my lady bug population has been going strong for 3 months now
get one of those 5 dollar bug net things on amazon or wherever

cage/container they escape easily
this lil thing is great and if ya got a lil one makes a great thing for them to interact with
I put a blueberry or nana non citrus fruit and a cotton ball soaked for water...or sometimes lettuce or old fan leave...
you will find out where the bugs are quickly they really do flock right to them....I had a young plant that musta been really infected it was like the tree of ladybugs to the point is was preventing light to plant so many were on it...but that plant served as a breeding ground and has recovered anyways
edit..a piece of banana not the entire thing
also cut a circle of cardboard to fit bottom of the net cage as it will be way easier to empty any dead bugs etc out as they catch to the net a bit
