What type of insulation is this?

Can you tell me what type of insulation this is? And the second is on the floor of the crawl space. Any idea what that might be?

Wild guess! Blow-in insulation?

Looks like rock wool, but I am not sure about the white particles. Just hope someone will chime in who has had experience with vermiculite to confirm it is or isn't.

I was thinking vermiculite but don't know enough to say with any certainty.

The "V" word is always hard to say, as it carries with it some bad news. To help identify it, how old is the house? Is the insulation shown extremely light?

Just in case it is vermiculite, avoid handling it or disturbing it until you are confident it is not.

The house is 112 year old, however the guy we bought it from finished the attic to make it a living space, so now it just has a crawl space and small attic about the finished space. So, we thought this insulation would be new from when he finished it, but we have no idea. It seems like there is a mix of things, the 2 I showed plus some fiberglass insulation as well.

Light as in weight, not color right? The first stuff is very light. The gray stuff I didn't touch, so I am not sure if it is lightwieght or not.

We are trying to take care of a bat problem in our house right now, so my husband has been going up there often to look for bat activity/new bat guano. I am concerned about him going up there exposing himself to anything harmful, and tracking it back in the living space and exposing our 4 kids to anything harmful.

Thanks for your input!

I don't know where you are on Minnesota (completing your profile would help with that) but there should be an environmental health agency in your area somewhere. I would call them and ask whether they can help you assess the material.

It does not look like the vermiculite I have seen. It looks mostly like blown in. Either way, working around insulation you should be wearing a mask.
