Els Engel:Ladybugs eat aphids, it would be paradise for them. I wouldn't put anything on the plants that works as an insecticide because there's a possibility the fish will be affected. On the other hand, I don't think one drop of detergent will kill them. We've used it before, haven't we? I think that would be the best option on the short term.
Good idea but where do we get them?
Didn't you order black soldier flies before? Do you know whether the company also sells ladybugs?
