Mosquitos

It is a really cold day here, I think between -29 to -35 with the windchill, and I am still killing mosquitos in my house! How is this possible, I must kill at least one every other day. I don't know where they are coming from, and it is really startng to annoy me. Shouldn't they have all dissappeared months ago? So weird, stupid bugs, but at least it's not earwigs!
