I know that most cps die from fungus, gnats, or aphids and I know that ladybugs and ladybug larvae eat aphids. So is it recommend to use ladybugs to eat the aphids or just use pesticide. I don't have any aphids but I would like to know, cause there's a field near my house that has a plant that has a alot of ladybugs and larvae and pupa but no sign of aphids or any small bug.
