Kitty where in zone 5 are you? A month ago we had them by the hundreds here. They came in to winter. If it warms up some I may be able to find a few of them. But how do you ship them.

I was told that placing banana peels around inhibits/repels aphids. You may want to try it. I've put several in my enclosed porch and so far haven't seen aphids on the hundred of plants. I didn't spray the plants, either.

I don't need to imagine all those ladybugs flying around my house!I ran around here one spring scraping them off my windows by the dozens
It's been crazy here with them the past ten years. You'll not have much luck with them as they are dormant right now. I have five hibernating in the ceiling corners of this room right now.
