I did the same thing a couple of years ago. I was over run with afids, so I colected lady bugs from outside and voila...afids gone. Then the rest of the summer I was over run in the house with the lady bugs. They were everywere, on the windows, in the corners, even in the cupboards. They enentualy die off and you will vacume them up, but finding dry crunchie beatlels everywere is pretty gross. But good luck with it.
