Question for the experts-
I was finding little balls of pink attic insulation on the deck.
At first I thought something was getting under the deck into the walls. I finally figured out that they were rolling off the roof. I took some binoculars and found a hole under one of the plastic ridge vents and I could see pink insulation at the entrance to this hole. There is no insulation on the inside side of the roof just plywood. The nearest insulation is 12 ft below above the interior ceiling.
So what animal or bird is this behavior characteristic of?
What would be going in there and going down and bringing the insulation back up to the hole with them? I'm not sure if they were carrying the insulation out with them or trying to block the hole up with it, or just had it on them when exiting and pieces ended up at the entrance that way.
I first saw these insulation balls on the deck in the spring.(At that time I didn't know where they were coming from). Then nothing all summer. Then when fall hit a few weeks ago I saw the insulation ball on the deck again and figured out where they were coming from. I live in southern Wisconsin. I have not noticed any noises coming from the attic or ceiling. At night it's pretty quiet and since I figured out where "it" was getting in I have been sort of listening for something. I have been in the attics and haven't really seen anything. But that part of the attic below the hole is a sunroom and it's roof is perpendicular to the main roof, and as such is closed off from the main attic by the main roof's plywood.
Here is a picture of the intrusion location. You may be able to see the insulation in the hole if you look closely.
So what do you think is going in here. Does the seasonal nature of this tell anything?
