Do rodents nest in/with mineral wool batts, as they do with fiberglass?
In my area (NM), mice and other rodents often nest in fiberglass batts, or harvest the fiberglass and move it to nearby locations to build their nests. Do they do this just as much with mineral wool batt insulation? While major rework is needed on many aspects of this property, in making short term repairs to the insulation in a few locations, I wonder if using mineral wool would be effective in deterring rodents.
On a similar question, I’ve got one room with a roughly 3/4″ x 3/4″ gap between the edge of the hardwood flooring and the wall. I would like to fill this gap, and then install baseboards. I can imagine the rodents chewing through backer rod or fiberglass insulation. Is there a good way to fill this gap, that rodents wouldn’t destroy?
