I've heard that they decision to hibernate, that they want to be in basements and places approaching that because they are cave-like and things like that, but I newly don't understand why they come into my house, cluster up contained by some corner and die. I very occasionally see them live for very long, where on earth one was alive the morning before will be see dead the subsequent day.. and they smell. Now, they are even showing up contained by my dorm room which is 3 stories off the ground so I freshly don't understand why they are around.
Could you use a portable space heating system...

Why aren't nearby urinals within homes??
i's cold and lady bugs don't hybernate or fly south. so they find a thaw place to live for the time being
