the insulation back in the corners as well?



It is some kind of blown in stuff and yeah will wear a mask, can I put a board down in the attic to walk on insualtion looks like it is 2 feet deep??
