...that blue insulation board in my attic??

I have been scanning the threads looking to see if anyone has asked about having mice living in their R19 insulation in their attic, and what might be done about it besides using D-con. I am wondering if I could just take out all that old insulation and put in some of that blue insulation board type stuff up in the attic so the mice couldn't burrow in it like they have in the R19.
Is it ok to put blue insulation board up there?? or won't it work the same for some reason? Has anyone tried it?
I just purchased this house, I'm not living in it yet, but I don't want to have mice in the attic.
Thanks to all who reply.

You're looking at a pretty big job trying to remove all that insulation. As for mice - well, in my limited experience, those little boogers will find a way to chew through the blue board too.... They're looking for warmth - not necessarily a "soft place to nest". I've had them chew through plasterboard and use the remnents for their nesting...

I'd spend my energy trying to find and plug their access (which can be nearly impossible)... and getting rid of the existing colony.

since you are not living there yet have the pest guy fumigate and kill those rascals. As far as rigid over blown insulation... R-7 per inch when you are using rigid. It is not as effective as blown. Blown loose fills over all air spaces. No gaps no issues. As far as replacing the existing, once they are dead they are gone. As thezster stated plug all holes. Field mice can squeeze into ridiculousy small holes.

good luck

One thing I haven't seen mentioned is the danger in disturbing mouse droppings.
Hanta (sp) virus, a deadly disease caused by some species of mice, is a major problem in some areas.

I would suggest you contact your local health officials or you will find a lot on the net if you search this topic.
