Ladybugs are attacking!!!!

So, I live in the boonies. Way out in the country town of 1400 people. Lots of bugs and mice and snakes, cows and corn fields. So I don't worry about it too much but when I pick up 15 no kidding 15 ladybugs that have died in my house in one room that is WAY too much!!!! Our windows and doors don't keep a thing out! If this was my house I woul dhave had them fixed ages ago but we rent and our landlords went to FL for the winter......awesome.
