Answer: The last 2 or 3 years we have had the same thing happen. For a short time lady bugs are everywhere in the house. I'm not sure why this happens--it could be a cyclical thing where every so many years there is a population surge.<br><br>As annoying as they can sometimes be (especially when they land in my coffee!) I just try to remember what beneficial creatures they are. I can't think of anything you can do to discourage the swarm--they're just looking for a hiding place to overwinter. The warmth of the sun on otherwise cool days probably stimulates them to actively seek shelter. If you can tolerate them for this relatively short time, you'll have fewer aphids, whiteflies, and other pests in your garden next summer.
