Ladybugs are Taking Over

The ladybugs at our church are trying to take over. I suggested they look into getting a Ladybug cleaner. I have heard such good things about those, but yet have talked them into trying one. Why is it that people will complain about something, but when they hear what could possibly be a remedy, they don't take the appropriate steps to eliminate the problem? Anyway, I would be curious to hear what others say about this ladybug cleaner. It might be something I would consider for my own home.
