Ladybugs are really overrated. They are helpful in theory because they eat "pests" but they are more picky than a lot of people think. Don't get me wrong, I love seeing a few laybugs and spiders cruising through my grow room, but nothing beats predatory nematodes and well calculated neem and rosemary oil warfare. Keep the ladybug, but dont expect much or waste your time stocking them, at least IMO.
