Karen, we have the same problem. About 5 years ago, my cousin's daughter caught ladybugs and released them in our house and we can't get rid of them either.
I suggest you and I start an ebay company immediately. We could pool our resources. However, we will now be taxed on our vast earnings on ebay!! The bad thing is if you squish them by mistake, they leave a red mark on the walls. We sometimes make ladybug soup out of them. <img border="0" alt="[beer]" title="" src="graemlins/beer.gif" /> Doug just gobbles it up.
